CWordArray Class
Supports arrays of 16-bit words.
class CWordArray : public CObject
Remarks
The member functions of CWordArray 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 WORD.
CObject* CObArray::GetAt( int <nIndex> ) const;
for example, translates to
WORD CWordArray::GetAt( int <nIndex> ) const;
CWordArray incorporates the IMPLEMENT_SERIAL macro to support serialization and dumping of its elements. If an array of words is stored to an archive, either with an overloaded insertion operator or with the CObject::Serialize member function, each element is, in turn, serialized.
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.
If you need a dump of individual elements in the array, you must set the depth of the dump context to 1 or greater.
For more information on using CWordArray, see the article Collections.
