Detailed Description

template<class T>
class Teuchos::ArrayRCP< T >

Array reference-counted pointer class.

This is a reference-counted class similar to RCP except that it is designed to use reference counting to manage an array of objects that use value semantics. Managing an array of objects is very different from managing a pointer to an individual, possibly polymorphic, object. For example, while implicit conversions from derived to base types is a good thing when dealing with pointers to single objects, it is a very bad thing when working with arrays of objects. Therefore, this class contains those capabilities of raw pointers that are good dealing with arrays of objects but excludes those that are bad, such as implicit conversions from derived to base types.

Note that all access will be checked at runtime to avoid reading invalid memory if HAVE_TEUCHOS_ARRAY_BOUNDSCHECK is defined which it is if --enable-teuchos-abc is given to the configure script. In order to be able to check access, every ArrayRCP must be constructed given a range. When HAVE_TEUCHOS_ARRAY_BOUNDSCHECK is defined, this class simply does not give up a raw pointer or raw reference to any internally referenced object if that object does not fall with the range of valid data.

Constructor & Destructor Documentation

template<class T >
Teuchos::ArrayRCP< T >::ArrayRCP ( ENull  null_arg = null) [inline]

Initialize ArrayRCP<T> to NULL.

This allows clients to write code like:

   ArrayRCP<int> p = null;

or

   ArrayRCP<int> p;

and construct to NULL

Definition at line 118 of file Teuchos_ArrayRCP.hpp.

template<class T>
Teuchos::ArrayRCP< T >::ArrayRCP ( T *  p,
size_type  lowerOffset,
size_type  size,
bool  has_ownership,
const ERCPNodeLookup  rcpNodeLookup = RCP_ENABLE_NODE_LOOKUP 
) [inline]

Construct from a raw pointer and a valid range.

Postconditions:

WARNING! You should avoid manipulating raw pointers and use other methods to construct an ArrayRCP object instead!

Definition at line 133 of file Teuchos_ArrayRCP.hpp.

template<class T>
template<class Dealloc_T >
Teuchos::ArrayRCP< T >::ArrayRCP ( T *  p,
size_type  lowerOffset,
size_type  size,
Dealloc_T  dealloc,
bool  has_ownership 
) [inline]

Construct from a raw pointer, a valid range, and a deallocator.

Postconditions:

WARNING! You should avoid manipulating raw pointers and use other methods to construct an ArrayRCP object instead!

Definition at line 172 of file Teuchos_ArrayRCP.hpp.

template<class T>
Teuchos::ArrayRCP< T >::ArrayRCP ( size_type  size,
const T &  val = T() 
) [inline, explicit]

Construct allocating an array of size n and filling.

Postconditions:

Definition at line 124 of file Teuchos_ArrayRCP.hpp.

template<class T>
Teuchos::ArrayRCP< T >::ArrayRCP ( const ArrayRCP< T > &  r_ptr) [inline]

Initialize from another ArrayRCP<T> object.

After construction, this and r_ptr will reference the same array.

This form of the copy constructor is required even though the below more general templated version is sufficient since some compilers will generate this function automatically which will give an incorrect implementation.

Postconditions:

  • this->get() == r_ptr.get()
  • this->count() == r_ptr.count()
  • this->has_ownership() == r_ptr.has_ownership()
  • If r_ptr.get() != NULL then r_ptr.count() is incremented by 1

Definition at line 197 of file Teuchos_ArrayRCP.hpp.

template<class T >
Teuchos::ArrayRCP< T >::~ArrayRCP ( ) [inline]

Removes a reference to a dynamically allocated array and possibly deletes the array if owned.

Deallocates array if this->has_ownership() == true and this->count() == 1. If this->count() == 1 but this->has_ownership() == false then the array is not deleted (usually using delete []). If this->count() > 1 then the internal reference count shared by all the other related ArrayRCP<...> objects for this shared array is deincremented by one. If this->get() == NULL then nothing happens.

Definition at line 206 of file Teuchos_ArrayRCP.hpp.


