Configurable tf2 client wrapper switching between local and remote buffer.

Usage

rospy.init_node('awesome_node')
buffer = tf2_client.get_buffer()
buffer.lookup_transform(target_frame, source_frame, time)

Parameters

• For remote buffer (parameters of tf2_ros.BufferClient):
  • ~tf_server, defaults to None
  • ~tf_check_frequency, None
  • ~tf_timeout_padding, 2.0
• For local buffer (parameters of tf2_ros.Buffer and tf2_ros.TransformListener):
  • ~tf_cache_time, 10.0
  • ~tf_queue_size, None
  • ~tf_buff_size, 65536

Remote buffer is used if parameter ~tf_server is specified.
