Constructor Detail

RemoteReceiverStreamClient

public RemoteReceiverStreamClient(java.lang.String id,
                                  java.net.Socket socket)

Constructs a new client.

Parameters:

id - identifier string for the client

socket - socket to which logging events will be written

RemoteReceiverStreamClient

RemoteReceiverStreamClient(java.lang.String id,
                           java.io.OutputStream outputStream)

Constructs a new client.

This constructor exists primarily to support unit tests where it is inconvenient to have to create a socket for the test.

Parameters:

id - identifier string for the client

outputStream - output stream to which logging Events will be written

Method Detail

setQueue

public void setQueue(java.util.concurrent.BlockingQueue<java.io.Serializable> queue)

Sets the client's event queue.

This method must be invoked before the Runnable.run() method is invoked.

Specified by:

setQueue in interface RemoteReceiverClient

Parameters:

queue - the queue to set

offer

public boolean offer(java.io.Serializable event)

Offers an event to the client.

Specified by:

offer in interface RemoteReceiverClient

Parameters:

event - the subject event

Returns:

true if the client's queue accepted the event, false if the client's queue is full

close

public void close()

Closes any resources that are held by the client.

Note that (as described in Doug Lea's discussion about interrupting I/O operations in "Concurrent Programming in Java" (Addison-Wesley Professional, 2nd edition, 1999) this method is used to interrupt any blocked I/O operation in the client when the server is shutting down. The client implementation must anticipate this potential, and gracefully exit when the blocked I/O operation throws the relevant IOException subclass.

Note also, that unlike Closeable.close() this method is not permitted to propagate any IOException that occurs when closing the underlying resource(s).

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface Client

Specified by:

close in interface java.io.Closeable

run

public void run()

Specified by:

run in interface java.lang.Runnable

createObjectOutputStream

private java.io.ObjectOutputStream createObjectOutputStream()
                                                     throws java.io.IOException

Throws:

java.io.IOException
