Constructor & Destructor Documentation

RTT::PeerParser::PeerParser	(	TaskContext *	c,
		CommonParser &	cp,
		bool	fullpath = `false`
	)

Create a PeerParser which starts looking for peers from a task.

Parameters:

	c	The task to start searching from.
	fullpath	Set to true if the parser() must resolve the full path.

rule_t & RTT::PeerParser::locator ( )

The locator tries to go as far as possible in the peer-to-object path and will never throw. peer() and object() will contain the last valid peer found and its supposed object, attribute or value.

Definition at line 216 of file PeerParser.cpp.

std::string RTT::PeerParser::object ( )

Returns the last matching object name.

Definition at line 231 of file PeerParser.cpp.

rule_t & RTT::PeerParser::parser ( )

The parser tries to traverse a full peer-to-object path and throws if it got stuck in the middle. peer() will return the target peer and object() is this or the supposed object of the peer. The parser does not check if this object exists.

Definition at line 211 of file PeerParser.cpp.

TaskContext * RTT::PeerParser::peer ( )

Returns the last matching peer.

Definition at line 221 of file PeerParser.cpp.

void RTT::PeerParser::reset ( void )

After reset, peer() == current context and object() == "this".
