Interface NodePort.UnionRectCalculator

All Known Implementing Classes:

ShapePortConfiguration

Enclosing class:

NodePort

public static interface NodePort.UnionRectCalculator

This interface is used by NodePort to delegate the work of the NodePort.calcUnionRect(java.awt.geom.Rectangle2D) method to.

Classes implementing this interface should query the given context port instance for the necessary information each time the methods are called since instances of this interface will be shared for multiple NodePort instances.

Method Summary

void	calcUnionRect(NodePort port, java.awt.geom.Rectangle2D rectangle) Calculates the rectangular union of the specified rectangle and the specified port's bounds.
