Instance Method Details

#from_ros(typekit, buffer, indent) ⇒ Object

Convert a C++ value into the corresponding ROS value The C++ value is called 'value' and is a ref to the C++ type. The ROS value is called 'ros' and is a const-ref.

The method must return the string that will be used for convertion
