Constructor Detail

PipeReader

public PipeReader(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

read

public boolean read()

Blocks until the associated pipe is being closed.

Specified by:

read in interface IReaderPlugin

Returns:

true if the reading terminated in a "normal" way. If an interrupt terminates the wait-method too early, false will be returned.

newMonitoringRecord

public boolean newMonitoringRecord(IMonitoringRecord rec)

This method sends a given records directly to the output port.

Specified by:

newMonitoringRecord in interface IPipeReader

Parameters:

rec - The new record object.

Returns:

true if and only if the record has been delivered.

notifyPipeClosed

public void notifyPipeClosed()

Called to notify the reader that the pipe is closed.

Specified by:

notifyPipeClosed in interface IPipeReader

terminate

public void terminate(boolean error)

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

Parameters:

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

getCurrentConfiguration

public 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.
