Class ConditionalSoftDeleteDbRowOpFactory

java.lang.Object

org.apache.cayenne.access.flush.operation.ConditionalSoftDeleteDbRowOpFactory

All Implemented Interfaces:

DeleteDbRowOpFactory

public class ConditionalSoftDeleteDbRowOpFactory
extends Object
implements DeleteDbRowOpFactory

A DeleteDbRowOpFactory enabling "soft delete". For tables that contain a BOOLEAN column with the configured name it produces SoftDeleteDbRowOp, so the row is deleted by an UPDATE setting that column to true. Tables without such a column (or whose column of that name is not BOOLEAN) get a plain DeleteDbRowOp and are deleted with a regular SQL DELETE.
