Constructor Detail

MyLeadCreateReplicaImpl

public MyLeadCreateReplicaImpl(org.w3c.dom.Element element)
                        throws uk.org.ogsadai.common.exception.engine.activity.ActivityUserException,
                               uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException
Constructor

Parameters:
element - Element containing Statement conforming to schema for this activity. It is assumed schema checks have been carried out.
Throws:
uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException - If there is a problem constructing the activity due to an implementation error or OGSA-DAI confguration problem.
uk.org.ogsadai.common.exception.engine.activity.ActivityUserException - If there is a problem constructing the activity due to a user mistake such as an invalid setting.
Method Detail

getResult

protected boolean getResult()
                     throws java.sql.SQLException,
                            uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException,
                            uk.org.ogsadai.common.exception.engine.activity.ActivityUserException
This method is called by processBlock, and it processes each replica node in the perform document . It returns either true or false to processBlock. The getResult method must return a boolean value even though it's not used by processBlock in this case. The reason is that getResult is a method in the underlying SQLActivity method.

Overrides:
getResult in class uk.org.ogsadai.activity.sql.SQLActivity
Returns:
boolean indicating if getResult was successful.
Throws:
java.sql.SQLException
uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException
uk.org.ogsadai.common.exception.engine.activity.ActivityUserException

processReplica

protected void processReplica(org.w3c.dom.Node replicaNode)
Process a single replica definition.

Specified by:
processReplica in class MyLeadReplicaActivity
Parameters:
replicaNode - Node from the perform document containing a replica definition.
