• ContextObjChain ** d_restoreChainPrev

  Pointer to the pointer of the previous object which points to us. This makes a doubly-linked list for easy element deletion.
  

• ContextObjChain * d_restore

  Pointer to the previous copy which belongs to the same master.
  

• ContextObj * d_data

  Pointer to copy of master to be restored when restore() is called.

Detailed Description

Description: An element of a doubly linked list holding a copy of ContextObj in a scope. It is made separate from ContextObj to keep the list pointers valid in all scopes at all times, so that the object can be easily removed from the list when the master ContextObj is destroyed.

Definition at line 120 of file context.h.
