public class LogicBlocks<V extends LogicBlock>
extends LinkedList<V>
implements JSONFunctor

A collection of LogicBlock objects. A logic block is an if-then-else construct. Executing these will result in a collection of results. There are various sublcasses of this that do various things: XORLogicBlocks, ANDLogicBlocks and ORLogicBlocks.

Constructor Detail

LogicBlocks

public LogicBlocks(int connector)

LogicBlocks

public LogicBlocks()

A default constructor. You need to set the connector type before invoking execute() or this will fail.

Method Detail

setConnector

public void setConnector(int connector)

getResult

public Object getResult()

Specified by:

getResult in interface JMetaMetaFunctor

getFunctorMap

public FunctorMap getFunctorMap()

execute

public Object execute()

Specified by:

execute in interface JMetaMetaFunctor

doXORCase

protected boolean doXORCase(LogicBlock lb)

The logical connector is excluive or. This means that the processing ends as soon as the first block is true. else -- the else result will be added to the functor map, BUT execution will stop. Invoking the XOR connector means to stop processing in this case!!!

Parameters:

lb -

Returns:

updateFunctormap

protected void updateFunctormap(LogicBlock lb)

doORCase

protected boolean doORCase(LogicBlock lb)

This will execute every logic block and take the logical OR of all the results. Each consequent will be added

Parameters:

lb -

Returns:

doANDCase

protected boolean doANDCase(LogicBlock lb)

This will execute every logic block and take logicla AND of all the results. Processing continues for all of these. Note that only in the case of XOR is processing interrupted.

Parameters:

lb -

Returns:

clearState

public void clearState()

Clears each of the execution states of the logic blocks

isExecuted

public boolean isExecuted()

getConsequents

public List<jThen> getConsequents()

toJSON

public net.sf.json.JSONObject toJSON()

Specified by:

toJSON in interface JSONFunctor
