// Class : dallocator
|
|
// Description : This is similar to pallocator, but always uses the
|
|
// default new and delete handlers defined in
|
|
// dtoolbase_cc.h; it never calls the hooks assigned by
|
|
// redefining global_operator_new, etc.
|
|
//
|
|
// This is needed in those rare cases when we need to
|
|
// allocate memory for STL without going through the
|
|
// callback hooks, for instance to implement STL tables
|
|
// within the MemoryUsage class itself.
