Constructor & Destructor Documentation

◆ NONCACHED_CONTAINER()

NONCACHED_CONTAINER::NONCACHED_CONTAINER ( unsigned int aSize = DEFAULT_SIZE )

Construct a non-cached container object.

Parameters

aSize is the size of the cache.

Exceptions

bad_alloc exception if memory allocation fails.

Member Function Documentation

◆ Abandon()

virtual void KIGFX::VERTEX_CONTAINER::Abandon ( )

inlinevirtualinherited

Give up ownership of any GL objects without deleting them.

Used when the owning context can no longer be made current, so a delete would be executed against whichever context is, possibly one from another share group. The names are released when the owning context is destroyed.

Reimplemented in KIGFX::CACHED_CONTAINER_GPU.

Definition at line 61 of file vertex_container.h.

◆ Allocate()

VERTEX * NONCACHED_CONTAINER::Allocate ( unsigned int aSize )

overridevirtual

Return allocated space for the requested number of vertices associated with the current item (set with SetItem()).

The allocated space is added at the end of the chunk used by the current item and may serve to store new vertices.

Parameters

aSize is the number of vertices to be allocated.

Returns: Pointer to the allocated space or NULL in case of failure.

Implements KIGFX::VERTEX_CONTAINER.

◆ Clear()

void NONCACHED_CONTAINER::Clear ( )

overridevirtual

Remove all data stored in the container and restores its original state.
