// DECLARE_ADsDATAARY macros define concrete implementations

//
|
|
// Interface:
|
|
// CADsAry, ~CADsAry
|
|
//
|
|
// EnsureSize Ensures that the array is at least a certain
|
|
// size, allocating more memory if necessary.
|
|
// Note that the array size is measured in elements,
|
|
// rather than in bytes.
|
|
// Size Returns the current size of the array.
|
|
// SetSize Sets the array size; EnsureSize must be called
|
|
// first to reserve space if the array is growing
|
|
//
|
|
// operator LPVOID Allow the CADsAry class to be cast
|
|
// to a (void *)
|
|
//
|
|
// Append Adds a new pointer to the end of the array,
|
|
// growing the array if necessary. Only works
|
|
// for arrays of pointers.
|
|
// AppendIndirect As Append, for non-pointer arrays
|
|
//
|
|
// Insert Inserts a new pointer at the given index in
|
|
// the array, growing the array if necessary. Any
|
|
// elements at or following the index are moved
|
|
// out of the way.
|
|
// InsertIndirect As Insert, for non-pointer arrays
|
|
//
|
|
// Delete Deletes an element of the array, moving any
|
|
// elements that follow it to fill
|
|
// DeleteMultiple Deletes a range of elements from the array,
|
|
// moving to fill
|
|
// BringToFront Moves an element of the array to index 0,
|
|
// shuffling elements to make room
|
|
// SendToBack Moves an element to the end of the array,
|
|
// shuffling elements to make room
|
|
//
|
|
// Find Returns the index at which a given pointer
|
|
// is found
|
|
// FindIndirect As Find, for non-pointer arrays
|
|
//
|
|
// Copy Creates a copy of the object.
|
|
//
|
|
// EnumElements Create an enumerator which supports the given
|
|
// interface ID for the contents of the array
|
|
//
|
|
// EnumElements Create an IEnumVARIANT enumerator.
|
|
//
|
|
//
|
|
// Deref Returns a pointer to an element of the array;
|
|
// normally used by type-safe methods in derived
|
|
// classes
|
|
//
|
|
// GetAlloced Get number of elements allocated
|
|
//
|
|
// Members: _c Current size of the array
|
|
// _pv Buffer storing the elements
|
|
//
|
|
// Note: The CADsAry class only supports arrays of elements
|
|
// whose size is less than CADsAry_MAXELEMSIZE (currently 128).
