class_loader
The class_loader package is a ROS-independent package for loading plugins during runtime and the foundation of the higher level ROS pluginlib
library. class_loader utilizes the host operating system’s runtime loader to open runtime libraries (e.g. .so/.dll/dylib files), introspect the library for exported plugin classes, and allows users to instantiate objects of said exported classes without the explicit declaration (i.e. header file) for those classes.
class_loader VS pluginlib
class_loader
is used in the implementation of the higher-level ROS package pluginlib
which is the encouraged method for loading plugins in the ROS ecosystem. You should use class_loader when creating plugins intended for non-ROS packages and pluginlib when exporting plugins to ROS packages.
Quality Declaration
This package claims to be in the Quality Level 1 category, see the Quality Declaration for more details.
Usage
The interface is provided through two classes, class_loader::ClassLoader
and class_loader::MultiLibraryClassLoader
. Both provide similar interfaces but the former only binds to a single runtime library whereas the latter can associate with multiple libraries. The typical workflow is as follows:
- Include
class_loader/class_loader.h
in your source code - Instantiate a
class_loader::ClassLoader
object passing the path and name of the library to open
class_loader::ClassLoader loader("libMyLibrary.so");
- Query the class for exported classes which have an interface defined by some base class (MyBase in the example)
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>()
- Create/destroy objects of said exported classes
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
//'plugin' will automatically be deleted when it goes out of scope
}
- Destroy the ClassLoader object to shutdown the library.
Example: Basic Workflow for ClassLoader
#include <class_loader/class_loader.h>
#include "MyBase.h" //Defines class MyBase
int main()
{
class_loader::ClassLoader loader("libMyLibrary.so");
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>();
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
}
}

class_loader
The class_loader package is a ROS-independent package for loading plugins during runtime and the foundation of the higher level ROS pluginlib
library. class_loader utilizes the host operating system’s runtime loader to open runtime libraries (e.g. .so/.dll/dylib files), introspect the library for exported plugin classes, and allows users to instantiate objects of said exported classes without the explicit declaration (i.e. header file) for those classes.
class_loader VS pluginlib
class_loader
is used in the implementation of the higher-level ROS package pluginlib
which is the encouraged method for loading plugins in the ROS ecosystem. You should use class_loader when creating plugins intended for non-ROS packages and pluginlib when exporting plugins to ROS packages.
Quality Declaration
This package claims to be in the Quality Level 1 category, see the Quality Declaration for more details.
Usage
The interface is provided through two classes, class_loader::ClassLoader
and class_loader::MultiLibraryClassLoader
. Both provide similar interfaces but the former only binds to a single runtime library whereas the latter can associate with multiple libraries. The typical workflow is as follows:
- Include
class_loader/class_loader.h
in your source code - Instantiate a
class_loader::ClassLoader
object passing the path and name of the library to open
class_loader::ClassLoader loader("libMyLibrary.so");
- Query the class for exported classes which have an interface defined by some base class (MyBase in the example)
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>()
- Create/destroy objects of said exported classes
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
//'plugin' will automatically be deleted when it goes out of scope
}
- Destroy the ClassLoader object to shutdown the library.
Example: Basic Workflow for ClassLoader
#include <class_loader/class_loader.h>
#include "MyBase.h" //Defines class MyBase
int main()
{
class_loader::ClassLoader loader("libMyLibrary.so");
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>();
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
}
}
Visit the class_loader API documentation for a complete list of its main components.

0.3.6 (2016-10-24)
- Made changes to two locking mechanisms inside class loader core's loadLibrary() function: 1) I added a lock to the 'addClassLoaderOwnerFor...' function to protect it against a race condition with the unloadLibrary() function. 2) I also raised the loader lock to cover the whole function. Previously the check to see if a library is already loaded and the actual loading of the library was not atomic. Multiple threads could create shared library objects, for example.

