All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

RSM

public static class RSM.SendInterface

extends edu.umn.cs.crisys.RSM.Interface

implements java.lang.Runnable

RSML-e Send Interfaces. This provides an (asynchronous) send operation by running as a separate thread sending queued output messages over its channel. The state-machine implementation should call the send method to send messages over this output interface. Since the receives are synchronous, the sends or asynchronous, otherwise there is a possibility of deadlock.

Field Summary

protected boolean	isOpen flag to indicate state of this RMSL-e interface.
protected edu.umn.cs.crisys.nimbus.NimbusJavaWrapper	myChannel
edu.umn.cs.crisys.RSM.Message	myMessage Reference to my message object which stores the latest message on this interface.
java.lang.String	myName Descriptive name for this interface.

Constructor Summary

RSM.SendInterface(java.lang.String name, java.lang.String channelName, edu.umn.cs.crisys.RSM.Message msg)
Constructor.

Method Summary

void	close() Closes this interface by calling super.close().
void	open() Initializes interface for communication by calling super.open().
void	run() The main method called by the execution thread for this interface.
void	send() Method to be called by state-machine implementations to send messages over this interface.

Field Detail

myName

public final java.lang.String myName

Descriptive name for this interface.

myChannel

protected edu.umn.cs.crisys.nimbus.NimbusJavaWrapper myChannel

myMessage

public final edu.umn.cs.crisys.RSM.Message myMessage

Constructor Detail

RSM.SendInterface

public RSM.SendInterface(java.lang.String name,
                         java.lang.String channelName,
                         edu.umn.cs.crisys.RSM.Message msg)

Constructor. Calls the interface constructor with the passed parameters adding the appropriate channel type.

Method Detail

run

public void run()

The main method called by the execution thread for this interface. Waits for an output message to be queued and then sends it over its channel. Stops when the interface is closed.

Specified by:

run in interface java.lang.Runnable

open

public void open()

Initializes interface for communication by calling super.open(). Starts off its execution thread to send messages over the channel.

Overrides:

open in class edu.umn.cs.crisys.RSM.Interface

close

public void close()

Closes this interface by calling super.close(). Interrupts its execution thread so that it can verify the closed status and stop execution.

Overrides:

close in class edu.umn.cs.crisys.RSM.Interface

send

public void send()

Method to be called by state-machine implementations to send messages over this interface. The message, in reality, gets queued and is later sent by this interface's execution thread.
