Class XMLSequencer.Conditioner

java.lang.Object

java.lang.Thread

stella.xml.XMLSequencer.Conditioner

All Implemented Interfaces:

Runnable, AlarmHandler

Enclosing class:

XMLSequencer

private class XMLSequencer.Conditioner
extends Thread
implements AlarmHandler

The helper class that deals with incoming reply messages. First, the sequencer is called to convert the incoming reply to a valid variable name. Then, the conditioner roams through its list of variables and

• Sets variable with identical names to true.
• If a delay is encountered matching the variable under question, an Alarm thread is started with the entire variable's name as an argument, i.e. with the attached delay tag.

This method synchronizes on the variable map. It starts itself after construction.

Constructor Detail

Conditioner

private Conditioner(ReplyEvent rep)

Constructs and starts a new conditioner processing the argument reply event.

Method Detail

setOff

public void setOff(String varname)

This method is called if a delayed condition is met. I.e. booleans like DONE_MOVE+1000 are treated here. Whenever the DONE_MOVE reply is registered in the XMLSequencer.forward(stella.ReplyEvent) receiving end an Alarm is spawned with the specified delay time (ms). If the alarm ran out the alarm threads name is used to set the matching boolean variable to true.

Specified by:

setOff in interface AlarmHandler

Parameters:

The - name of the alarm thread equal the variable name

run

public void run()

The run method of the conditioner. It synchronizes on the variable map. Entries in this map matching the variable name constructed from the original reply are treated in the following way:

• Sets variable with identical names to true.
• If a delay is encountered matching the variable under question, an Alarm thread is started with the entire variable's name as an argument, i.e. with the attached delay tag.

Specified by:

run in interface Runnable

Overrides:

run in class Thread
