oracle.dmt.jdm.base
Class OraTask

java.lang.Object
oracle.dmt.jdm.OraDMObject
oracle.dmt.jdm.OraMiningObject
oracle.dmt.jdm.base.OraTask

All Implemented Interfaces:

javax.datamining.MiningObject, oracle.dmt.jdm.OraPLSQLConstants, javax.datamining.base.Task

Direct Known Subclasses:

oracle.dmt.jdm.task.apply.OraApplyTask, OraBuildTask, OraTestTask

public abstract class OraTask

extends oracle.dmt.jdm.OraMiningObject

implements javax.datamining.base.Task

The class OraTask add new extension methods in 11.1 to javax.datamining.base.Task. These methods allows to specify task dependencies and thus enable execution of tasks as a sequence of tasks that allows to specify processes, such as model build --> test --> apply. Without this feature, client applications have to wait for the completion of the dependent tasks using either ExecutionHandle.waitForCompletion method or periodic polling the server by using ExecutionHandle.getLatestStatus method.

Since:

OJDM 11.1.0
