Method Detail

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

getTitle

public String getTitle()

Description copied from interface: Work

Gets a human-readable name for this work instance.

Returns:

a human-readable name

isIdempotent

public boolean isIdempotent()

Description copied from interface: Work

Returns true if a work with a given Work.getId() should always produce the same result. The WorkManager implementation can safely skip duplicate executions of idempotent work.

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 Work.cleanUp(boolean, Exception).

Specified by:

work in interface Work

Specified by:

work in class AbstractWork
