All Implemented Interfaces:

EventListener, TreeModelListener, State

public class SwingTreeModelFillState
extends AbstractSwingState
implements State, TreeModelListener

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

Constructor Detail

SwingTreeModelFillState

public SwingTreeModelFillState(JTree pTree)

Creates a new state, using the model of the handed tree as its state source. If the model contains at least one element (not counting the root element as element), then the state is true.

Parameters:

pTree - tree we take the model from, must not be null

SwingTreeModelFillState

public SwingTreeModelFillState(JTree pTree,
                       boolean pCountRootAsContent)

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

Parameters:

pTree - tree we take the model from, must not be null

pCountRootAsContent - indicates whether the root-node is counted as content or not

SwingTreeModelFillState

public SwingTreeModelFillState(TreeModel pModel,
                       boolean pCountRootAsContent,
                       int pThreshold)

Creates a new state, using the handed model as its state source. If the model contains any data, then the state is true.

Parameters:

pModel - the model we monitor, must not be null

pCountRootAsContent - indicates whether the root-node is counted as content or not

pThreshold - threshold of items in the tree

Method Detail

setCompareContent

public void setCompareContent(int pThreshold)

Sets the threshold we compare again.

Parameters:

pThreshold - threshold of items in the tree

treeNodesChanged

public void treeNodesChanged(TreeModelEvent pEvent)

Callback method for our tree model.

Specified by:

treeNodesChanged in interface TreeModelListener

Parameters:

pEvent - not used

treeNodesInserted

public void treeNodesInserted(TreeModelEvent pEvent)

Callback method for our tree model.

Specified by:

treeNodesInserted in interface TreeModelListener

Parameters:

pEvent - not used

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent pEvent)

Callback method for our tree model.

Specified by:

treeNodesRemoved in interface TreeModelListener

Parameters:

pEvent - not used

treeStructureChanged

public void treeStructureChanged(TreeModelEvent pEvent)

Callback method for our tree model.

Specified by:

treeStructureChanged in interface TreeModelListener

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
