		const std::vector< double > &	joint_angles,
		std::vector< geometry_msgs::Pose > &	poses
	)		const `[virtual]`

Given a set of joint angles and a set of links, compute their pose.

This FK routine is only used if 'use_plugin_fk' is set in the 'arm_kinematics_constraint_aware' node, otherwise ROS TF is used to calculate the forward kinematics

Parameters:

link_names	A set of links for which FK needs to be computed
joint_angles	The state for which FK is being computed
poses	The resultant set of poses (in the frame returned by getBaseFrame())

Returns:: True if a valid solution was found, false otherwise

Implements kinematics::KinematicsBase.

		moveit_msgs::MoveItErrorCodes &	error_code,
		bool	lock_redundant_joints = `false`
	)		const

Given a desired pose of the end-effector, compute the joint angles to reach it.

Parameters:

ik_pose	the desired pose of the link
ik_seed_state	an initial guess solution for the inverse kinematics
solution	the solution vector
error_code	an error code that encodes the reason for failure or success
lock_redundant_joints	?
