niryo_libraries.rospy.rostime

module documentation

ROS time and duration representations, as well as internal routines for managing wallclock versus a simulated clock. The important data classes are L{Time} and L{Duration}, which represent the ROS 'time' and 'duration' primitives, respectively.

Function get_rostime_cond internal API for helper routines that need to wait on time updates @return: rostime conditional var @rtype: threading.Cond
Function is_rostime_initialized Internal use. @return: True if rostime has been initialized @rtype: bool
Function is_wallclock Internal use for ROS-time routines. @return: True if ROS is currently using wallclock time @rtype: bool
Function set_rostime_initialized Internal use. Mark rostime as initialized. This flag enables other routines to throw exceptions if rostime is being used before the underlying system is initialized. @param val: value for initialization state @type val: bool...
Function switch_to_wallclock Internal use. Switch ROS to wallclock time. This is mainly for testing purposes.
Function wallsleep Internal use. Windows interrupts time.sleep with an IOError exception when a signal is caught. Even when the signal is handled by a callback, it will then proceed to throw IOError when the handling has completed.
Function _set_rostime Callback to update ROS time from a ROS Topic
Variable _rostime_cond Undocumented
Variable _rostime_current Undocumented
Variable _rostime_initialized Undocumented

internal API for helper routines that need to wait on time updates @return: rostime conditional var @rtype: threading.Cond

def is_rostime_initialized():

Internal use. @return: True if rostime has been initialized @rtype: bool

def is_wallclock():

Internal use for ROS-time routines. @return: True if ROS is currently using wallclock time @rtype: bool

def set_rostime_initialized(val):

Internal use. Mark rostime as initialized. This flag enables other routines to throw exceptions if rostime is being used before the underlying system is initialized. @param val: value for initialization state @type val: bool

def switch_to_wallclock():

Internal use. Switch ROS to wallclock time. This is mainly for testing purposes.

def wallsleep(duration):

Internal use. Windows interrupts time.sleep with an IOError exception when a signal is caught. Even when the signal is handled by a callback, it will then proceed to throw IOError when the handling has completed.

Refer to https://code.ros.org/trac/ros/ticket/3421.

So we create a platform dependant wrapper to handle this here.
