GraphLink.LinkableFrom

All Known Implementing Classes:: LineElement.LinePoint

Enclosing class:: GraphLink

public static interface GraphLink.LinkableFrom

Classes which want to refer *to* a GraphLink.LinkableTo PathwayElement must implement this interface. At this time that only goes for LineElement.LinePoint.

Method Summary

Modifier and Type	Method	Description
`GraphLink.LinkableTo`	`getElementRef()`	Returns the `GraphLink.LinkableTo` pathway element this `GraphLink.LinkableFrom` elementRef refers to.
`double`	`getRelX()`	Returns the relative x coordinate.
`double`	`getRelY()`	Returns the relative y coordinate.
`void`	`linkTo(GraphLink.LinkableTo elementRef, double relX, double relY)`	Links this linkableFrom (e.g.
`void`	`refeeChanged()`	Called whenever the object being referred to changes coordinates.
`void`	`unlink()`	Unlinks this linkableFrom (e.g.

Method Details
- getElementRef
  
  GraphLink.LinkableTo getElementRef()
  
  Returns the GraphLink.LinkableTo pathway element this GraphLink.LinkableFrom elementRef refers to.
  
  Returns:
  
  the LinkableTo elementRef refers to.
- getRelX
  
  double getRelX()
  
  Returns the relative x coordinate. When the given point is linked to a pathway element, relX and relY are the relative coordinates on the element, where 0,0 is at the center of the object and 1,1 at the bottom right corner of the object.
  
  Returns:
  
  the relative x.
- getRelY
  
  double getRelY()
  
  Returns the relative y coordinate. When the given point is linked to a pathway element, relX and relY are the relative coordinates on the element, where 0,0 is at the center of the object and 1,1 at the bottom right corner of the object.
  
  Returns:
  
  the relative y.
- linkTo
  
  void linkTo(GraphLink.LinkableTo elementRef, double relX, double relY)
  
  Links this linkableFrom (e.g. linePoint) to the given linkableTo.
  
  Parameters:
  
  elementRef - the linkableTo pathway element.
  
  relX - the relative x coordinates.
  
  relY - the relative y coordinates.
- unlink
  
  void unlink()
  
  Unlinks this linkableFrom (e.g. linePoint) from linkableTo pathway element.
- refeeChanged
  
  void refeeChanged()
  
  Called whenever the object being referred to changes coordinates.
