def rospy_message_converter.message_converter.convert_dictionary_to_ros_message	(	message_type,
		dictionary
	)

Takes in the message type and a Python dictionary and returns a ROS message.

Example:
    message_type = "std_msgs/String"
    dict_message = { "data": "Hello, Robot" }
    ros_message = convert_dictionary_to_ros_message(message_type, dict_message)

Definition at line 64 of file message_converter.py.

def rospy_message_converter.message_converter.convert_ros_message_to_dictionary ( message )

Takes in a ROS message and returns a Python dictionary.

Example:
    ros_message = std_msgs.msg.String(data="Hello, Robot")
    dict_message = convert_ros_message_to_dictionary(ros_message)

Definition at line 136 of file message_converter.py.

def rospy_message_converter.message_converter.is_ros_binary_type	(	field_type,

Checks if the field is a binary array one, fixed size or not

>>> False
is_ros_binary_type("uint8[]", [42, 18])
>>> True
is_ros_binary_type("uint8[3]", [42, 18, 21]
>>> True

>>> False
is_ros_binary_type("char[]", [42, 18])
>>> True
is_ros_binary_type("char[3]", [42, 18, 21]
>>> True
