ProAut Parameter
Introduction
This is a simple helper-package for loading variables from the parameter server.
The main idea is to simplify the handling of parameters, which can be set to default values. The load() function will print if a parameter is loaded from the server or if its default value is used. In each case, the final value is printed, too.
Node
rosrun parameter_pa parameter_pa_node
roslaunch parameter_pa parameter_pa.launch
Services:
| Service Name | Type | Description |
|---|---|---|
| ”~/substitutePath” | parameter_pa/ParameterPaString | Replaces each “$(find xyz)” with the corresponding path - this is similar to calling loadPath(). |
| ”~/substituteRessource” | parameter_pa/ParameterPaString | Resolves ressource name - this is similar to calling loadTopic(). |
Functions
The main load() function can handle bool, int, double and string - all as single values and as vectors. Also matrices of double (float) can be loaded.
Additionaly, there are two more dedicated load functions: loadPath() and loadTopic(). Both are basically loading a simple string from the parameter server as descript above. Furthermore the strings are specificly manipulated:
loadPath()
Every “$(find xyz)” will be replaced with the path of package xyz.
loadTopic()
Names are resolved with additional operators.
For these examples assume that ROS_NAMESPACE is set to “/name/space” and that the nodes’ name is “parameter_pa_node”
