Bases: BufferContext, AdaptiveLruPage

This is a special class object that holds all the information returned by a particular GSG to indicate the vertex data array’s internal context identifier.

This allows the GSG to cache the vertex data array in whatever way makes sense. For instance, DirectX can allocate a vertex buffer for the array. OpenGL can create a buffer object.

changed_size(reader: GeomPrimitivePipelineReader) → bool

Returns true if the data has changed size since the last time mark_loaded() was called.

changed_usage_hint(reader: GeomPrimitivePipelineReader) → bool

Returns true if the data has changed its usage hint since the last time mark_loaded() was called.

static get_class_type() → TypeHandle

get_data() → GeomPrimitive

Returns the pointer to the client-side array data object.

was_modified(reader: GeomPrimitivePipelineReader) → bool

Returns true if the data has been modified since the last time mark_loaded() was called.
