Public Member Functions | |
int | get_count () const |
Returns the total number of BufferContexts currently assigned to this tracker. | |
BufferContext * | get_first () |
Returns the first BufferContext object stored in the tracker. | |
size_t | get_total_size () const |
Returns the total number of bytes represented by the BufferContexts currently assigned to this tracker. | |
void | take_from (BufferContextChain &other) |
Moves all of the BufferContexts from the other tracker onto this one. | |
void | write (ostream &out, int indent_level) const |
Private Member Functions | |
void | insert_after (LinkedListNode *node) |
Adds a LinkedListNode record after the indicated node in the doubly-linked list. | |
void | insert_before (LinkedListNode *node) |
Adds a LinkedListNode record before the indicated node in the doubly-linked list. | |
bool | is_on_list () const |
Returns true if the node is member of any list, false if it has been removed or never added. | |
void | remove_from_list () |
Removes a LinkedListNode record from the doubly-linked list. | |
void | take_list_from (LinkedListNode *other_root) |
Given that this LinkedListNode represents the root of a list, and the other pointer represents the root of a different list, move all of the nodes (except the root itself) from other_root onto this list. | |

class | BufferContext |
This class maintains a linked list of BufferContexts that might be allocated on the graphics card in some context.
There is a different BufferContextChain for resident textures, active textures, evicted textures, etc.
The primary purpose of this class is to facilitate PStats reporting of graphics memory usage.

int BufferContextChain::get_count | ( | ) | const [inline] |
Returns the total number of BufferContexts currently assigned to this tracker.
Definition at line 57 of file bufferContextChain.I.
BufferContext * BufferContextChain::get_first | ( | ) |
Returns the first BufferContext object stored in the tracker.
You can walk through the entire list of objects stored on the tracker by calling get_next() on each returned object, until the return value is NULL.

size_t BufferContextChain::get_total_size | ( | ) | const [inline] |
Returns the total number of bytes represented by the BufferContexts currently assigned to this tracker.
Definition at line 46 of file bufferContextChain.I.
void BufferContextChain::take_from | ( | BufferContextChain & | other | ) |
Moves all of the BufferContexts from the other tracker onto this one.
