Class MultipleNodeKindTest

  • All Implemented Interfaces:
    NodePredicate, ItemType, ItemTypeWithSequenceTypeCache

    public final class MultipleNodeKindTest
    extends NodeTest
    An MultipleNodeKindTest is a nodetest that matches nodes belonging to any subset of possible node kinds, for example element and document nodes, or attribute and namespace nodes
    • Constructor Detail

      • MultipleNodeKindTest

        public MultipleNodeKindTest​(UType u)
    • Method Detail

      • getUType

        public UType getUType()
        Get the corresponding UType. A UType is a union of primitive item types.
        the smallest UType that subsumes this item type
      • matches

        public boolean matches​(int nodeKind,
                               NodeName name,
                               SchemaType annotation)
        Test whether this node test is satisfied by a given node. This method is only fully supported for a subset of NodeTests, because it doesn't provide all the information needed to evaluate all node tests. In particular (a) it can't be used to evaluate a node test of the form element(N,T) or schema-element(E) where it is necessary to know whether the node is nilled, and (b) it can't be used to evaluate a node test of the form document-node(element(X)). This in practice means that it is used (a) to evaluate the simple node tests found in the XPath 1.0 subset used in XML Schema, and (b) to evaluate node tests where the node kind is known to be an attribute.
        Specified by:
        matches in class NodeTest
        nodeKind - The kind of node to be matched
        name - identifies the expanded name of the node to be matched. The value should be null for a node with no name.
        annotation - The actual content type of the node
        true if the node matches this node test
      • getMatcher

        public IntPredicateProxy getMatcher​(NodeVectorTree tree)
        Description copied from class: NodeTest
        Get a matching function that can be used to test whether numbered nodes in a TinyTree or DominoTree satisfy the node test. (Calling this matcher must give the same result as calling matchesNode(tree.getNode(nodeNr)), but it may well be faster).
        getMatcher in class NodeTest
        tree - the tree against which the returned function will operate
        an IntPredicate; the matches() method of this predicate takes a node number as input, and returns true if and only if the node identified by this node number matches the node test.
      • test

        public boolean test​(NodeInfo node)
        Test whether this node test is satisfied by a given node. This alternative method is used in the case of nodes where calculating the fingerprint is expensive, for example DOM or JDOM nodes.
        Specified by:
        test in interface NodePredicate
        test in class NodeTest
        node - the node to be matched
        true if the node test is satisfied by the supplied node, false otherwise
      • getDefaultPriority

        public double getDefaultPriority()
        Determine the default priority to use if this pattern appears as a match pattern for a template with no explicit priority attribute.
        Specified by:
        getDefaultPriority in interface ItemType
        Specified by:
        getDefaultPriority in class NodeTest
        the default priority for the pattern
      • toString

        public java.lang.String toString()
        toString in class java.lang.Object
      • toExportString

        public java.lang.String toExportString()
        Description copied from interface: ItemType
        Return a string representation of this ItemType suitable for use in stylesheet export files. This differs from the result of toString() in that it will not contain any references to anonymous types. Note that it may also use the Saxon extended syntax for union types and tuple types. The default implementation returns the result of calling toString().
        the string representation as an instance of the XPath SequenceType construct
      • hashCode

        public int hashCode()
        Returns a hash code value for the object.
        hashCode in class java.lang.Object
      • equals

        public boolean equals​(java.lang.Object obj)
        equals in class java.lang.Object
