Method Details

supportsQueryFilterInput

public boolean supportsQueryFilterInput()

Description copied from interface: DeleteInterface

Specify whether this particular module's delete action natively supports receiving a queryFilter as input (e.g., SQL does). If the module doesn't support a query filter, then the qqq framework (DeleteAction) will, if it receives a queryFilter in its input, it will execute the query, and pass the list of primary keys down into the module's delete implementation.

Specified by:

supportsQueryFilterInput in interface DeleteInterface
