This is a base class for those kinds of SavedContexts that occupy an easily-measured (and substantial) number of bytes in the video card's frame buffer memory or AGP memory.
At the present, this includes most of the SavedContext types: VertexBufferContext and IndexBufferContext, as well as TextureContext.
This class provides methods for tracking the video memory utilization, as well as residency of each object, via PStats.

Returns the active flag associated with this object.
An object is considered "active" if it was rendered in the current frame.
Definition at line 49 of file bufferContext.I.
Referenced by Texture::get_active().
|
inline |
Returns the number of bytes previously reported for the data object.
This is used to track changes in the data object's allocated size; if it changes from this, we need to create a new buffer. This is also used to track memory utilization in PStats.