Member Function Documentation

template<class T>
ArrayRCP< T > & Teuchos::ArrayRCP< T >::operator= ( const ArrayRCP< T > &  r_ptr) [inline]

Copy the pointer to the referenced array and increment the reference count.

If this->has_ownership() == true and this->count() == 1 before this operation is called, then the array will be deleted prior to binding to the pointer (possibly NULL) pointed to in r_ptr. Assignment to self (i.e. this->get() == r_ptr.get()) is harmless and this function does nothing.

Postconditions:

  • this->get() == r_ptr.get()
  • this->count() == r_ptr.count()
  • this->has_ownership() == r_ptr.has_ownership()
  • If r_ptr.get() != NULL then r_ptr.count() is incremented by 1

Return if the underlying object pointer is still valid or not.

The underlying object will not be valid if the strong count has gone to zero but the weak count thas not.

NOTE: Null is a valid object pointer. If you want to know if there is a non-null object and it is valid then !is_null() && is_valid_ptr() will be true.

Postconditions:

Definition at line 612 of file Teuchos_ArrayRCP.hpp.

template<class T >
bool Teuchos::ArrayRCP< T >::has_ownership ( ) const [inline]

Returns true if this has ownership of object pointed to by this->get() in order to delete it.

See ~ArrayRCP() above.

Returns:
If this->get() == NULL then this function always returns false. Otherwise the value returned from this function depends on which function was called most recently, if any; set_has_ownership() (true) or release() (false).

Definition at line 619 of file Teuchos_ArrayRCP.hpp.

template<class T >
T * Teuchos::ArrayRCP< T >::release ( ) [inline]

Release the ownership of the underlying array.

After this function is called then the client is responsible for deleting the returned pointer no matter how many ref_count_ptr<T> objects have a reference to it. If this->get() == NULL, then this call is meaningless.

Note that this function does not have the exact same semantics as does auto_ptr<T>::release(). In auto_ptr<T>::release(), this is set to NULL while here in ArrayRCP<T>:: release() only an ownership flag is set and this still points to the same array. It would be difficult to duplicate the behavior of auto_ptr<T>::release() for this class.

Postconditions:

Returns:
Returns the value of this->get()

Returns true if the smart pointers share the same underlying reference-counted object.

This method does more than just check if this->get() == r_ptr.get(). It also checks to see if the underlying reference counting machinery is the same.

If the object pointer is non-null, assert that it is still valid.

If is_null()==false && strong_count()==0, this will throw DanglingReferenceErorr with a great error message.

If is_null()==true, then this will not throw any exception.

In this context, null is a valid object.

template<class T >
ArrayRCP< T > arcp ( typename ArrayRCP< T >::size_type  size) [related]

Allocate a new array just given a dimension.

Warning! The memory is allocated using new T[size] and is *not* initialized (unless there is a default constructor for a user-defined type).

When called with 'size == 0' it returns a null ArrayRCP object.

template<class T >
ArrayRCP< T > arcpCloneNode ( const ArrayRCP< T > &  a) [related]

Allocate a new ArrayRCP object with a new RCPNode with memory pointing to the initial node.

The purpose of this function is to create a new "handle" to the array of memory with its own seprate reference count. The new ArrayRCP object will have a new RCPNodeTmpl object that has a copy of the input ArrayRCP object embedded in it. This maintains the correct reference counting behaviors but now gives a private count. One would want to use arcpCloneNode(...) whenever it is important to keep a private reference count which is needed for some types of use cases.

template<class T2 , class T1 >
ArrayRCP< T2 > arcp_const_cast ( const ArrayRCP< T1 > &  p1) [related]

Const cast of underlying ArrayRCP type from const T* to T*.

The function will compile only if (const_cast<T2*>(p1.get());) compiles.

Examples:
ArrayRCP_test.cpp.
template<class T2 , class T1 >
ArrayRCP< T2 > arcp_reinterpret_cast ( const ArrayRCP< T1 > &  p1) [related]

Reinterpret cast of underlying ArrayRCP type from T1* to T2*.

The function will compile only if (reinterpret_cast<T2*>(p1.get());) compiles.

