Detailed Description

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.

Member Function Documentation

◆ get_next()

BufferContext * BufferContext::get_next ( ) const

inline

This can be used along with BufferContextChain::get_first() to walk through the list of objects stored on a tracker.

Definition at line 95 of file bufferContext.I.

◆ set_active()

void BufferContext::set_active ( bool flag )

inline

Changes the active flag associated with this object.

An object is considered "active" if it was rendered in the current frame.

Definition at line 65 of file bufferContext.I.

◆ set_resident()

void BufferContext::set_resident ( bool flag )

inline

Changes the resident flag associated with this object.

An object is considered "resident" if it appears to be resident in texture memory.

Definition at line 81 of file bufferContext.I.

Referenced by TextureContext::mark_loaded(), TextureContext::mark_simple_loaded(), IndexBufferContext::mark_unloaded(), VertexBufferContext::mark_unloaded(), and TextureContext::mark_unloaded().

◆ update_data_size_bytes()

void BufferContext::update_data_size_bytes ( size_t new_data_size_bytes )

inline

Should be called (usually by a derived class) when the on-card size of this object has changed.

Definition at line 108 of file bufferContext.I.

Referenced by IndexBufferContext::update_data_size_bytes(), VertexBufferContext::update_data_size_bytes(), and TextureContext::update_data_size_bytes().

◆ update_modified()

void BufferContext::update_modified ( UpdateSeq new_modified )

inline

Should be called (usually by a derived class) when the modified counter for this object has changed.

Definition at line 120 of file bufferContext.I.

Referenced by TextureContext::mark_loaded(), TextureContext::mark_simple_loaded(), IndexBufferContext::mark_unloaded(), VertexBufferContext::mark_unloaded(), and TextureContext::mark_unloaded().

Member Data Documentation

◆ get_active

bool BufferContext::get_active

inline

Returns the active flag associated with this object.

An object is considered "active" if it was rendered in the current frame.

Definition at line 55 of file bufferContext.h.

Referenced by Texture::get_active().

◆ get_data_size_bytes

size_t BufferContext::get_data_size_bytes

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.

Definition at line 53 of file bufferContext.h.

Referenced by Texture::get_data_size_bytes().

◆ get_modified

UpdateSeq BufferContext::get_modified

inline

Returns the UpdateSeq that was recorded the last time mark_loaded() was called.

Definition at line 54 of file bufferContext.h.

◆ get_object

TypedWritableReferenceCount * BufferContext::get_object

inline

Returns the associated object.

Definition at line 51 of file bufferContext.h.

◆ get_resident

bool BufferContext::get_resident

inline

Returns the resident flag associated with this object.

An object is considered "resident" if it appears to be resident in texture memory.

Definition at line 56 of file bufferContext.h.

Referenced by Texture::get_resident().
