RTT::detail::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::detail::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.

rule_t& RTT::detail::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.
