All Implemented Interfaces:

EventListener, ListDataListener, State

public class SwingListModelFillState
extends AbstractSwingState
implements State, ListDataListener

The SwingListModelFillState class models a State with the ListModel of a Swing JList as the state source. The value of the state is determined by examining the ListModel's content. If the ListModel's content contains at least a provided number of elements (default: one element), the state is true.

Constructor Detail

SwingListModelFillState

public SwingListModelFillState(JList pList)

Creates a new state, using the model of the handed list as its state source. If the model contains at least one element, then the state is true.

Parameters:

pList - list we take the model from, must not be null

SwingListModelFillState

public SwingListModelFillState(JList pList,
                       int pThreshold)

Creates a new state, using the model of the handed list as its state source. If the model contains at least pThreshold elements, then the state is true.

Parameters:

pList - list we take the model from, must not be null

pThreshold - threshold of items in the list

SwingListModelFillState

public SwingListModelFillState(ListModel pModel,
                       int pThreshold)

Creates a new state, using the handed model as its state source. If the model contains at least pThreshold elements, then the state is true.

Parameters:

pThreshold - threshold of items in the list

pModel - the model we monitor, must not be null

Method Detail

setCompareContent

public void setCompareContent(int pThreshold)

Sets the threshold we compare again.

Parameters:

pThreshold - threshold of items in the list

contentsChanged

public void contentsChanged(ListDataEvent pEvent)

Callback method for our list model.

Specified by:

contentsChanged in interface ListDataListener

Parameters:

pEvent - not used

intervalAdded

public void intervalAdded(ListDataEvent pEvent)

Callback method for our list model.

Specified by:

intervalAdded in interface ListDataListener

Parameters:

pEvent - not used

intervalRemoved

public void intervalRemoved(ListDataEvent pEvent)

Callback method for our list model.

Specified by:

intervalRemoved in interface ListDataListener

Parameters:

pEvent - not used

getInternalState

protected boolean getInternalState()

Check if our model contains at least our threshold number of items.

Specified by:

getInternalState in class AbstractSwingState

Returns:

the state, true if the model contains enough items

setReason

protected void setReason()

Set the source of the state as the reason for a change.

Specified by:

setReason in class AbstractSwingState
