Method Summary
public NodeIterator	attributeIterator(QName name) Returns an iterator for the attributes that match the given name.
public NodeIterator	childIterator(NodeTest test, boolean reverse, NodePointer startWith) Returns an iterator for the children of this pointer that match the given test object.
public int	compareChildNodePointers(NodePointer pointer1, NodePointer pointer2) Compares two child node pointers.
public Object	getBaseValue() Returns this node's base value.
public Object	getImmediateNode() Returns the immediate node.
public int	getLength() Returns this node's length.
public QName	getName() Returns this node's name.
public Object	getValue() Returns the value of this node.
public boolean	isAttribute() Checks whether this node pointer refers to an attribute node.
public boolean	isCollection() Returns a flag if this node is a collection.
public boolean	isLeaf() Returns a flag whether this node is a leaf.
public void	setValue(Object value) Sets the value of this node.
public boolean	testNode(NodeTest test) Tests if this node matches the given test.

Constructor Detail

ConfigurationNodePointer
public ConfigurationNodePointer(ConfigurationNode node, Locale locale)(Code)
	Creates a new instance of `ConfigurationNodePointer`. Parameters: node - the node Parameters: locale - the locale

ConfigurationNodePointer
public ConfigurationNodePointer(NodePointer parent, ConfigurationNode node)(Code)
	Creates a new instance of `ConfigurationNodePointer` and initializes it with its parent pointer. Parameters: parent - the parent pointer Parameters: node - the associated node

Method Detail

attributeIterator
public NodeIterator attributeIterator(QName name)(Code)
	Returns an iterator for the attributes that match the given name. Parameters: name - the attribute name the iterator for the attributes

childIterator
public NodeIterator childIterator(NodeTest test, boolean reverse, NodePointer startWith)(Code)
	Returns an iterator for the children of this pointer that match the given test object. Parameters: test - the test object Parameters: reverse - the reverse flag Parameters: startWith - the start value of the iteration

compareChildNodePointers
public int compareChildNodePointers(NodePointer pointer1, NodePointer pointer2)(Code)
	Compares two child node pointers. Parameters: pointer1 - one pointer Parameters: pointer2 - another pointer a flag, which pointer should be sorted first

getBaseValue
public Object getBaseValue()(Code)
	Returns this node's base value. This is the associated configuration node. the base value

getImmediateNode
public Object getImmediateNode()(Code)
	Returns the immediate node. This is the associated configuration node. the immediate node

getLength
public int getLength()(Code)
	Returns this node's length. This is always 1. the node's length

getName
public QName getName()(Code)
	Returns this node's name. the name

getValue
public Object getValue()(Code)
	Returns the value of this node. the represented node's value

isAttribute
public boolean isAttribute()(Code)
	Checks whether this node pointer refers to an attribute node. This method checks the attribute flag of the associated configuration node. the attribute flag

isCollection
public boolean isCollection()(Code)
	Returns a flag if this node is a collection. This is not the case. the collection flag

isLeaf
public boolean isLeaf()(Code)
	Returns a flag whether this node is a leaf. This is the case if there are no child nodes. a flag if this node is a leaf

setValue
public void setValue(Object value)(Code)
	Sets the value of this node. Parameters: value - the new value

testNode
public boolean testNode(NodeTest test)(Code)
	Tests if this node matches the given test. Configuration nodes are text nodes, too because they can contain a value. Parameters: test - the test object a flag if this node corresponds to the test
