Class Recorder

java.lang.Object
  org.apache.tools.ant.ProjectComponent
      org.apache.tools.ant.Task
          org.apache.tools.ant.taskdefs.Recorder

All Implemented Interfaces:: java.lang.Cloneable, java.util.EventListener, BuildListener, SubBuildListener

public class Recorder
extends Task
implements SubBuildListener
extends Task
implements SubBuildListener

Adds a listener to the current build process that records the output to a file.

Several recorders can exist at the same time. Each recorder is associated with a file. The filename is used as a unique identifier for the recorders. The first call to the recorder task with an unused filename will create a recorder (using the parameters provided) and add it to the listeners of the build. All subsequent calls to the recorder task using this filename will modify that recorders state (recording or not) or other properties (like logging level).

Some technical issues: the file's print stream is flushed for "finished" events (buildFinished, targetFinished and taskFinished), and is closed on a buildFinished event.

Since:: Ant 1.4
Version:: 0.5

public Recorder()

Method Detail

init

public void init()

Overridden so we can add the task as build listener.

Overrides:: init in class Task

Since:: Ant 1.7

setName

public void setName(java.lang.String fname)

Sets the name of the file to log to, and the name of the recorder entry.

Parameters:: fname - File name of logfile.

setAction

public void setAction(Recorder.ActionChoices action)

Sets the action for the associated recorder entry.

Parameters:: action - The action for the entry to take: start or stop.

setAppend

public void setAppend(boolean append)

Whether or not the logger should append to a previous file.

Parameters:: append - if true, append to a previous file.

setEmacsMode

public void setEmacsMode(boolean emacsMode)

Set emacs mode.

Parameters:: emacsMode - if true use emacs mode

setLoglevel

public void setLoglevel(Recorder.VerbosityLevelChoices level)

Sets the level to which this recorder entry should log to.

Parameters:: level - the level to set.
See Also:: Recorder.VerbosityLevelChoices

execute

public void execute()
             throws BuildException

The main execution.

Overrides:: execute in class Task

Throws:: BuildException - on error

getRecorder

protected RecorderEntry getRecorder(java.lang.String name,
                                    Project proj)
                             throws BuildException

Gets the recorder that's associated with the passed in name. If the recorder doesn't exist, then a new one is created.

Parameters:: name - the name of the recoder; proj - the current project
Returns:: a recorder
Throws:: BuildException - on error
