Constructor Detail

AttributeImpl

public AttributeImpl(ElementImpl element,
                     int index)

Construct an Attribute node for the n'th attribute of a given element

Parameters:

element - The element containing the relevant attribute

index - The index position of the attribute starting at zero

Method Detail

getNameCode

public int getNameCode()

Get the name code, which enables the name to be located in the name pool

Specified by:

getNameCode in interface NodeInfo

Overrides:

getNameCode in class NodeImpl

See Also:

allocate, getFingerprint

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.

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

getNodeType

public final short getNodeType()

Return the type of node.

Specified by:

getNodeType in interface NodeInfo

Specified by:

getNodeType in interface org.w3c.dom.Node

Returns:

Node.ATTRIBUTE

getStringValue

public java.lang.String getStringValue()

Return the character value of the node.

Specified by:

getStringValue in interface NodeInfo

Returns:

the attribute value

getNextSibling

public org.w3c.dom.Node getNextSibling()

Get next sibling - not defined for attributes

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 attributes

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 attributes)

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 attributes)

Overrides:

getNextInDocument in class NodeImpl

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 attribute name 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

Specified by:

copy in interface NodeInfo

Throws:

javax.xml.transform.TransformerException
