buildId

protected String buildId(DocumentModel doc,
                         RenditionDefinition def)

getTitle

public String getTitle()

Description copied from interface: Work

Gets a human-readable name for this work instance.

Returns:

a human-readable name

getCategory

public String getCategory()

Description copied from interface: Work

Gets the category for this work.

Used to choose an execution queue.

Specified by:

getCategory in interface Work

Overrides:

getCategory in class AbstractWork

Returns:

the category, or null for the default

getTransientStoreName

protected String getTransientStoreName()

work

public void work()

Description copied from interface: Work

This method should implement the actual work done by the Work instance.

It should periodically update its progress through Work.setProgress(org.nuxeo.ecm.core.work.api.Work.Progress).

To allow for suspension by the WorkManager, it should periodically call Work.isSuspending(), and if true call Work.suspended() return early with saved state data.

Clean up can by implemented by #cleanUp().

Specified by:

work in interface Work

Specified by:

work in class AbstractWork

Work.isSuspending(), Work.suspended(), Work.cleanUp(boolean, java.lang.Exception)

cleanUp

public void cleanUp(boolean ok,
                    Exception e)

Description copied from class: AbstractWork

This method is called after AbstractWork.work() is done in a finally block, whether work completed normally or was in error or was interrupted.

Specified by:

cleanUp in interface Work

Overrides:

cleanUp in class AbstractWork

Parameters:

ok - true if the work completed normally

e - the exception, if available

getSourceDocumentModificationDate

protected String getSourceDocumentModificationDate(DocumentModel doc)