class_loader
The class_loader package is a ROS-independent package for loading plugins during runtime and the foundation of the higher level ROS pluginlib
library. class_loader utilizes the host operating system’s runtime loader to open runtime libraries (e.g. .so/.dll/dylib files), introspect the library for exported plugin classes, and allows users to instantiate objects of said exported classes without the explicit declaration (i.e. header file) for those classes.
class_loader VS pluginlib
class_loader
is used in the implementation of the higher-level ROS package pluginlib
which is the encouraged method for loading plugins in the ROS ecosystem. You should use class_loader when creating plugins intended for non-ROS packages and pluginlib when exporting plugins to ROS packages.
Quality Declaration
This package claims to be in the Quality Level 1 category, see the Quality Declaration for more details.
Usage
The interface is provided through two classes, class_loader::ClassLoader
and class_loader::MultiLibraryClassLoader
. Both provide similar interfaces but the former only binds to a single runtime library whereas the latter can associate with multiple libraries. The typical workflow is as follows:
- Include
class_loader/class_loader.h
in your source code - Instantiate a
class_loader::ClassLoader
object passing the path and name of the library to open
class_loader::ClassLoader loader("libMyLibrary.so");
- Query the class for exported classes which have an interface defined by some base class (MyBase in the example)
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>()
- Create/destroy objects of said exported classes
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
//'plugin' will automatically be deleted when it goes out of scope
}
- Destroy the ClassLoader object to shutdown the library.
Example: Basic Workflow for ClassLoader
#include <class_loader/class_loader.h>
#include "MyBase.h" //Defines class MyBase
int main()
{
class_loader::ClassLoader loader("libMyLibrary.so");
std::vector<std::string> classes = loader.getAvailableClasses<MyBase>();
for(unsigned int c = 0; c < classes.size(); ++c)
{
boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
plugin->someMethod();
}
}
Visit the class_loader API documentation for a complete list of its main components.

Changelog for package class_loader
0.3.9 (2018-03-16)
- [bugfix] define PACKAGE_X_DESTINATION to match catkin behavior (#88)
- [migration] Provide alternative headers (#84)
- [style] comply with package format2 xsd (#83) (#85)
- [warnings] c++11 requires at least one argument for ... (#71)
- [style] Use std::string::empty instead comparing with an empty string (#69)
- [style] wrap console bridge invocation lines (#68)
- [copyright] OSRF and not willow in licence header (#67)
- Contributors: David Wagner, Diego Cesar, Mikael Arguedas
0.3.8 (2017-11-16)
- Fix console_bridge marcos definition (#66)
- Style overhaul (#64) (#62)
- Add copyright notice to unique_ptr_test.cpp (#65)
- Contributors: Maarten de Vries, Mikael Arguedas
0.3.7 (2017-07-27)
- switch to package format 2 (#56)
- remove trailing whitespaces (#55)
- use CONSOLE_BRIDGE_X logging macros (#52)
- Contributors: Mikael Arguedas, jmachowinski
0.3.6 (2016-10-24)
- Made changes to two locking mechanisms inside class loader core's loadLibrary() function: 1) I added a lock to the 'addClassLoaderOwnerFor...' function to protect it against a race condition with the unloadLibrary() function. 2) I also raised the loader lock to cover the whole function. Previously the check to see if a library is already loaded and the actual loading of the library was not atomic. Multiple threads could create shared library objects, for example.
- Contributors: Jonathan Meyer
0.3.5 (2016-09-20)
- Add ClassLoader::createUniqueInstance
(#38)
- Wrap comments on createInstance and friend.

- Merge pull request #34 from rhaschke/fix-on-demand-unloading fix on demand unloading
- Merge pull request #32 from saarnold/fixed_unset_variable_evaluation fixed evaluation of undefined variable
- fixed evaluation of undefined variable
- not unloading the ClassLoaders (to avoid the SEVERE WARNING) doesn't work either
- bugfix: enable on-demand loading/unloading with MultiClassLoader
- enforce loading of library in loadLibrary(), otherwise we cannot know
- don't unload libraries in destructor when on-demand-unloading is enabled
- extra utest: MultiClassLoaderTest.lazyLoad succeeds two times in a row?
- added MultiLibraryClassLoader unittest
- Contributors: Mikael Arguedas, Robert Haschke, Sascha Arnold

0.3.8 (2017-11-16)
- Fix console_bridge marcos definition (#66)

- use CONSOLE_BRIDGE_X logging macros (#52)
- Contributors: Mikael Arguedas, jmachowinski
0.3.6 (2016-10-24)
- Made changes to two locking mechanisms inside class loader core's loadLibrary() function: 1) I added a lock to the 'addClassLoaderOwnerFor...' function to protect it against a race condition with the unloadLibrary() function. 2) I also raised the loader lock to cover the whole function. Previously the check to see if a library is already loaded and the actual loading of the library was not atomic. Multiple threads could create shared library objects, for example.
