CPtrArray Class

class CPtrArray : public CObject


The CPtrArray class supports arrays of void pointers.

The member functions of CPtrArray are similar to the member functions of class CObArray. Because of this similarity, you can use the CObArray reference documentation for member function specifics. Wherever you see a CObject pointer as a function parameter or return value, substitute a pointer to void.

CObject* CObArray::GetAt( int <nIndex> ) const;

for example, translates to

void* CPtrArray::GetAt( int <nIndex> ) const;

CPtrArray incorporates the IMPLEMENT_DYNAMIC macro to support run-time type access and dumping to a CDumpContext object. If you need a dump of individual pointer array elements, you must set the depth of the dump context to 1 or greater.

Note   Before using an array, use SetSize to establish its size and allocate memory for it. If you do not use SetSize, adding elements to your array causes it to be frequently reallocated and copied. Frequent reallocation and copying are inefficient and can fragment memory.

Pointer arrays cannot be serialized.

When a pointer array is deleted, or when its elements are removed, only the pointers are removed, not the entities they reference.

For more information on using CPtrArray, see the article Collections.
