Constructors/Destructor
 ParameterEntry ()
 Default Constructor.

 Destructor.
Set Methods
ParameterEntryoperator= (const ParameterEntry &source)
 Replace the current parameter entry with source.
template<typename T>
void setValue (T value, bool isDefault=false, const std::string &docString="", RCP< const ParameterEntryValidator > const &validator=null)
 Templated set method that uses the input value type to determine the type of parameter.

void setValidator (RCP< const ParameterEntryValidator > const &validator)
 Set the validator.

 Create a parameter entry that is an empty list.
Get Methods
template<typename T>
T & getValue (T *ptr) const
 Templated get method that uses the input pointer type to determine the type of parameter to return.
anygetAny (bool activeQry=true)
 Direct access to the Teuchos::any data value underlying this object. The bool argument activeQry (default: true) indicates that the call to getAny() will set the isUsed() value of the ParameterEntry to true.
const anygetAny (bool activeQry=true) const
 Constant direct access to the Teuchos::any data value underlying this object. The bool argument activeQry (default: true) indicates that the call to getAny() will set the isUsed() value of the ParameterEntry to true.
Attribute/Query Methods
bool isUsed () const
 Return whether or not the value has been used; i.e., whether or not the value has been retrieved via a get function.
bool isList () const
 Return whether or not the value itself is a list.
template<typename T>
bool isType () const
 Test the type of the data being contained.
bool isDefault () const
 Indicate whether this entry takes on the default value.

 Return the (optional) validator object.
I/O Methods
std::ostream & leftshift (std::ostream &os, bool printFlags=true) const
 Output a non-list parameter to the given output stream.

(Note that these are not member functions.)

template<typename T>
T & getValue (const ParameterEntry &entry)
 A templated helper function for returning the value of type T held in the ParameterEntry object, where the type T can be specified in the call. This is an easier way to call the getValue method in the ParameterEntry class, since the user does not have to pass in a pointer of type T.
bool operator== (const ParameterEntry &e1, const ParameterEntry &e2)
 Returns true if two ParameterEntry objects are equal.
bool operator!= (const ParameterEntry &e1, const ParameterEntry &e2)
 Returns true if two ParameterEntry objects are not equal.
std::ostream & operator<< (std::ostream &os, const ParameterEntry &e)
 Output stream operator for handling the printing of parameter entries.


Detailed Description

This object is held as the "value" in the Teuchos::ParameterList std::map.

This structure holds a Teuchos::any value and information on the status of this parameter (isUsed, isDefault, etc.). The type of parameter is chosen through the templated Set/Get methods.

Member Function Documentation

ParameterEntry & Teuchos::ParameterEntry::operator= ( const ParameterEntry source  ) 

Replace the current parameter entry with source.

Definition at line 49 of file Teuchos_ParameterEntry.cpp.

template<typename T>
void Teuchos::ParameterEntry::setValue ( value,
bool  isDefault = false,
const std::string &  docString = "",
RCP< const ParameterEntryValidator > const &  validator = null 
) [inline]

Templated set method that uses the input value type to determine the type of parameter.

Note:
  • Invalidates any previous values stored by this object although it doesn't necessarily erase them.
  • Resets 'isUsed' functionality.

Definition at line 277 of file Teuchos_ParameterEntry.hpp.

void Teuchos::ParameterEntry::setAnyValue ( const any value,
bool  isDefault = false 
)

Set the value as an any object.

This wipes all other data including documentation strings.

Warning! Do not use function ths to set a sublist!

void Teuchos::ParameterEntry::setValidator ( RCP< const ParameterEntryValidator > const &  validator  ) 

Set the validator.

Definition at line 76 of file Teuchos_ParameterEntry.cpp.

template<typename T>
T & Teuchos::ParameterEntry::getValue ( T *  ptr  )  const [inline]

Templated get method that uses the input pointer type to determine the type of parameter to return.

Note:
This method will cast the value to the type requested. If that type is incorrect, an std::exception will be thrown by the any_cast.

Definition at line 294 of file Teuchos_ParameterEntry.hpp.

any & Teuchos::ParameterEntry::getAny ( bool  activeQry = true  )  [inline]

Definition at line 301 of file Teuchos_ParameterEntry.hpp.

const any & Teuchos::ParameterEntry::getAny ( bool  activeQry = true  )  const [inline]

Constant direct access to the Teuchos::any data value underlying this object. The bool argument activeQry (default: true) indicates that the call to getAny() will set the isUsed() value of the ParameterEntry to true.

Definition at line 310 of file Teuchos_ParameterEntry.hpp.

Test the type of the data being contained.

Definition at line 326 of file Teuchos_ParameterEntry.hpp.

bool Teuchos::ParameterEntry::isDefault (  )  const [inline]

Indicate whether this entry takes on the default value.

RCP< const ParameterEntryValidator > Teuchos::ParameterEntry::validator (  )  const [inline]

Return the (optional) validator object.

Definition at line 339 of file Teuchos_ParameterEntry.hpp.

std::ostream & Teuchos::ParameterEntry::leftshift ( std::ostream &  os,
bool  printFlags = true 
) const

Output a non-list parameter to the given output stream.

The parameter is followed by "[default]" if it is the default value given through a Set method. Otherwise, if the parameter was unused (not accessed through a Get method), it will be followed by "[unused]". This function is called by the "std::ostream& operator<<".
