// Class : PipelineCyclerLinks
|
|
// Description : This just stores the pointers to implement a
|
|
// doubly-linked list of PipelineCyclers for a
|
|
// particular Pipeline object. We use a hand-rolled
|
|
// linked list rather than any STL container, because we
|
|
// want PipelineCyclers to be able to add and remove
|
|
// themselves from this list very quickly.
|
|
//
|
|
// These pointers are inherited from this separate class
|
|
// so the Pipeline object itself can be the root of the
|
|
// linked list.
