Package roshlaunch :: Module core

Module core

Core roslaunch model and lower-level utility routines.

Classes
	RLException Base roslaunch exception type
	Master Data structure for representing and querying state of master
	Machine Data structure for storing information about a machine in the ROS system.
	Param Data structure for storing information about a desired parameter in the ROS system Corresponds to the 'param' tag in the launch specification.
	Node Data structure for storing information about a desired node in the ROS system Corresponds to the 'node' tag in the launch specification.
	Test A Test is a Node with special semantics that it performs a unit/integration test.
	Executable Executable is a generic container for exectuable commands.
	RosbinExecutable RosbinExecutables are exectuables stored in ROS_ROOT/bin.
