All Implemented Interfaces:

java.io.Serializable, ConfigurationNode

Direct Known Subclasses:

XMLPropertyListConfiguration.PListNode

Enclosing class:

HierarchicalConfiguration

public static class HierarchicalConfiguration.Node
extends DefaultConfigurationNode
implements java.io.Serializable

A data class for storing (hierarchical) property information. A property can have a value and an arbitrary number of child properties. From version 1.3 on this class is only a thin wrapper over the DefaultconfigurationNode class that exists mainly for the purpose of backwards compatibility.

Constructor Detail

Node

public Node()

Creates a new instance of Node.

Node

public Node(java.lang.String name)

Creates a new instance of Node and sets the name.

Parameters:

name - the node's name

Node

public Node(java.lang.String name,
            java.lang.Object value)

Creates a new instance of Node and sets the name and the value.

Parameters:

name - the node's name

value - the value

Node

public Node(ConfigurationNode src)

Creates a new instance of Node based on the given source node. All properties of the source node, including its children and attributes, will be copied.

Parameters:

src - the node to be copied

Method Detail

getParent

public HierarchicalConfiguration.Node getParent()

Returns the parent of this node.

Returns:

this node's parent (can be null)

setParent

public void setParent(HierarchicalConfiguration.Node node)

Sets the parent of this node.

Parameters:

node - the parent node

addChild

public void addChild(HierarchicalConfiguration.Node node)

Adds the given node to the children of this node.

Parameters:

node - the child to be added

hasChildren

public boolean hasChildren()

Returns a flag whether this node has child elements.

Returns:

true if there is a child node, false otherwise

remove

public boolean remove(HierarchicalConfiguration.Node child)

Removes the specified child from this node.

Parameters:

child - the child node to be removed

Returns:

a flag if the child could be found

remove

public boolean remove(java.lang.String name)

Removes all children with the given name.

Parameters:

name - the name of the children to be removed

Returns:

a flag if children with this name existed

visit

public void visit(HierarchicalConfiguration.NodeVisitor visitor,
                  ConfigurationKey key)

A generic method for traversing this node and all of its children. This method sends the passed in visitor to this node and all of its children.

Parameters:

visitor - the visitor

key - here a configuration key with the name of the root node of the iteration can be passed; if this key is not null , the full paths to the visited nodes are builded and passed to the visitor's visit() methods
