This class is designed to be used as a substitute for array arguments to functions. It aggregates a pointer to a contiguous array of data and the size of that array. In debug mode, it will perform runtime checks of all usage.
The ArrayView class has the same shallow copy semantics of the # Ptr class. ArrayView is to ArrayRCP as Ptr is to RCP.

| Teuchos::ArrayView< T >::ArrayView | ( | const ArrayView< T > & | array | ) | [inline] |
Initialize from another ArrayView<T> object.
After construction, this and array 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.

| void Teuchos::ArrayView< T >::assign | ( | const ArrayView< const T > & | array | ) | const |
Copy the data from one array view object to this array view object.
Preconditions:

WARNING! If T is a const type (e.g. const double) then do not try to instantiate this function since it will not compile!
NOTE: This function is really like an operator=() function except that it is declared const. This is the correct behavior since a const ArrayView simply means that we can not change what *this points to. The type of the template argument always determines if the underlyihng data is const or not.

| ArrayView< T >::iterator Teuchos::ArrayView< T >::begin | ( | ) | const |
Return an iterator to beginning of the array of data.

Output stream inserter.
The implementation of this function just prints pointer addresses and therefore puts no restrictions on the data types involved.
Definition at line 401 of file Teuchos_ArrayView.hpp.
Reinterpret cast of underlying ArrayView 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.
