public static class HierarchicalConfiguration.Node
extends DefaultConfigurationNode
implements 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

HierarchicalConfiguration.Node

public HierarchicalConfiguration.Node()
Creates a new instance of Node.


HierarchicalConfiguration.Node

public HierarchicalConfiguration.Node(String name)
Creates a new instance of Node and sets the name.

Parameters:
name - the node's name

HierarchicalConfiguration.Node

public HierarchicalConfiguration.Node(String name,
                                      Object value)
Creates a new instance of Node and sets the name and the value.

Parameters:
name - the node's name
value - the value

HierarchicalConfiguration.Node

public HierarchicalConfiguration.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(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 pathes to the visited nodes are builded and passed to the visitor's visit() methods
