Detailed Description

The Command class represents some action that needs to be performed on one or more memory objects.

The Command has a vector of DepDesc objects that represent dependencies of the command. It has a vector of pointers to commands that depend on the command. It has a pointer to a queue object and an event that is associated with the command.

Creates an edge event when the dependency is a command.

Method takes in void * for the address as adding a template function to the command group object maybe undesirable.

Parameters
CmdThe command object of the source of the edge
ObjAddrThe address that defines the edge dependency; it is the event address when the edge is for an event and a memory object address if it is due to an accessor
PrefixContains "event" if the dependency is an edge and contains the access mode to the buffer if it is due to an accessor
IsCommandTrue if the dependency has a command object as the source, false otherwise
