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 attributeindex
- 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 interfaceNodeInfo
- Overrides:
getNameCode
in classNodeImpl
- See Also:
allocate
,getFingerprint
-
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.
-
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
-
getNodeType
public final short getNodeType()
Return the type of node.- Specified by:
getNodeType
in interfaceorg.w3c.dom.Node
- Specified by:
getNodeType
in interfaceNodeInfo
- Returns:
- Node.ATTRIBUTE
-
getStringValue
public java.lang.String getStringValue()
Return the character value of the node.- Specified by:
getStringValue
in interfaceNodeInfo
- Returns:
- the attribute value
-
getNextSibling
public org.w3c.dom.Node getNextSibling()
Get next sibling - not defined for attributes- 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 attributes- 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 attributes)- 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 attributes)- 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 attribute name as a suffix- Specified by:
generateId
in interfaceNodeInfo
- Overrides:
generateId
in classNodeImpl
- Returns:
- a string.
