Class EditPointMouseTransformFactory.SelectedPointsHandler

java.lang.Object
  jpicedt.graphic.toolkit.EditPointMouseTransformFactory.SelectedPointsHandler

Enclosing class:

EditPointMouseTransformFactory

protected class EditPointMouseTransformFactory.SelectedPointsHandler
extends Object

Helper class for SelectPointsInAreaTransform. This is a typesafe container for ONE Element and the indices of its selected-points

Indices are ALWAYS sorted in descending order : this helps e.g. RemovePointTransform removing curve's points starting from the end (this is made necessary so as to preserve the meaning of yet-to-be-removed points indices ; removing points starting from index "0" would surely lead to odd behaviour since ensuing indices would be shifted to the "left").

Constructor Summary

EditPointMouseTransformFactory.SelectedPointsHandler()

Method Summary

void	clear() clears the state of this handler by removing the reference to the current Element and its selected points
Element	getElement() returns the current target Element
int	getSelectionSize() return the number of selected points for the current element
Iterator	indexIterator() return an Iterator over the set of selected-points indices (wrapped in Integer's)
boolean	isSelected(HitInfo.Point hip) Return true if at least one point in the given HitInfo.Point is selected
boolean	isSelected(int idx) Returns true if the point with the given index is selected.
void	selectPoint(int idx) adds the given point index to the selection
void	setElement(Element e) sets the current Element and clears the list of selected-points
String	toString()
void	unSelectPoint(int idx) removes the given point index to the selection
