GC.GCB

Reuse objects; 'getClipBounds()' should not be called too often

Description

This rule flags code that calls `getClipBounds()' too often.

The `getClipBounds()' method always returns a new rectangle. Allocating more memory every time this method is called overworks the garbage collector.

Note: Violations are only reported for methods with more than one `getClipBounds()'.

Example

 package GC;
 import java.awt.Graphics;
 
 public class GCB {
     public void paint(Graphics g) {
         int firstColLine = g.getClipBounds().x;
         int lastColLine = g.getClipBounds().x + g.getClip-
Bounds().width;
     }
 }

Repair

 package GC;
 
 import java.awt.Graphics;
 import java.awt.Rectangle;
 
 public class GCB {
     public void paint(Graphics g) {
         Rectangle rec = g.getClipBounds();// instantiate a object,
rec
         int firstColLine = rec.x; // reuse "rec"
         int lastColLine = rec.x + rec.width;   // reuse "rec"
     }
 }
