Class EPPHostHandler

java.lang.Object

com.verisign.epp.framework.EPPHostHandler

All Implemented Interfaces:

EPPEventHandler

Direct Known Subclasses:

HostHandler

public abstract class EPPHostHandler
extends java.lang.Object
implements EPPEventHandler

The EPPHostHandler class provides an interface for handling Host EPP Commands in a Server implementation. EPPEvents are handled by the handleEvent() method here and routed to the appropriate abstract member function. Subclasses should override the abstract methods to define the desired behavior of a particular command when it is received. A subclassed instance of EPPHostHandler should be registered with the EPPDispatcher so that EEPEvents related to the Host Mapping will be handled there.

Method Detail

getNamespace

public final java.lang.String getNamespace()

Returns the Namespace that this handler supports. In this case, host.

Specified by:

getNamespace in interface EPPEventHandler

Returns:

String The Namespace that this handler supports

handleEvent

public final EPPEventResponse handleEvent(EPPEvent aEvent,
                                          java.lang.Object aData)
                                   throws EPPEventException

This method receives an EPPEvent and routes it to the appropriate abstract method.

Specified by:

handleEvent in interface EPPEventHandler

Parameters:

aEvent - An EPPEvent that contains the EPPCommand

aData - Any data that a Server needs to send to this EPPContactHandler instance

Returns:

DOCUMENT ME!

Throws:

EPPEventException - Thrown if an unrecognized EPPEvent is received

preHandleEvent

protected void preHandleEvent(EPPEvent aEvent,
                              java.lang.Object aData)
                       throws EPPHandleEventException

Handles any common behavior that all host commands need to execute before they execute their command specific behavior. The default implementation does nothing.

Parameters:

aEvent - The EPPEvent that is being handled

aData - Any data that a Server needs to send to this EPPDomainHandler

Throws:

EPPHandleEventException - Thrown if an error condition occurs. It must contain an EPPEventResponse

postHandleEvent

protected void postHandleEvent(EPPEvent aEvent,
                               java.lang.Object aData)
                        throws EPPHandleEventException

Handles any common behavior that all gen commands need to execute after they execute their command specific behavior. The default implementation does nothing

Parameters:

aEvent - The EPPEvent that is being handled

aData - Any data that a Server needs to send to this EPPDomainHandler

Throws:

EPPHandleEventException - Thrown if an error condition occurs. It must contain an EPPEventResponse

doHostCreate

protected abstract EPPEventResponse doHostCreate(EPPEvent aEvent,
                                                 java.lang.Object aData)

Invoked when a Host Create command is received. Subclasses should define the behavior when a Host Create command is received.

Parameters:

aEvent - The EPPEvent that is being handled