Warning! Do not use this function unless you absolutely know what you are doing. Doing a reinterpret cast is always a tricking thing and must only be done by developers who are 100% comfortable with what they are doing.

Examples:
ArrayRCP_test.cpp.
template<class T2 , class T1 >
ArrayRCP< T2 > arcp_reinterpret_cast_nonpod ( const ArrayRCP< T1 > &  p1,
const T2 &  val = T2() 
) [related]

Reinterpret cast of underlying ArrayRCP type from T1* to T2* where T2 is a non-POD (non-plain-old-data).

The function will compile only if (reinterpret_cast<T2*>(p1.get());) compiles.

This function is used to reinterpret cast an array of plain-old-data (POD) (e.g. int or char) into an array of real objects. The constructors will be called on each of the memory locations with placement new and the destructors will get called when the last RCP goes away.

Warning! Do not use this function unless you absolutely know what you are doing. Doing a reinterpret cast is always a tricking thing and must only be done by developers who are 100% comfortable with what they are doing.

template<class T2 , class T1 >
ArrayRCP< T2 > arcp_implicit_cast ( const ArrayRCP< T1 > &  p1) [related]

Implicit case the underlying ArrayRCP type from T1* to T2*.

The function will compile only if (T2 *p = p1.get();) compiles.

Warning! Do not use this function unless you absolutely know what you are doing. While implicit casting of pointers to single objects is usually 100% safe, implicit casting pointers to arrays of objects can be very dangerous. One std::exception that is always safe is when you are implicit casting an array of pointers to non-const objects to an array of const pointers to const objects. For example, the following implicit conversion from a array pointer objects aptr1 of type ArrayRCP<T*> to

 ArrayRCP<const T * const>
 aptr2 = arcp_implicit_cast<const T * const>(ptr1);

is always legal and safe to do.

template<class T1 , class T2 >
void set_extra_data ( const T1 &  extra_data,
const std::string &  name,
const Ptr< ArrayRCP< T2 > > &  p,
EPrePostDestruction  destroy_when = POST_DESTROY,
bool  force_unique = true 
) [related]

Set extra data associated with a ArrayRCP object.

Parameters:
extra_data[in] Data object that will be set (copied)
name[in] The name given to the extra data. The value of name together with the data type T1 of the extra data must be unique from any other such data or the other data will be overwritten.
p[out] On output, will be updated with the input extra_data
destroy_when[in] Determines when extra_data will be destroyed in relation to the underlying reference-counted object. If destroy_when==PRE_DESTROY then extra_data will be deleted before the underlying reference-counted object. If destroy_when==POST_DESTROY (the default) then extra_data will be deleted after the underlying reference-counted object.
force_unique[in] Determines if this type and name pair must be unique in which case if an object with this same type and name already exists, then an std::exception will be thrown. The default is true for safety.

If there is a call to this function with the same type of extra data T1 and same arguments p and name has already been made, then the current piece of extra data already set will be overwritten with extra_data. However, if the type of the extra data T1 is different, then the extra data can be added and not overwrite existing extra data. This means that extra data is keyed on both the type and name. This helps to minimize the chance that clients will unexpectedly overwrite data by accident.

When the last RefcountPtr object is removed and the reference-count node is deleted, then objects are deleted in the following order: (1) All of the extra data that where added with destroy_when==PRE_DESTROY are first, (2) then the underlying reference-counted object is deleted, and (3) the rest of the extra data that was added with destroy_when==PRE_DESTROY is then deleted. The order in which the objects are destroyed is not guaranteed. Therefore, clients should be careful not to add extra data that has deletion dependencies (instead consider using nested ArrayRCP objects as extra data which will guarantee the order of deletion).

Preconditions:

  • p->get() != NULL (throws NullReferenceError)
  • If this function has already been called with the same template type T1 for extra_data and the same std::string name and force_unique==true, then an std::invalid_argument std::exception will be thrown.

Note, this function is made a non-member function to be consistent with the non-member get_extra_data() functions.

Examples:
test/MemoryManagement/RCP_test.cpp.
template<class T1 , class T2 >
T1 & get_extra_data ( ArrayRCP< T2 > &  p,
const std::string &  name 
) [related]

Get a non-const reference to extra data associated with a ArrayRCP object.

