Method Details
-
getParent
Get the parent node- Specified by:
getParent
in interfaceNodeInfo
- Overrides:
getParent
in classTinyNodeImpl
- Returns:
- The Node object describing the containing element or root node.
-
getRoot
Get the root node of the tree (not necessarily a document node)- Specified by:
getRoot
in interfaceNodeInfo
- Overrides:
getRoot
in classTinyNodeImpl
- Returns:
- the NodeInfo representing the root of this tree
-
getSequenceNumber
protected long getSequenceNumber()Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In this implementation, elements have a zero least-significant word, while attributes and namespaces use the same value in the top word as the containing element, and use the bottom word to hold a sequence number, which numbers namespaces first and then attributes.- Overrides:
getSequenceNumber
in classTinyNodeImpl
-
getNodeKind
public final int getNodeKind()Return the type of node.- Returns:
- Node.ATTRIBUTE
- See Also:
-
getStringValueCS
Return the string value of the node.- Specified by:
getStringValueCS
in interfaceItem
- Specified by:
getStringValueCS
in interfaceValueRepresentation
- Overrides:
getStringValueCS
in classTinyNodeImpl
- Returns:
- the attribute value
- See Also:
-
getStringValue
Return the string value of the node.- Returns:
- the attribute value
- See Also:
-
getFingerprint
public int getFingerprint()Get the fingerprint of the node, used for matching names- Specified by:
getFingerprint
in interfaceNodeInfo
- Overrides:
getFingerprint
in classTinyNodeImpl
- Returns:
- an integer fingerprint; two nodes with the same fingerprint have the same expanded QName. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.
-
getNameCode
public int getNameCode()Get the name code of the node, used for finding names in the name pool- Specified by:
getNameCode
in interfaceNodeInfo
- Overrides:
getNameCode
in classTinyNodeImpl
- Returns:
- an integer name code, which may be used to obtain the actual node name from the name pool. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.
- See Also:
-
getPrefix
Get the prefix part of the name of this node. This is the name before the ":" if any.- Specified by:
getPrefix
in interfaceNodeInfo
- Overrides:
getPrefix
in classTinyNodeImpl
- Returns:
- the prefix part of the name. For an unnamed node, return null.
-
getDisplayName
Get the display name of this node. For elements and attributes this is [prefix:]localname. For unnamed nodes, it is an empty string.- Specified by:
getDisplayName
in interfaceNodeInfo
- Overrides:
getDisplayName
in classTinyNodeImpl
- Returns:
- The display name of this node. For a node with no name, return an empty string.
-
getLocalPart
Get the local name of this node.- Specified by:
getLocalPart
in interfaceNodeInfo
- Overrides:
getLocalPart
in classTinyNodeImpl
- Returns:
- The local name of this node. For a node with no name, return an empty string.
-
getURI
Get the URI part of the name of this node.- Specified by:
getURI
in interfaceNodeInfo
- Overrides:
getURI
in classTinyNodeImpl
- Returns:
- The URI of the namespace of this node. For the default namespace, return an empty string
-
getTypeAnnotation
public int getTypeAnnotation()Get the type annotation of this node, if any The bitNodeInfo.IS_DTD_TYPE
(1invalid input: '<'invalid input: '<'30) will be set in the case of an attribute node if the type annotation is one of ID, IDREF, or IDREFS and this is derived from DTD rather than schema validation. Returns UNTYPED_ATOMIC if there is no type annotation- Specified by:
getTypeAnnotation
in interfaceNodeInfo
- Overrides:
getTypeAnnotation
in classTinyNodeImpl
- Returns:
- the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the
bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated
as untypedAtomic for the purposes of obtaining the typed value).
The result is undefined for nodes other than elements and attributes.
-
generateId
Generate id. Returns key of owning element with the attribute namecode as a suffix- Specified by:
generateId
in interfaceNodeInfo
- Overrides:
generateId
in classTinyNodeImpl
- Parameters:
buffer
- Buffer to contain the generated ID value
-
copy
public void copy(Receiver out, int whichNamespaces, boolean copyAnnotations, int locationId) throws XPathException Copy this node to a given outputter- Parameters:
out
- the Receiver to which the node should be copiedwhichNamespaces
- in the case of an element, controls which namespace nodes should be copied. Values areNodeInfo.NO_NAMESPACES
,NodeInfo.LOCAL_NAMESPACES
,NodeInfo.ALL_NAMESPACES
copyAnnotations
- indicates whether the type annotations of element and attribute nodes should be copiedlocationId
- If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be a LocationCopier- Throws:
XPathException
-
getLineNumber
public int getLineNumber()Get the line number of the node within its source document entity- Specified by:
getLineNumber
in interfaceNodeInfo
- Specified by:
getLineNumber
in interfaceSourceLocator
- Overrides:
getLineNumber
in classTinyNodeImpl
- Returns:
- the line number of the node in its original source document; or -1 if not available
-
isId
public boolean isId()Determine whether this node has the is-id property- Specified by:
isId
in interfaceExtendedNodeInfo
- Overrides:
isId
in classTinyNodeImpl
- Returns:
- true if the node is an ID
-
isIdref
public boolean isIdref()Determine whether this node has the is-idref property- Specified by:
isIdref
in interfaceExtendedNodeInfo
- Overrides:
isIdref
in classTinyNodeImpl
- Returns:
- true if the node is an IDREF or IDREFS element or attribute
-
