Node (Hadoop 1.2.2-SNAPSHOT API)

java.lang.Object
- org.apache.hadoop.tools.rumen.Node

所有已实现的接口:

Comparable<Node>

直接已知子类:

MachineNode, RackNode
```
public class Node
extends Object
implements Comparable<Node>
```
Node represents a node in the cluster topology. A node can be a MachineNode, or a RackNode, etc.

public Node(String name,
    int level)
```
    参数:
    name - A unique name to identify a node in the cluster.
    level - The level of the node in the cluster
- 方法详细资料
  - getName
```
public String getName()
```
    Get the name of the node.
    
    返回:
    The name of the node.
  - getLevel
```
public int getLevel()
```
    Get the level of the node.
    
    返回:
    The level of the node.
  - addChild
```
public boolean addChild(Node child)
```
    Add a child node to this node.
    
    参数:
    child - The child node to be added. The child node should currently not be belong to another cluster topology.
    
    返回:
    Boolean indicating whether the node is successfully added.
  - hasChildren
```
public boolean hasChildren()
```
    Does this node have any children?
    
    返回:
    Boolean indicate whether this node has any children.
  - getChildren
```
public Set<Node> getChildren()
```
    Get the children of this node.
    
    返回:
    The children of this node. If no child, an empty set will be returned. The returned set is read-only.
  - getParent
```
public Node getParent()
```
    Get the parent node.
    
    返回:
    the parent node. If root node, return null.
  - hashCode
```
public int hashCode()
```
    覆盖:
    
    hashCode 在类中 Object
  - equals
```
public boolean equals(Object obj)
```
    覆盖:
    
    equals 在类中 Object
  - toString
```
public String toString()
```
    覆盖:
    
    toString 在类中 Object
  - compareTo
```
public int compareTo(Node o)
```
    指定者:
    
    compareTo 在接口中 Comparable<Node>
