virtual bool tf2_ros::BufferInterface::canTransform	(	const std::string &	target_frame,
		const std::string &	source_frame,
		const ros::Time &	time,
		const ros::Duration	timeout,
		std::string *	errstr = NULL
	)		const [pure virtual]

Test if a transform is possible.

Parameters:

target_frame	The frame into which to transform
source_frame	The frame from which to transform
time	The time at which to transform
timeout	How long to block before failing
errstr	A pointer to a string which will be filled with why the transform failed, if not NULL

Returns:

True if the transform is possible, false otherwise

Implemented in tf2_ros::Buffer, and tf2_ros::BufferClient.

		const ros::Time &	target_time,
		const std::string &	source_frame,
		const ros::Time &	source_time,
		const std::string &	fixed_frame,
		const ros::Duration	timeout,
		std::string *	errstr = NULL
	)		const [pure virtual]

Test if a transform is possible.

Parameters:

target_frame	The frame into which to transform
target_time	The time into which to transform
source_frame	The frame from which to transform
source_time	The time from which to transform
fixed_frame	The frame in which to treat the transform as constant in time
timeout	How long to block before failing
errstr	A pointer to a string which will be filled with why the transform failed, if not NULL

Returns:

True if the transform is possible, false otherwise

Implemented in tf2_ros::Buffer, and tf2_ros::BufferClient.

		const std::string &	source_frame,
		const ros::Time &	time,
		const ros::Duration	timeout
	)		const [pure virtual]

Get the transform between two frames by frame ID.

Parameters:

target_frame	The frame to which data should be transformed
source_frame	The frame where the data originated
time	The time at which the value of the transform is desired. (0 will get the latest)
timeout	How long to block before failing

Returns:

The transform between the frames

Possible exceptions tf2::LookupException, tf2::ConnectivityException, tf2::ExtrapolationException, tf2::InvalidArgumentException

Implemented in tf2_ros::Buffer, and tf2_ros::BufferClient.

virtual geometry_msgs::TransformStamped tf2_ros::BufferInterface::lookupTransform	(	const std::string &	target_frame,
		const ros::Time &	target_time,
		const std::string &	source_frame,
		const ros::Time &	source_time,
		const std::string &	fixed_frame,
		const ros::Duration	timeout
	)		const [pure virtual]

Get the transform between two frames by frame ID assuming fixed frame.

Parameters:

target_frame	The frame to which data should be transformed
target_time	The time to which the data should be transformed. (0 will get the latest)
source_frame	The frame where the data originated
source_time	The time at which the source_frame should be evaluated. (0 will get the latest)
fixed_frame	The frame in which to assume the transform is constant in time.
timeout	How long to block before failing

Returns:

The transform between the frames

Possible exceptions tf2::LookupException, tf2::ConnectivityException, tf2::ExtrapolationException, tf2::InvalidArgumentException

Implemented in tf2_ros::Buffer, and tf2_ros::BufferClient.
