  • Method Details

    • setSystemId

      public void setSystemId(String uri)
      Description copied from class: TinyNodeImpl
      Set the system id of this node.
      This method is present to ensure that the class implements the javax.xml.transform.Source interface, so a node can be used as the source of a transformation.
      Specified by:
      setSystemId in interface Source
      Overrides:
      setSystemId in class TinyNodeImpl
    • 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
      Returns:
      the sequence number
    • getNodeKind

      public final int getNodeKind()
      Return the type of node.
      Returns:
      Node.ATTRIBUTE

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

    • 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.

      Overrides:
      getPrefix in class TinyNodeImpl
      Returns:
      the prefix part of the name. For an unnamed node, return null.
    • getDisplayName

      public String getDisplayName()

      Specified by:
      getDisplayName in interface NodeInfo
      Overrides:
      getDisplayName in class TinyNodeImpl

      Specified by:
      getLocalPart in interface NodeInfo
      Overrides:
      getLocalPart in class TinyNodeImpl

      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 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).

      For elements and attributes, this is the type annotation as defined in XDM. For document nodes, it should be one of XS_UNTYPED if the document has not been validated, or XS_ANY_TYPE if validation has taken place (that is, if any node in the document has an annotation other than Untyped or UntypedAtomic).

    • getSchemaType

      public SchemaType getSchemaType()
      Get the type annotation of this node, if any. The type annotation is represented as SchemaType object.

      Types derived from a DTD are not reflected in the result of this method.

      Specified by:
      getSchemaType in interface NodeInfo
      Overrides:
      getSchemaType in class TinyNodeImpl
      Returns:
      For element and attribute nodes: the type annotation derived from schema validation (defaulting to xs:untyped and xs:untypedAtomic in the absence of schema validation). For comments, text nodes, processing instructions, and namespaces: null. For document nodes, either xs:untyped if the document has not been validated, or xs:anyType if it has.
      Since:
      9.4
    • atomize

      public Value<? extends AtomicValue> atomize() throws XPathException
      Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.
      Returns:
      the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.
      Throws:
      XPathException - if the node has no typed value, for example if it is an element node with element-only content
      Since:
      8.5
    • getTypedValue

      public SequenceIterator getTypedValue() throws XPathException
      Get the typed value of the item.

      For a node, this is the typed value as defined in the XPath 2.0 data model. Since a node may have a list-valued data type, the typed value is in general a sequence, and it is returned in the form of a SequenceIterator.

      If the node has not been validated against a schema, the typed value will be the same as the string value, either as an instance of xs:string or as an instance of xs:untypedAtomic, depending on the node kind.

      For an atomic value, this method returns an iterator over a singleton sequence containing the atomic value itself.

      Returns:
      an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.
      Throws:
      XPathException - where no typed value is available, for example in the case of an element with complex content
      Since:
      8.4
    • 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:
      buffer - Buffer to contain the generated ID value
    • copy

      public void copy(Receiver out, int copyOptions, int locationId) throws XPathException
      Copy this node to a given outputter
      Parameters:
      out - the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.
      copyOptions - a selection of the options defined in CopyOptions
      locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information
      Throws:
      XPathException - if any downstream error occurs

      Specified by:
      getLineNumber in interface NodeInfo
      Specified by:
      getLineNumber in interface SourceLocator
      Overrides:
      getLineNumber in class TinyNodeImpl
      Returns:
      the line number of the node in its original source document; or -1 if not available
    • getColumnNumber

      public int getColumnNumber()
      Get the column number of the node within its source document entity

      the column number of the node in its original source document; or -1 if not available
    • isNilled

      public boolean isNilled()
      Determine whether the node has the is-nilled property
      Specified by:
      isNilled in interface NodeInfo
      Overrides:
      isNilled in class TinyNodeImpl
      Returns:
      true if the node has the is-nilled property
    • isId

      public boolean isId()
      Determine whether this node has the is-id property
      Specified by:
      isId in interface NodeInfo

      Returns:
      true if the node is an ID
    • isIdref

      public boolean isIdref()

      isIdref in interface NodeInfo
      Overrides:
      isIdref in class TinyNodeImpl
      Returns:
      true if the node is an IDREF or IDREFS element or attribute
    • hashCode

      public 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()
      Specified by:
      hashCode in interface NodeInfo
      Overrides:
      hashCode in class TinyNodeImpl
      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.
