MAP_DATA_CHANGED

public static final EventType MAP_DATA_CHANGED

Event for a change in data that entails a change in visualization.

Constructor Details

MapData

public MapData(EditorMap map,
 XsdTreeNode node,
 OtsEditor editor)

Constructor.

Parameters:

map - map.

node - tree node.

editor - editor.

Method Details

getNode

public XsdTreeNode getNode()

Returns the tree node.

Returns:

tree node.

getEval

public Eval getEval()

Returns the evaluator for expressions.

Returns:

evaluator for expressions.

destroy

public void destroy()

Destroy this data object, e.g. remove self as listener. Override and call super if subclasses remove their own listeners. Using weak references for listeners is another option to deal with obsolete listening.

isValid

public boolean isValid()

Returns whether this data is valid.

Returns:

whether this data is valid

getMap

protected EditorMap getMap()

Returns the map.

Returns:

map.

setValue

protected <T> void setValue(Consumer<T> setter,
 ExpressionAdapter<T,?> adapter,
 XsdTreeNode treeNode,
 String attribute)

Generic method to set a value based on a changed attribute. If the new value is null, the setter is invoked to set a null value. If the value is an invalid expression, or the value cannot be unmarshalled by the adapter, no change is made.

Type Parameters:

T - type of the value to set.

Parameters:

setter - setter that receives a successfully derived value.

adapter - adapter.

treeNode - node that has the attribute, will often be getNode().

attribute - name of the attribute.
