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.

void RTT::PeerParser::done ( )

private

Definition at line 70 of file PeerParser.cpp.

bool RTT::PeerParser::foundPath

(

)

Returns true if the PeerParser found a valid path. Will also return true if fullpath was set to false in the constructor and a partial match was made.

Definition at line 240 of file PeerParser.cpp.

error_status RTT::PeerParser::handle_no_peer ( scanner_t const &  scan, parser_error< PeerErrors, iter_t > &  e  )

private

void RTT::PeerParser::locatepeer ( iter_t  begin, iter_t  end  )

private

Definition at line 170 of file PeerParser.cpp.

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 220 of file PeerParser.cpp.

std::string RTT::PeerParser::object

(

)

Returns the last matching object name.

Definition at line 235 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 215 of file PeerParser.cpp.

TaskContext * RTT::PeerParser::peer

(

)

Returns the last matching peer.

Definition at line 225 of file PeerParser.cpp.

void RTT::PeerParser::reset

(

)

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

Definition at line 151 of file PeerParser.cpp.

void RTT::PeerParser::seenobjectname ( iter_t  begin, iter_t  end  )

private

Definition at line 162 of file PeerParser.cpp.

Service::shared_ptr RTT::PeerParser::taskObject

(

)

Returns the last matching Service or zero if not found.

Definition at line 230 of file PeerParser.cpp.
