谁能告诉我tree组件中节点顺序是怎样处理的？
我按照网上的例子，发现节点顺序并不是以insert顺序或节点类的hascode为准。 节点类： public class MyNode extends TreeNode { //- private static final long serialVersionUID = 1L2; protected String value; private int post; MyNode(String val，int post) { super(null); value=val; this.post=post; } public String toString() { return value; } public int hashCode() { //return value.hashCode(); return this.post; } public boolean equals(Object objTarget) { if(objTarget==this) return true; if(!(objTarget instanceof MyNode)) return false; MyNode objTargetNode = (MyNode)objTarget; return value.equals(objTargetNode.value); } } |
