doOnDirectoryCreated

protected void doOnDirectoryCreated(ArchiveEntry entry,
                        java.io.File relativeDir)

Overrides:

doOnDirectoryCreated in class AbstractArchiveExtractor

doOnFileCreating

protected void doOnFileCreating(ArchiveEntry entry)

Description copied from class: AbstractArchiveExtractor

Passes the relative fileName as argument. The absolute name can be constructed if needed like this: new File(getTargetDir(), fileName)

Overrides:

Overrides:

processArchive in class ZipExtractor

Throws:

java.lang.Exception

doOnCancel

protected void doOnCancel()

Description copied from class: AbstractAsyncExecutable

This method is called after having detected cancellation. May be overridden to perform any cleanup. Note that any Exceptions thrown are caught and just logged but do NOT affect the task.

Overrides:

doOnCancel in class AbstractAsyncExecutable

doOnFailure

protected void doOnFailure(java.lang.Exception error)

Description copied from class: AbstractAsyncExecutable

Is called when the task failed. Maybe overridden to perform any cleanup on error. Note that any Exceptions thrown are caught and just logged but do NOT affect the task.

Overrides:
