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.
bool getActive | ( | ) |
Returns the active flag associated with this object.
An object is considered "active" if it was rendered in the current frame.

static |
int getDataSizeBytes | ( | ) |
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.
UpdateSeq getModified | ( | ) |
Returns the UpdateSeq that was recorded the last time mark_loaded() was called.
bool getResident | ( | ) |
Returns the resident flag associated with this object.
An object is considered "resident" if it appears to be resident in texture memory.
bool active |
Returns the active flag associated with this object.
An object is considered "active" if it was rendered in the current frame.
int data_size_bytes |
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.
TypedWritableReferenceCount object |
Returns the associated object.
bool resident |
Returns the resident flag associated with this object.
An object is considered "resident" if it appears to be resident in texture memory.
