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

See Also:

allocate, getFingerprint

getNamespaceCode

public int getNamespaceCode()

Get the namespace code for this prefix/uri pair. Not the same as the name code!

isSameNodeInfo

public boolean isSameNodeInfo(NodeInfo other)

Determine whether this is the same node as another node

Specified by:

isSameNodeInfo in interface NodeInfo

Overrides:

isSameNodeInfo in class NodeImpl

Returns:

true if this Node object and the supplied Node object represent the same node in the tree.

getLocalName

public java.lang.String getLocalName()

Get the prefix of the namespace that this node relates to

Specified by:

getLocalName in interface org.w3c.dom.Node

Specified by:

getLocalName in interface NodeInfo

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 java.lang.String getStringValue()

Return the string value of the node.

Returns:

the namespace uri

getNodeName

public java.lang.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 org.w3c.dom.Node

Overrides:

getNodeName in class AbstractNode

Returns:

the namespace prefix

getNextSibling

public org.w3c.dom.Node getNextSibling()

Get next sibling - not defined for namespace nodes

Specified by:

getNextSibling in interface org.w3c.dom.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 org.w3c.dom.Node getPreviousSibling()

Get previous sibling - not defined for namespace nodes

Specified by:

getPreviousSibling in interface org.w3c.dom.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

Parameters:

anchor - : the scan stops when it reaches a node that is not a descendant of the specified anchor node

Returns:

the next node in the document, or null if there is no such node

generateId

public java.lang.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 javax.xml.transform.TransformerException

Copy this node to a given outputter

Throws:

javax.xml.transform.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
