Detailed Description

This file contains the macros and definitions to create dynamically loadable components. You need to include this header and use one of the macros if you wish to make a run-time loadable component.

Definition in file Component.hpp.

#define ORO_CREATE_COMPONENT ( CLASS_NAME ) namespace { namespace ORO_CONCAT_LINE(LOADER_) { RTT::ComponentFactoryLoader<CLASS_NAME> m_cloader(ORO_LIST_COMPONENT_TYPE_str(CLASS_NAME)); } }

#define ORO_CREATE_COMPONENT_LIBRARY ( ) __attribute__((weak)) RTT::FactoryMap* RTT::ComponentFactories::Factories = 0;

Definition at line 179 of file Component.hpp.

#define ORO_CREATE_COMPONENT_TYPE ( ) ORO_CREATE_COMPONENT_LIBRARY( )

Backwards compatibility macro which is now replaced by ORO_CREATE_COMPONENT_LIBRARY( )

Definition at line 205 of file Component.hpp.

#define ORO_LIST_COMPONENT_TYPE ( CLASS_NAME ) namespace { namespace ORO_CONCAT_LINE(LOADER_) { RTT::ComponentFactoryLoader<CLASS_NAME> m_cloader(ORO_LIST_COMPONENT_TYPE_str(CLASS_NAME)); } }

Use this macro to register multiple components in a shared library (plug-in). For each component, add this line in the .cpp file. Use this macro in combination with ORO_CREATE_COMPONENT_LIBRARY.

The advantage of this approach is that one library can create different component types and that you may link multiple component libraries with each other.

This macro can be used for both shared and static libraries. In case of a shared library, the component factory will be registered to the shared library's local FactoryMap. In case of a static library, the component factory will be registered in the static library's global FactoryMap. In both cases, the DeploymentComponent can access these factories and create the registered component types.

Parameters:

CLASS_NAME the class name of the component you are adding to the library.

Definition at line 100 of file Component.hpp.
