All Implemented Interfaces:
Source, SourceLocator, ExtendedNodeInfo, FingerprintedNode, Item, NodeInfo, ValueRepresentation

final class TinyAttributeImpl extends TinyNodeImpl

      public TinyAttributeImpl(TinyTree tree, int nodeNr)
  • Method Details

    • getParent

      public NodeInfo getParent()
      Get the parent node
      Specified by:
      getParent in interface NodeInfo
      Overrides:
      getParent in class TinyNodeImpl
      Returns:
      The Node object describing the containing element or root node.
    • 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:
    • getStringValueCS

      public CharSequence getStringValueCS()
      Return the string value of the node.
      Specified by:
      getStringValueCS in interface Item
      Specified by:
      getStringValueCS in interface ValueRepresentation
      Overrides:
      getStringValueCS in class TinyNodeImpl
      Returns:
      the attribute value
      See Also:
    • getStringValue

      public String 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 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.
      See Also:
    • getPrefix

      public 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 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 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 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 (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 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
      Specified by:
      generateId in interface NodeInfo
      Overrides:
      generateId in class TinyNodeImpl
      Parameters:

    • 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 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
