public static EPPDispatcher getInstance()

Gets the one and only instance of the EPPDispatcher

Returns:

Dispatcher The dispatcher

processConnection

public void processConnection(java.io.InputStream aInputStream,
                              java.io.OutputStream aOutputStream,
                              java.lang.Object aData)

Returns the EPPEventResponse that new connecting clients should receive. In this case the EPPGreeting.

Parameters:

aInputStream - The InputStream of the new connection.

aOutputStream - The OutputStream to send the response on.

aData - Any extra data that the connection handler may need.

setAssembler

public void setAssembler(EPPAssembler aAssembler)

Sets the Assembler. The format of the Input/Output streams determines the type of Assembler that should be used.

Parameters:

aAssembler - The type of Assembler to use.

processMessage

public void processMessage(java.io.InputStream aInputStream,
                           java.io.OutputStream aOutputStream,
                           java.lang.Object aData)
                    throws EPPEventException,
                           EPPAssemblerException

Creates an EPPMessage, sends the message to the appropriate EPPEventHandler, and then sends the response on the OutputStream.

Parameters:

aInputStream - The InputStream used to create the EPPMessage

aOutputStream - The OutputStream to send the EPPResponse on

aData - Any additional data that may be required by the EPPEventHandler

Throws:

EPPEventException - Exception related to the handling of an event

EPPAssemblerException - Exception related to the assembling/de-assembling of messages. EPPAssemberException.isFatal can be called to determine if the exception is a fatal exception for the client session.

registerHandler

public void registerHandler(EPPEventHandler aHandler)

Registers an EPPEvenHandler for notification of Events.

Parameters:

aHandler - The EPPEventhandler to register

registerConnectionHandler

Registers a EPPConnectionHandler for notification of connection events

Parameters:

aConnectionHandler - The connection handler to registier

send

public void send(EPPMessage aMessage,
                 java.io.OutputStream aOutputStream)
          throws EPPAssemblerException
