Class DefaultRuleEngine

java.lang.Object

com.highqsoft.xsd.AbstractImplementation

com.highqsoft.xsd.DefaultRuleEngine

All Implemented Interfaces:

ExecutableIF, ImplementationIF, RuleEngineIF

Direct Known Subclasses:

SimpleRuleEngine

public class DefaultRuleEngine
extends AbstractImplementation
implements RuleEngineIF

This is the default rule engine.
If the the rules are driven by the FROM the engine initializes the FROMrules first. Same thing for the TO driven case.

public DefaultRuleEngine()

Method Detail

init

public void init()
          throws InitializationFailedException

Initialize the program.

Specified by:

init in interface ImplementationIF

Specified by:

init in class AbstractImplementation

Throws:

InitializationFailedException - if the initialization fails.

attachJob

public void attachJob(Job job)
               throws InitializationFailedException

Attach the job descriptor to the engine. This is used to read the rules from job descriptor. This method is called after the initialization process of the implementation interface and before the execute method is called.

Specified by:

attachJob in interface RuleEngineIF

Parameters:

job - the job descriptor.

Throws:

InitializationFailedException

getDrivingSide

protected java.lang.String getDrivingSide()

execute

public void execute()
             throws ExecutableException

Start the engine (second step).

Specified by:

execute in interface ExecutableIF

Throws:

ExecutableException - if execution fails.

driveTo

protected void driveTo()
                throws ExecutableException,
                       TerminationException

Drive the rules from the TO side.

Throws:

ExecutableException

TerminationException

driveFrom

protected void driveFrom()
                  throws ExecutableException,
                         TerminationException

Drive the rules from the FROM side.

Throws:

ExecutableException

TerminationException

findRules

protected int[] findRules(RuleIF[] arr,
              java.lang.String id)

Find a set of rules having the same id.

Parameters:

arr - an array of rules.

id - the given id to be found.

Returns:

the index array into the given rule array.

handleTypedRule

public void handleTypedRule(TypedRuleIF rule)

Handle a typed rule.

terminate

public void terminate()
               throws TerminationException

Terminate the engine (third step).

Specified by:

terminate in interface ExecutableIF

Throws:

TerminationException - if termination fails.

execute

protected void execute(Implementationseq seq)
                throws ExecutableException

Execute a list of executables.

Parameters:

seq - The list of executables

Throws:

ExecutableException
