Get the prefix part of the name of this node. This is the name before the ":" if any.

Specified by:

getPrefix in interface Node

Overrides:

getPrefix in class TinyNodeImpl

Returns:

the prefix part of the name. Always null.

getDisplayName

public java.lang.String getDisplayName()

Get the display name of this node. For namespaces this is the namespace prefix.

Specified by:

getDisplayName in interface NodeInfo

Overrides:

getDisplayName in class TinyNodeImpl

Returns:

The display name of this node. For a node with no name, return an empty string.

getLocalName

public java.lang.String getLocalName()

Get the local name of this node. For namespaces this is the namespace prefix.

Specified by:

getLocalName in interface Node

Overrides:

getLocalName in class TinyNodeImpl

Returns:

The local name of this node.

getURI

public java.lang.String getURI()

Get the URI part of the name of this node.

Specified by:

getURI in interface NodeInfo

Overrides:

getURI in class TinyNodeImpl

Returns:

The URI of the namespace of this node. Always null.

getParent

public NodeInfo getParent()

Get the parent element of this namespace node

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

isSameNode

public final boolean isSameNode(NodeInfo other)

Determine whether this is the same node as another node

Specified by:

isSameNode in interface NodeInfo

Overrides:

isSameNode in class TinyNodeImpl

Returns:

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

getNodeType

public final short getNodeType()

Return the type of node.

Returns:

NodeInfo.NAMESPACE

getStringValue

public final java.lang.String getStringValue()

Return the string value of the node.

Returns:

the namespace uri

generateId

public java.lang.String generateId()

Get unique identifier. Returns key of owning element with the namespace prefix as a suffix

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Returns:

a string.

copy

public void copy(Outputter out)
          throws TransformerException

Copy this node to a given outputter

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 TinyNodeImpl

setSystemId

public void setSystemId(java.lang.String uri)

Set the system id of this node.
This method is present to ensure that the class implements the javax.xml.transform.Source interface, so a node can be used as the source of a transformation.

setParentNode

protected void setParentNode(TinyNodeImpl parent)

Set the parent of this node. Providing this information is useful, if it is known, because otherwise getParent() has to search backwards through the document.

getSystemId

public java.lang.String getSystemId()

Get the system ID for the entity containing the node.

Specified by:

getSystemId in interface NodeInfo

Specified by:

getSystemId in class AbstractNode

Returns:

the System Identifier of the entity in the source document containing the node, or null if not known. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot.

getBaseURI

public java.lang.String getBaseURI()

Get the base URI for the node. Default implementation for child nodes gets the base URI of the parent node.

Specified by:

getBaseURI in interface NodeInfo

Specified by:

getBaseURI in class AbstractNode

getOriginatingNode

public Node getOriginatingNode()

Get the node corresponding to this javax.xml.transform.dom.DOMLocator

Specified by:

getOriginatingNode in interface DOMLocator

Overrides:

getOriginatingNode in class AbstractNode

setLineNumber

public void setLineNumber(int line)

Set the line number of the node within its source document entity

getLineNumber

public int getLineNumber()

Get the line number of the node within its source document entity

Specified by:

getLineNumber in interface NodeInfo

Overrides:

getLineNumber in class AbstractNode

Returns:

the line number of the node in its original source document; or -1 if not available

compareOrder

public final int compareOrder(NodeInfo other)

Determine the relative position of this node and another node, in document order. The other node will always be in the same document.

Specified by:

compareOrder in interface NodeInfo

Specified by:

compareOrder in class AbstractNode

Parameters:

other - The other node, whose position is to be compared with this node

Returns:

-1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())

getEnumeration

public AxisEnumeration getEnumeration(byte axisNumber,
                                      NodeTest nodeTest)

Return an enumeration over the nodes reached by the given axis from this node

Specified by:

getEnumeration in interface NodeInfo

Specified by:

getEnumeration in class AbstractNode

Parameters:

axisNumber - Identifies the required axis, eg. Axis.CHILD or Axis.PARENT

nodeTest - A pattern to be matched by the returned nodes

Returns:

a AxisEnumeration that scans the nodes reached by the axis in turn.

hasChildNodes

public boolean hasChildNodes()

Determine whether the node has any children.

Specified by:

hasChildNodes in interface Node

Specified by:

hasChildNodes in class AbstractNode

Returns:

true if this node has any attributes, false otherwise.

hasAttributes

public boolean hasAttributes()

Returns whether this node has any attributes.

Specified by:

hasAttributes in interface Node

Specified by:

hasAttributes in class AbstractNode

Returns:

true if this node has any attributes, false otherwise.

getAttributeValue

public java.lang.String getAttributeValue(java.lang.String uri,
                                          java.lang.String localName)

Find the value of a given attribute of this node.
This method is defined on all nodes to meet XSL requirements, but for nodes other than elements it will always return null.

Specified by:

getAttributeValue in interface NodeInfo

Specified by:

getAttributeValue in class AbstractNode

Parameters:

uri - the namespace uri of an attribute

localName - the local name of an attribute

Returns:

the value of the attribute, if it exists, otherwise null

getAttributeValue

public java.lang.String getAttributeValue(int fingerprint)

Get the value of a given attribute of this node

Specified by:

getAttributeValue in interface NodeInfo

Specified by:

getAttributeValue in class AbstractNode

Parameters:

fingerprint - The fingerprint of the attribute name

Returns:

the attribute value if it exists or null if not

getDocumentRoot

public DocumentInfo getDocumentRoot()

Get the root (document) node

Specified by:

getDocumentRoot in interface NodeInfo

Overrides:

getDocumentRoot in class AbstractNode

Returns:

the DocumentInfo representing the containing document

outputNamespaceNodes

public void outputNamespaceNodes(Outputter out,
                                 boolean includeAncestors)
                          throws TransformerException

Output all namespace nodes associated with this element. Does nothing if the node is not an element.

Specified by:

outputNamespaceNodes in interface NodeInfo

Overrides:

outputNamespaceNodes in class AbstractNode

Parameters:

out - The relevant outputter

includeAncestors - True if namespaces declared on ancestor elements must be output; false if it is known that these are already on the result tree

TransformerException
