Constructor Detail

NamespaceImpl

public NamespaceImpl(ElementImpl element,
                     int nsCode,
                     int index)
Construct a Namespace node

Parameters:
element - The element owning the namespace node
nsCode - The namespace code
index - Integer identifying this namespace node among the nodes for its parent
Method Detail

getNameCode

public int getNameCode()
Get the namecode for this name. Not the same as the namespace code!

Specified by:
getNameCode in interface NodeInfo
Overrides:
getNameCode in class NodeImpl

getNamespaceCode

public int getNamespaceCode()
Get the namespace code for this prefix/uri pair. Not the same as the name code!


isSameNode

public boolean isSameNode(NodeInfo other)
Determine whether this is the same node as another node

Specified by:
isSameNode in interface NodeInfo
Overrides:
isSameNode in class NodeImpl
Returns:
true if this Node object and the supplied Node object represent the same node in the tree.

getLocalName

public String getLocalName()
Get the prefix of the namespace that this node relates to

Specified by:
getLocalName in interface Node
Overrides:
getLocalName in class NodeImpl
Returns:
The local name of this node. For a node with no name, return an empty string.

setNamespaceCode

public void setNamespaceCode(int nsCode)
Change the uri of the namespace that this node relates to (used to implement xsl:namespace-alias)


getNodeType

public final short getNodeType()
Return the type of node.

Returns:
NodeInfo.NAMESPACE

getStringValue

public String getStringValue()
Return the string value of the node.

Returns:
the namespace uri

getNodeName

public String getNodeName()
Get the name of this node, following the DOM rules (which aren't actually defined for Namespace nodes...)

Specified by:
getNodeName in interface Node
Overrides:
getNodeName in class AbstractNode
Returns:
the namespace prefix

getNextSibling

public Node getNextSibling()
Get next sibling - not defined for namespace nodes

Specified by:
getNextSibling in interface Node
Overrides:
getNextSibling in class NodeImpl
Returns:
The next sibling node of the required type. Returns null if the current node is the last child of its parent.

getPreviousSibling

public Node getPreviousSibling()
Get previous sibling - not defined for namespace nodes

Specified by:
getPreviousSibling in interface Node
Overrides:
getPreviousSibling in class NodeImpl
Returns:
The previous sibling node. Returns null if the current node is the first child of its parent.

getPreviousInDocument

public NodeImpl getPreviousInDocument()
Get the previous node in document order (skipping namespace nodes)

Overrides:
getPreviousInDocument in class NodeImpl
Returns:
the previous node in the document, or null if there is no such node

getNextInDocument

public NodeImpl getNextInDocument(NodeImpl anchor)
Get the next node in document order (skipping namespace nodes)

Overrides:
getNextInDocument in class NodeImpl
Returns:
the next node in the document, or null if there is no such node

generateId

public String generateId()
Get sequential key. Returns key of owning element with the namespace prefix as a suffix

Specified by:
generateId in interface NodeInfo
Overrides:
generateId in class NodeImpl
Returns:
a string.

copy

public void copy(Outputter out)
          throws TransformerException
Copy this node to a given outputter

Throws:
TransformerException

getSequenceNumber

protected long getSequenceNumber()
Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and roots) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position.

Overrides:
getSequenceNumber in class NodeImpl
