RichFaces TreeNode - 无法转换为 javax.swing.tree.TreeNode
RichFaces TreeNode - cannot be cast to javax.swing.tree.TreeNode
我正在尝试使用 RichFaces 树实现。我已经 subclassed TreeNodeImpl class - 下面是我的装饰器 superclass。我收到上述错误。当然，我没有实施 javax.swing.tree.TreeNode - 我正在实施 org.richfaces.model.TreeNode
package com.base.view.tree;
import org.richfaces.model.TreeNode;
import org.richfaces.model.TreeNodeImpl;
import com.iLearn.model.base.Typed;
public abstract class TreeNodeDecorator<T extends Typed> extends TreeNodeImpl implements TreeNode {
public TreeNodeDecorator(T theData) {
super();
setData(theData);
}
private T data;
public abstract String getDisplayString();
public abstract boolean isLeaf();
public T getData() {
return data;
}
public void setData(T theData) {
data = theData;
}
public String getType() {
return getData().getType();
}
}
