Member Function Documentation

◆ Allocate()

virtual VERTEX * KIGFX::VERTEX_CONTAINER::Allocate ( unsigned int  aSize)
pure virtual

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
aSizeis the number of vertices to be allocated.
Returns
Pointer to the allocated space or NULL in case of failure.

Implemented in KIGFX::CACHED_CONTAINER, and KIGFX::NONCACHED_CONTAINER.

◆ Clear()

virtual void KIGFX::VERTEX_CONTAINER::Clear ( )
pure virtual

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

Implemented in KIGFX::CACHED_CONTAINER, and KIGFX::NONCACHED_CONTAINER.

Referenced by KIGFX::GPU_NONCACHED_MANAGER::EndDrawing().

◆ ClearDirty()

void KIGFX::VERTEX_CONTAINER::ClearDirty ( )
inline

Clear the dirty flag to prevent reuploading vertices to the GPU memory.

Definition at line 152 of file vertex_container.h.

◆ Delete()

virtual void KIGFX::VERTEX_CONTAINER::Delete ( VERTEX_ITEM aItem)
pure virtual

Erase the data related to an item.

Parameters
aItemis the item to be erased.

Implemented in KIGFX::CACHED_CONTAINER, and KIGFX::NONCACHED_CONTAINER.

◆ FinishItem()

virtual void KIGFX::VERTEX_CONTAINER::FinishItem ( )
inlinevirtual

Clean up after adding an item.

Reimplemented in KIGFX::CACHED_CONTAINER.

Definition at line 78 of file vertex_container.h.

◆ GetAllVertices()

VERTEX * KIGFX::VERTEX_CONTAINER::GetAllVertices ( ) const
inline

Return pointer to the vertices stored in the container.
