Member Function Documentation

AddrRangeList MemCheckerMonitor::getAddrRanges ( ) const
private
BaseMasterPort & MemCheckerMonitor::getMasterPort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
virtual

Get a master port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic base master port.

Parameters
if_namePort name
idxIndex in the case of a VectorPort
Returns
A reference to the given port

Reimplemented from MemObject.

Definition at line 78 of file mem_checker_monitor.cc.

References MemObject::getMasterPort(), and masterPort.

BaseSlavePort & MemCheckerMonitor::getSlavePort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
virtual

Get a slave port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic base master port.

Parameters
if_namePort name
idxIndex in the case of a VectorPort
Returns
A reference to the given port

Reimplemented from MemObject.

Definition at line 88 of file mem_checker_monitor.cc.

References MemObject::getSlavePort(), and slavePort.

void MemCheckerMonitor::init ( )
virtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

Reimplemented from SimObject.
