Constructor Detail

AbstractReaderPlugin

public AbstractReaderPlugin(Configuration configuration,
                            IProjectContext projectContext)

Each Plugin requires a constructor with a Configuration object and a IProjectContext.

Parameters:

configuration - The configuration for this component.

projectContext - The project context for this component. The component will be registered.

Method Detail

init

public boolean init()

Initiates the start of a component. This method is called once when a AnalysisController's run() method is called. This implementation must not be blocking! Asynchronous consumers would spawn (an) asynchronous thread(s) in this method.

Specified by:

init in interface IPlugin

Returns:

true on success; false otherwise.
