public abstract class TinyNodeImpl extends Object implements NodeInfo, FingerprintedNode, SourceLocator
This is the top-level class in the implementation class hierarchy; it essentially contains all those methods that can be defined using other primitive methods, without direct access to data.

---|---|
protected int | nodeNr |
static char[] | NODE_LETTER
Chararacteristic letters to identify each type of node, indexed using the node type
values. |
protected TinyNodeImpl | parent |
protected TinyTree | tree |
Method Summary | |
---|---|
Value | atomize()
Get the typed value. |
int | compareOrder(NodeInfo other)
Determine the relative position of this node and another node, in document order.
|
boolean | equals(Object other)
The equals() method compares nodes for identity. |

Get a character string that uniquely identifies this node
|
String | getAttributeValue(int fingerprint)

int | getColumnNumber()
Get the column number of the node.
|
Configuration | getConfiguration()
Get the configuration |
int[] | getDeclaredNamespaces(int[] buffer)
Get all namespace undeclarations and undeclarations defined on this element.
|
String | getDisplayName()
Get the display name of this node (a lexical QName). |
int | getDocumentNumber()
Get the document number of the document containing this node
(Needed when the document isn't a real node, for sorting free-standing elements) |
DocumentInfo | getDocumentRoot()
Get the root (document) node
|
int | getFingerprint()
Get the fingerprint of the node, used for matching names |
int | getLineNumber()
Get the line number of the node within its source document entity |
String | getLocalPart()
Get the local part of the name of this node.
|
int | getNameCode()
Get the name code of the node, used for matching names |
NamePool | getNamePool()
Get the NamePool for the tree containing this node
|
NodeInfo | getParent()
Find the parent node of this node.
|
static int | getParentNodeNr(TinyTree tree, int nodeNr)
Static method to get the parent of a given node, without instantiating the node as an object.
|
String | getPrefix()
Get the prefix part of the name of this node. |
String | getPublicId()
Get the public identifier of the document entity containing this node.
|
NodeInfo | getRoot()
Get the root node of the tree (not necessarily a document node)
|
protected long | getSequenceNumber()
Get the node sequence number (in document order). |
CharSequence | getStringValueCS()
Get the value of the item as a CharSequence. |
String | getSystemId()
Get the system ID for the entity containing the node. |
int | getTypeAnnotation()
Get the type annotation of this node, if any |
SequenceIterator | getTypedValue()
Get the typed value of this node.
|
String | getURI()
Get the URI part of the name of this node. |
boolean | hasChildNodes()
Determine whether the node has any children.
|
int | hashCode()
The hashCode() method obeys the contract for hashCode(): that is, if two objects are equal
(represent the same node) then they must have the same hashCode()
|
boolean | isAncestorOrSelf(TinyNodeImpl d)
Test if this node is an ancestor-or-self of another
|
boolean | isSameNodeInfo(NodeInfo other)
Determine whether this is the same node as another node
|
AxisIterator | iterateAxis(byte axisNumber)
Return an iterator over all the nodes reached by the given axis from this node
|
AxisIterator | iterateAxis(byte axisNumber, NodeTest nodeTest)
Return an iterator over the nodes reached by the given axis from this node
|
void | sendNamespaceDeclarations(Receiver out, boolean includeAncestors)
Output all namespace nodes associated with this element. |
protected void | setParentNode(TinyNodeImpl parent)
Set the parent of this node. |
void | setSystemId(String uri)
Set the system id of this node. |
Returns: the typed value. If requireSingleton is set to true, the result will always be an AtomicValue. In other cases it may be a Value representing a sequence whose items are atomic values.
Since: 8.5
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())
Parameters: other the node to be compared with this node
Returns: true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree.
Since: 8.7 Previously, the effect of the equals() method was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics. It is safer to use isSameNodeInfo() for this reason. The equals() method has been defined because it is useful in contexts such as a Java Set or HashMap.
Parameters: buffer buffer, which on return will contain a character string that uniquely identifies this node.
Parameters: fingerprint The fingerprint of the attribute name
Returns: the attribute value if it exists or null if not
Parameters: buffer If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
Returns: An array of integers representing the namespace declarations and undeclarations present on
this element. For a node other than an element, return null. Otherwise, the returned array is a
sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The
top half word of each namespace code represents the prefix, the bottom half represents the URI.
If the bottom half is zero, then this is a namespace undeclaration rather than a declaration.
The XML namespace is never included in the list. If the supplied array is larger than required,
then the first unused entry will be set to -1.
For a node other than an element, the method returns null.
Returns: The display name of this node. For a node with no name, return an empty string.
Returns: the DocumentInfo representing the containing document
Returns: The local name of this node. For a node with no name, return "".
Returns: the NamePool
Returns: The Node object describing the containing element or root node.
Parameters: tree the tree containing the starting node nodeNr the node number of the starting node within the tree
Returns: the node number of the parent node, or -1 if there is no parent.
Returns: the prefix part of the name. For an unnamed node, return "".
Returns: the NodeInfo representing the root of this tree
Returns: The URI of the namespace of this node. For an unnamed node, or for an element or attribute in the default namespace, return an empty string.
Returns: true
if this node has any attributes,
false
otherwise.
Since: 8.7 Previously, the effect of the equals() and hashCode() methods was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics.
Parameters: d the putative descendant-or-self node
Returns: true if this node is an ancestor-or-self of d
Returns: true if this Node object and the supplied Node object represent the same node in the tree.
Parameters: axisNumber Identifies the required axis, eg. Axis.CHILD or Axis.PARENT
Returns: a AxisIteratorImpl that scans the nodes reached by the axis in turn.
Parameters: axisNumber Identifies the required axis, eg. Axis.CHILD or Axis.PARENT nodeTest A pattern to be matched by the returned nodes.
Returns: a AxisIteratorImpl that scans the nodes reached by the axis in turn.
Parameters: out The relevant outputter includeAncestors True if namespaces declared on ancestor elements must
