Method Detail

init

public void init()

This will handle the initial processing It will do any backlog of requests by looking for unprocessed tuples It will set up RegisterEvent to process all future events

call

public boolean call(java.lang.String eventName,
                    java.lang.String tsName,
                    int seqNum,
                    SuperTuple tuple,
                    boolean isException)

Implementation for the Callback interface.

Specified by:

call in interface Callback

Parameters:

eventName_ - the name of the event command that caused this call, that is the name of the client side command of the thread that registered this call, e.g., in the case of a read, this would be TupleSpace.READ, **not** TupleSpace.WRITE which is the corresponding command that caused the actaul event.

tsName_ - the name of the tuple space this command was executed on.

sequenceNumber_ - the sequenceNumber for this event/command

tuple_ - the returned tuple or a Tuple with an exception inside

isException_ - was the command processed normaly or was there an exception

Returns:

true if this is the last call this sequence # should be getting otherwise false

run

public void run()

The run() method will wait for pager Tuple to be queued The Tuple has the format: [ String name, String to-page-addr, String message ]

Specified by:

run in interface java.lang.Runnable

page

public void page(java.lang.String toaddr,
                 java.lang.String msg)

The page(toaddr,msg) method will send the msg to toaddr

main

public static void main(java.lang.String[] argv)

Startup the SendMail Process
