◆ isSnooping()
|
inlinevirtual |
Determine if this request port is snooping or not.
The default implementation returns false and thus tells the neighbour we are not snooping. Any request port that wants to receive snoop requests (e.g. a cache connected to a bus) has to override this function.
- Returns
- true if the port should be considered a snooper
Reimplemented from RequestPort.
