Constructor Detail

SimilarityTask

public SimilarityTask()

Method Detail

getDescription

public String getDescription()

Description copied from class: Task

HTML or plain text description of this task.

Overrides:

getDescription in class Task

Returns:

description

getName

public String getName()

Description copied from class: Task

HTML or plaintext name of this task. Defaults to the task's classname.

Overrides:

getName in class Task

Returns:

name

createPipeline

public SignalProcessor createPipeline(AudioFileFormat audioFileFormat)

Overrides:

createPipeline in class AudioAnalysisTask

isReplaceExistingValue

public boolean isReplaceExistingValue()

setReplaceExistingValue

public void setReplaceExistingValue(boolean replaceExistingValue)

processBefore

public void processBefore(Task task)

Description copied from class: Task

Process online results with this task before other tasks are invoked. Override this method, if you want to take online resources into account. Note that you will also need to set Task.setUseOnlineResources(boolean) to true, if you want this method to be called at all.

To avoid having this task processed again by Task.runBefore(Task), you must call Task.setSucceeded(boolean) with the argument true. If, for some reason, you could not take care of this task with just the available online resources, you must call Task.setSucceeded(boolean) with the argument false

This method is executed before sub tasks are run. When this method is called, the methods Task.getSong() and Task.getReferenceSong() will return meaningful results.

Specified by:

processBefore in interface TaskProcessListener

Overrides:

processBefore in class Task

Parameters:

task - task

runBefore

public void runBefore(Task task)
               throws AnalysisException

Description copied from class: Task

Is executed before sub tasks are run.

Specified by:

runBefore in interface TaskRunListener

Overrides:

runBefore in class Task

Parameters:

task - task

Throws:

AnalysisException - if this analysis step fails

skip

public boolean skip()

Description copied from class: Task

Indicates, whether this task can be skipped. Defaults to false.

Since this task is not necessarily called by beaTunes, but by your own implementation of Task.runBefore(Task), you should call Task.setSkipped(boolean) with whatever value you are returning.

Overrides:

skip in class Task

Returns:

true or false

createDeepCopy

public Task createDeepCopy()

Description copied from class: Task

This method creates a copy of the Task and its subtasks. If you added any members to your subclass you MUST override this method and provide code that copies your members.

Overrides:

createDeepCopy in class Task

Returns:

copy

equals

public boolean equals(Object o)

Overrides:

equals in class Task

toString

public String toString()

Overrides:

toString in class Task
