Method Detail

init

public void init()
          throws AbleException

Description copied from class: AbleObject

Initialize and configure the bean. The bean's state changes to AbleState.Initiated or AbleState.Waiting. If either the AbleEventProcessing or TimerEventProcessing flags are enabled, this method calls AbleObject.startEnabledEventProcessing() to start a new thread for asynchronous or timer event processing.

An AbleProperty.ProcessingState PropertyChangeEvent is fired.

Beans overriding this method should call super.init() after any customization and before returning so that the thread is started if needed and the PropertyChangeEvent is fired.

An application using asynchronous or timer event processing should sleep until the event queue is functional by imbedding logic like this:

    anAbleObject.init();
    while (!AbleState.isReady(anAbleObject.getState())) {
        try {
            Thread.sleep(100l);
        } catch (InterruptedException e1) {
        }
    }
 

Specified by:

init in interface AbleBean

Overrides:

init in class AbleObject

Throws:

AbleException - If an error occurs.

See Also:

AbleObject.startEnabledEventProcessing()

reset

public void reset()
           throws AbleException

Description copied from class: AbleObject

Reset this bean to its "initialized" state.

This base method has no default implementation. It only provides tracing.

Specified by:

reset in interface AbleBean

Overrides:

reset in class AbleObject

Throws:

AbleException - If an error occurs.

See Also:

AbleBean.reset()

resetStatistics

public void resetStatistics()
                     throws AbleException

Throws:

AbleException

initFromImport

protected void initFromImport()
                       throws AbleException

Throws:

AbleException

copyInfo

protected void copyInfo()
                 throws AbleException

Throws:

AbleException

copyTrainData

protected void copyTrainData()
                      throws AbleException

Throws:

AbleException

copyTestData

protected void copyTestData()
                     throws AbleException

Throws:

AbleException

process

public void process()
             throws AbleException

Description copied from class: AbleObject

Performs the main, synchronous, standard processing function performed by this bean.

This base method implementation provides tracing only.

Specified by:

process in interface AbleBean

Overrides:

process in class AbleObject

Throws:

AbleException

See Also:

AbleObject.inputBuffer, AbleObject.outputBuffer, AbleBean.process()

processTimerEvent

public void processTimerEvent()
                       throws AbleException

Description copied from class: AbleObject

Process a timer expiration event synchronously; that is, on the same thread as the caller.

This method is called by the AbleEventQueue whenever the following conditions are all true:

• The queue's asynchronous thread of control is running.
• Timer event processing is enabled.
• The amount of time specified in AbleObject.setSleepTime(long) has expired.

This base method has no default implementation. It provides only tracing.

Specified by:

processTimerEvent in interface AbleEventQueueProcessor

Overrides:

processTimerEvent in class AbleObject

Throws:

AbleException - If an error occurs.

handleAbleEvent

public void handleAbleEvent(AbleEvent theEvent)

Description copied from interface: AbleEventListener

Handles an Able event. Most implementations will check to see if the event should be processed synchronously (on the same thread as the caller) or asynchronously (on a separate thread).

Specified by:

handleAbleEvent in interface AbleEventListener

Overrides:

handleAbleEvent in class AbleObject

setNetMode

public void setNetMode(int newValue)
                throws AbleException

Set the value for some String property in BeanWrapper, and fire a propertyChange event to notify any propertyChange listeners.

Throws:

AbleException

getNetMode

public int getNetMode()

Get the value for some String property from the BeanWrapper

getPercentCorrect

public double getPercentCorrect()

Get the value for some String property from the BeanWrapper

getTotalPredClass

getCorrectPredClass

public int getCorrectPredClass()

getIncorrectPredClass

public int getIncorrectPredClass()

getValsTrainClass

public short[] getValsTrainClass()

getValsTestClass

getPredictClass

public java.lang.String getPredictClass()

getPredictClassIndex

public int getPredictClassIndex()

getCurrentExample

public int getCurrentExample()

setDiscretizationInterval

public void setDiscretizationInterval(int theCount)

getDiscretizationInterval

setDecisionTreeBuilt

public void setDecisionTreeBuilt(boolean theValue)
                          throws AbleException

Throws:

AbleException

isDecisionTreeBuilt

public boolean isDecisionTreeBuilt()

getDecisionTreeBuilt

public boolean getDecisionTreeBuilt()

getDecisionTreeAsString

public java.lang.String getDecisionTreeAsString()

Return null if tree has not been built, and a formatted text representation if one has been built.
