Class AttributeImpl

Implemented Interfaces:
Attr, DOMLocator, Node, NodeInfo, Source, SourceLocator

(package private) final class AttributeImpl
extends NodeImpl
implements Attr

A node in the XML parse tree representing an attribute. Note that this is generated only "on demand", when the attribute is selected by a select pattern.

Constructor Details

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 Details

copy

public void copy(Outputter out)
            throws TransformerException
Copy this node to a given outputter
Specified by:
copy in interface NodeInfo

generateId

public 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 interface NodeImpl

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 interface NodeImpl

getNextInDocument

public NodeImpl getNextInDocument(NodeImpl anchor)
Get the next node in document order (skipping attributes)
Overrides:
getNextInDocument in interface NodeImpl

getNextSibling

public Node getNextSibling()
Get next sibling - not defined for attributes
Overrides:
getNextSibling in interface NodeImpl

getNodeType

public final short getNodeType()
Return the type of node.
Specified by:
getNodeType in interface NodeInfo
Returns:
Node.ATTRIBUTE

getPreviousInDocument

public NodeImpl getPreviousInDocument()
Get the previous node in document order (skipping attributes)
Overrides:
getPreviousInDocument in interface NodeImpl

getPreviousSibling

public Node getPreviousSibling()
Get previous sibling - not defined for attributes
Overrides:
getPreviousSibling in interface NodeImpl

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 interface NodeImpl

getStringValue

public String getStringValue()
Return the character value of the node.
Specified by:
getStringValue in interface NodeInfo
Returns:
the attribute value

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 interface NodeImpl
Returns:
true if this Node object and the supplied Node object represent the same node in the tree.
