Constructor Detail

AbstractGraphFilter

public AbstractGraphFilter(Configuration configuration,
                           IProjectContext projectContext)

Creates a new filter with the given configuration.

Parameters:

configuration - The filter configuration to use

projectContext - The project context to use.

Method Detail

notifyNewIncomingConnection

protected void notifyNewIncomingConnection(java.lang.String inputPortName,
                                           AbstractPlugin connectedPlugin,
                                           java.lang.String outputPortName)
                                    throws AnalysisConfigurationException

Description copied from class: AbstractPlugin

Notification method which is called when a new incoming connection to this plugin is established.

Overrides:

notifyNewIncomingConnection in class AbstractPlugin

Parameters:

inputPortName - The input port name to which the connection was established

connectedPlugin - The plugin that was connected

outputPortName - The opposing plugin's output port from which the connection was established

Throws:

AnalysisConfigurationException - If an error occurs while processing of this notification

init

public boolean init()

Description copied from class: AbstractFilterPlugin

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

Overrides:

init in class AbstractFilterPlugin

Returns:

true on success; false otherwise.

getDesiredOriginRetentionPolicy

protected abstract IOriginRetentionPolicy getDesiredOriginRetentionPolicy()
                                                                   throws AnalysisConfigurationException

Throws:

AnalysisConfigurationException

getCurrentConfiguration

public Configuration getCurrentConfiguration()

Description copied from class: AbstractAnalysisComponent

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.

processGraph

public void processGraph(G graph)

Processes the given graph.

Parameters:

graph - The graph to process

getGraphOutputPortName

public java.lang.String getGraphOutputPortName()

Returns the name of the port this filter uses to emit the graph.

Specified by:

getGraphOutputPortName in interface IGraphOutputtingFilter<G extends AbstractGraph<V,E,O>>

Returns:

See above

getGraphInputPortName

public java.lang.String getGraphInputPortName()

Returns the name of the port this filter accepts graphs on.

Returns:

See above

performConcreteGraphProcessing

protected abstract G performConcreteGraphProcessing(G graph)

This method encapsulates the concrete graph processing performed by the concrete filters.

Parameters:

graph - The graph to process

Returns:

The processed graph, which may be the same as the input graph
