  • 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 NodeInfo
      Specified by:
      setSystemId in interface Source
      Overrides:
      setSystemId in class TinyNodeImpl
    • getSystemId

      public String getSystemId()
      Description copied from class: TinyNodeImpl
      Get the system ID for the entity containing the node.
      Specified by:
      getSystemId in interface Location
      Specified by:
      getSystemId in interface Locator
      Specified by:
      getSystemId in interface NodeInfo
      Specified by:
      getSystemId in interface Source
      Specified by:
      getSystemId in interface SourceLocator
      Overrides:
      getSystemId in class TinyNodeImpl
      Returns:
      the System Identifier of the entity in the source document containing the node, or null if not known or not applicable.
    • getParent

      public TinyNodeImpl 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 int getNodeKind()
      Return the type of node.
      Returns:
      Node.ATTRIBUTE
      See Also:
    • getUnicodeStringValue

      the attribute value
    • 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
      Returns:
      the name code

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

      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.

      getNamespaceUri in interface NodeInfo
      Overrides:
      getNamespaceUri in class TinyNodeImpl
      Returns:
      The URI of the namespace of this node. For the default namespace, return an empty string
    • hasURI

      public boolean hasURI(NamespaceUri ns)
      Description copied from class: TinyNodeImpl

      Returns:
      true if the namespace of the node is the same as the alleged namespace URI
    • 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 AtomicSequence atomize() throws XPathException
      Get the typed value.
      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

      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-null, identifies the location of the instruction that requested this copy. If null, indicates that the location information is not available

      true if the node has the is-nilled property
    • isDefaultedAttribute

      public boolean isDefaultedAttribute()
      Ask whether the attribute results from expansion of attribute defaults
      Returns:
      true if this attribute resulted from expansion of default or fixed values defined in a schema. Note that this property will only be set if both the configuration properties FeatureKeys.EXPAND_ATTRIBUTE_DEFAULTS and FeatureKeys.MARK_DEFAULTED_ATTRIBUTES are set.
    • 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.
