Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`constrain(java.awt.geom.Point2D point)`	Ask the point constraint to constrain this point.
`boolean`	`snapped()`	Ask the point constraint call to constrain() cause a "snap." A snap means that the output value of the point changed from one region to another.

- Method Detail
  - constrain
```
void constrain(java.awt.geom.Point2D point)
```
    Ask the point constraint to constrain this point. The constraint should directly modify the passed point.
  - snapped
```
boolean snapped()
```
    Ask the point constraint call to constrain() cause a "snap." A snap means that the output value of the point changed from one region to another. If a snap did occur, the caller will probably fire a ConstraintEvent.