Parameters:
p[in] Smart pointer object that extra data is being extracted from.
name[in] Name of the extra data.
Returns:
Returns a non-const reference to the extra_data object.

Preconditions:

Note, this function must be a non-member function since the client must manually select the first template argument.

Examples:
test/MemoryManagement/RCP_test.cpp.
template<class T1 , class T2 >
const T1 & get_extra_data ( const ArrayRCP< T2 > &  p,
const std::string &  name

Parameters:
p[in] Smart pointer object that extra data is being extracted from.
name[in] Name of the extra data.
Returns:
Returns a const reference to the extra_data object.

Preconditions:

Note, this function must be a non-member function since the client must manually select the first template argument.

Also note that this const version is a false sense of security since a client can always copy a const ArrayRCP object into a non-const object and then use the non-const version to change the data. However, its presence will help to avoid some types of accidental changes to this extra data.

template<class T1 , class T2 >
T1 * get_optional_extra_data ( ArrayRCP< T2 > &  p,
const std::string &  name 
) [related]

Parameters:
p[in] Smart pointer object that extra data is being extracted from.
name[in] Name of the extra data.
Returns:
Returns a non-const pointer to the extra_data object.

Preconditions:

Postconditions:

  • If name and T1 have been used in a previous call to set_extra_data() then return !=NULL and otherwise return == NULL.

Note, this function must be a non-member function since the client must manually select the first template argument.

Examples:
test/MemoryManagement/RCP_test.cpp.
template<class T1 , class T2 >
const T1 * get_optional_extra_data ( const ArrayRCP< T2 > &  p,
const std::string &  name 
) [related]

Get a pointer to const extra data (if it exists) associated with a ArrayRCP object.

Parameters:
p[in] Smart pointer object that extra data is being extracted from.
name[in] Name of the extra data.
Returns:
Returns a const pointer to the extra_data object if it exists.

Preconditions:

Postconditions:

  • If name and T1 have been used in a previous call to set_extra_data() then return !=NULL and otherwise return == NULL.

Note, this function must be a non-member function since the client must manually select the first template argument.

Also note that this const version is a false sense of security since a client can always copy a const ArrayRCP object into a non-const object and then use the non-const version to change the data. However, its presence will help to avoid some types of accidental changes to this extra data.

template<class Dealloc_T , class T >
Dealloc_T & get_nonconst_dealloc ( const ArrayRCP< T > &  p) [related]

Preconditions:

template<class Dealloc_T , class T >
const Dealloc_T & get_dealloc ( const ArrayRCP< T > &  p) [related]

Return a const reference to the underlying deallocator object.

Preconditions:

Note that the const version of this function provides only a very ineffective attempt to avoid accidental changes to the deallocation object. A client can always just create a new non-const ArrayRCP<T> object from any const ArrayRCP<T> object and then call the non-const version of this function.

template<class Dealloc_T , class T >
const Dealloc_T * get_optional_dealloc ( const ArrayRCP< T > &  p) [related]

Return a pointer to the underlying non-const deallocator object if it exists.

Preconditions:

Postconditions:

  • If the deallocator object type used to construct p is same as Dealloc_T then return!=NULL, otherwise return==NULL
Examples:
test/MemoryManagement/RCP_test.cpp.
template<class Dealloc_T , class T >
Dealloc_T * get_optional_nonconst_dealloc ( const ArrayRCP< T > &  p) [related]

Return a pointer to the underlying const deallocator object if it exists.

Preconditions:

Postconditions:

  • If the deallocator object type used to construct p is same as Dealloc_T then return!=NULL, otherwise return==NULL

Note that the const version of this function provides only a very ineffective attempt to avoid accidental changes to the deallocation object. A client can always just create a new non-const ArrayRCP<T> object from any const ArrayRCP<T> object and then call the non-const version of this function.

Examples:
test/MemoryManagement/RCP_test.cpp.
template<class TOrig , class Embedded , class T >
const Embedded & getEmbeddedObj ( const ArrayRCP< T > &  p) [related]
