Class NameBearerHandle.ExportApplicationAction.ExporterBuildListener

java.lang.Object
  gate.gui.NameBearerHandle.ExportApplicationAction.ExporterBuildListener

All Implemented Interfaces:

Executable, EventListener, org.apache.tools.ant.BuildListener

Enclosing class:

NameBearerHandle.ExportApplicationAction

 class NameBearerHandle.ExportApplicationAction.ExporterBuildListener
extends Object
implements org.apache.tools.ant.BuildListener, Executable

Build listener to receive log messages from Ant tasks and forward them to the GATE status listener (i.e. the status bar). This class implements Executable not because it is itself executed, but in order to support interruption. If the user presses the stop button in the GUI lock window this object will be interrupted, and will throw an exception at the next call to messageLogged, which has the effect of interrupting the currently executing Ant task.

Method Summary

void	buildFinished(org.apache.tools.ant.BuildEvent buildEvent)
void	buildStarted(org.apache.tools.ant.BuildEvent buildEvent)
void	execute() Starts the execution of this executable
void	interrupt() Notifies this executable that it should stop its execution as soon as possible.
boolean	isInterrupted() Returns true if this executable has been interrupted via the Executable.interrupt() method since the last time its Executable.execute() method was called
void	messageLogged(org.apache.tools.ant.BuildEvent buildEvent) This is called for every log message (of any priority).
void	targetFinished(org.apache.tools.ant.BuildEvent buildEvent)
void	targetStarted(org.apache.tools.ant.BuildEvent buildEvent)
void	taskFinished(org.apache.tools.ant.BuildEvent buildEvent) Set status message appropriately when task completes or fails.

Method Detail

isInterrupted

public boolean isInterrupted()

Description copied from interface: Executable

Returns true if this executable has been interrupted via the Executable.interrupt() method since the last time its Executable.execute() method was called

Specified by:

isInterrupted in interface Executable

interrupt

public void interrupt()

Description copied from interface: Executable

Notifies this executable that it should stop its execution as soon as possible.

Specified by:

interrupt in interface Executable

taskFinished

public void taskFinished(org.apache.tools.ant.BuildEvent buildEvent)

Set status message appropriately when task completes or fails.

Specified by:

taskFinished in interface org.apache.tools.ant.BuildListener

messageLogged

public void messageLogged(org.apache.tools.ant.BuildEvent buildEvent)

This is called for every log message (of any priority). If the current process has been interrupted (the user pressed the stop button) then we throw an exception to interrupt the currently executing Ant task. Other than that, we simply pass INFO and higher messages to the GATE status listener.

Specified by:

messageLogged in interface org.apache.tools.ant.BuildListener

buildStarted

public void buildStarted(org.apache.tools.ant.BuildEvent buildEvent)

Specified by:

buildStarted in interface org.apache.tools.ant.BuildListener

buildFinished

public void buildFinished(org.apache.tools.ant.BuildEvent buildEvent)

Specified by:

buildFinished in interface org.apache.tools.ant.BuildListener

targetStarted

public void targetStarted(org.apache.tools.ant.BuildEvent buildEvent)

Specified by:

targetStarted in interface org.apache.tools.ant.BuildListener

targetFinished

public void targetFinished(org.apache.tools.ant.BuildEvent buildEvent)

Specified by:

targetFinished in interface org.apache.tools.ant.BuildListener

taskStarted

public void taskStarted(org.apache.tools.ant.BuildEvent buildEvent)

Specified by:

taskStarted in interface org.apache.tools.ant.BuildListener

execute

public void execute()

Description copied from interface: Executable

Starts the execution of this executable

Specified by:

execute in interface Executable
