Constructor Detail
-
NamespaceImpl
public NamespaceImpl(ElementImpl element, int nsCode, int index)
Construct a Namespace node- Parameters:
element
- The element owning the namespace nodensCode
- The namespace codeindex
- 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 interfaceNodeInfo
- Overrides:
getNameCode
in classNodeImpl
- 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 interfaceNodeInfo
- Overrides:
isSameNodeInfo
in classNodeImpl
- 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 interfaceorg.w3c.dom.Node
- Specified by:
getLocalName
in interfaceNodeInfo
- Overrides:
getLocalName
in classNodeImpl
- 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 interfaceorg.w3c.dom.Node
- Overrides:
getNodeName
in classAbstractNode
- Returns:
- the namespace prefix
-
getNextSibling
public org.w3c.dom.Node getNextSibling()
Get next sibling - not defined for namespace nodes- Specified by:
getNextSibling
in interfaceorg.w3c.dom.Node
- Overrides:
getNextSibling
in classNodeImpl
- 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 interfaceorg.w3c.dom.Node
- Overrides:
getPreviousSibling
in classNodeImpl
- 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 classNodeImpl
- 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 classNodeImpl
- 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 interfaceNodeInfo
- Overrides:
generateId
in classNodeImpl
- 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 classNodeImpl
