  • All Implemented Interfaces:
    javax.xml.transform.Source, javax.xml.transform.SourceLocator, ExtendedNodeInfo, FingerprintedNode, Item, NodeInfo, ValueRepresentation

    final class TinyAttributeImpl
    extends TinyNodeImpl
    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.

                                 int nodeNr)
    • Method Detail

      • getRoot

        public NodeInfo getRoot()
        Get the root node of the tree (not necessarily a document node)
        Specified by:
        getRoot in interface NodeInfo
        Overrides:
        getRoot in class TinyNodeImpl
        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 class TinyNodeImpl
      • getNodeKind

        public final int getNodeKind()
        Return the type of node.
        Returns:
        Node.ATTRIBUTE
        See Also:
        Type
      • getStringValue

        public java.lang.String getStringValue()
        Return the string value of the node.
        Returns:
        the attribute value
        See Also:
        Item.getStringValueCS()
      • getFingerprint

        public int getFingerprint()
        Get the fingerprint of the node, used for matching names
        Specified by:
        getFingerprint in interface NodeInfo
        Overrides:
        getFingerprint in class TinyNodeImpl
        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 interface NodeInfo
        Overrides:
        getNameCode in class TinyNodeImpl
        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.

        allocate, getFingerprint
      • getPrefix

        public java.lang.String getPrefix()
        Get the prefix part of the name of this node. This is the name before the ":" if any.
        Specified by:
        getPrefix in interface NodeInfo
        Overrides:
        getPrefix in class TinyNodeImpl
        Returns:
        the prefix part of the name. For an unnamed node, return null.
      • getDisplayName

        public java.lang.String 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 interface NodeInfo
        Overrides:
        getDisplayName in class TinyNodeImpl
        Returns:
        The display name of this node. For a node with no name, return an empty string.
      • getLocalPart

        public java.lang.String getLocalPart()
        Get the local name of this node.
        Specified by:
        getLocalPart in interface NodeInfo
        Overrides:
        getLocalPart in class TinyNodeImpl
        Returns:
        The local name of this node. For a node with no name, return an empty string.
      • getURI

        public final java.lang.String getURI()
        Get the URI part of the name of this node.
        Specified by:
        getURI in interface NodeInfo
        Overrides:
        getURI in class TinyNodeImpl
        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 bit NodeInfo.IS_DTD_TYPE (1<<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 interface NodeInfo
        Overrides:
        getTypeAnnotation in class TinyNodeImpl
        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

        public void generateId​(FastStringBuffer buffer)
        Generate id. Returns key of owning element with the attribute namecode as a suffix

                  throws XPathException
        Copy this node to a given outputter
        Parameters:
        out - the Receiver to which the node should be copied
        whichNamespaces - in the case of an element, controls which namespace nodes should be copied. Values are NodeInfo.NO_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.ALL_NAMESPACES
        copyAnnotations - indicates whether the type annotations of element and attribute nodes should be copied
        locationId - 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
