CObList::RemoveTail

  • 项目

CObject*RemoveTail();

Return Value

A pointer to the object that was at the tail of the list.

Remarks

Removes the element from the tail of the list and returns a pointer to it.

You must ensure that the list is not empty before calling RemoveTail. If the list is empty, then the Debug version of the Microsoft Foundation Class Library asserts. Use IsEmpty to verify that the list contains elements.

Example

See CObList::CObList for a listing of the CAge class.

list;
CAge* pa1;
CAge* pa2;

list.AddHead( pa1 = new CAge( 21 ) );
list.AddHead( pa2 = new CAge( 40 ) ); // List now contains (40, 21).
ASSERT( *(CAge*) list.RemoveTail() == CAge( 21 ) );  // Old tail
ASSERT( *(CAge*) list.GetTail() == CAge( 40 ) );  // New tail
delete pa1;
delete pa2; // Clean up memory.
