public final class TeeFilter
extends AbstractFilterPlugin

This filter has exactly one input port and one output port. A simple message is printed to a configurable stream and all objects are forwarded to the output port.

Constructor Detail

TeeFilter

public TeeFilter(Configuration configuration,
                 IProjectContext projectContext)

Creates a new instance of this class using the given parameters.

Parameters:

configuration - The configuration for this component.

projectContext - The project context for this component.

Method Detail

terminate

public final void terminate(boolean error)

Description copied from class: AbstractFilterPlugin

Initiates a termination of the plugin. This method is only used by the framework and should not be called manually. Use the method AnalysisController.terminate(boolean) instead. After receiving this notification, the plugin should terminate any running methods, e.g., read for readers.

Specified by:

terminate in interface IPlugin

Overrides:

terminate in class AbstractFilterPlugin

Parameters:

error - Determines whether the plugin is terminated due to an error or not.

getCurrentConfiguration

public final Configuration getCurrentConfiguration()

This method should deliver a Configuration object containing the current configuration of this instance. In other words: The constructor should be able to use the given object to initialize a new instance of this class with the same intern properties.

Specified by:

getCurrentConfiguration in interface IAnalysisComponent

Specified by:

getCurrentConfiguration in interface IPlugin

Specified by:

getCurrentConfiguration in class AbstractAnalysisComponent

Returns:

A completely filled configuration object.

inputEvent

public final void inputEvent(Object object)

This method is the input port of the filter receiving incoming objects. Every object will be printed into a stream (based on the configuration) before the filter sends it to the output port.

Parameters:

object - The new object.
