Examples of org.pentaho.platform.api.engine.IPluginProvider

org.pentaho.platform.api.engine.IPluginProvider
A plugin provider is responsible for serving up {@link IPlatformPlugin}s to whoever is asking, typically {@link IPluginManager}. The plugin provider is not responsible for integrating the plugins into the platform. It's only role is to render plugin definitions, {@link IPlatformPlugin}s. A plugin provider might load plugin definitions from an xml file, or a properties file. You might also create a plugin provider that creates plugins programmatically. It won't matter what mechanism you use to define your plugins so long as you implement {@link IPluginProvider}. @author aphillips
