Class NodeKindTest

  • All Implemented Interfaces:
    java.io.Serializable, ItemType

    public class NodeKindTest
    extends NodeTest
    NodeTest is an interface that enables a test of whether a node has a particular name and kind. A NodeKindTest matches the node kind only.

    • Method Detail

      • makeNodeKindTest

        public static NodeTest makeNodeKindTest​(int kind)
        Make a test for a given kind of node
      • matches

        public boolean matches​(int nodeKind,
                               int fingerprint,
                               int annotation)
        Test whether this node test is satisfied by a given node
        Specified by:
        matches in class NodeTest
        Parameters:
        nodeKind - The type of node to be matched
        fingerprint - identifies the expanded name of the node to be matched
        annotation - The actual content type of the node
      • matches

        public boolean matches​(TinyTree tree,
                               int nodeNr)
        Test whether this node test is satisfied by a given node on a TinyTree. The node must be a document, element, text, comment, or processing instruction node. This method is provided so that when navigating a TinyTree a node can be rejected without actually instantiating a NodeInfo object.
        Specified by:
        matches in class NodeTest
        Parameters:
        tree - the TinyTree containing the node
        nodeNr - the number of the node within the TinyTree
        Returns:
        true if the node matches the NodeTest, otherwise false
      • matches

        public boolean matches​(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:
        matches in class NodeTest
        Parameters:
        node - the node to be matched
      • getDefaultPriority

        public final double getDefaultPriority()
        Determine the default priority of this node test when used on its own as a Pattern
        Specified by:
        getDefaultPriority in class NodeTest
      • getPrimitiveType

        public int getPrimitiveType()
        Determine the types of nodes to which this pattern applies. Used for optimisation.
        Specified by:
        getPrimitiveType in interface ItemType
        Overrides:
        getPrimitiveType in class NodeTest
        Returns:
        the type of node matched by this pattern. e.g. Type.ELEMENT or Type.TEXT
      • getNodeKindMask

        public int getNodeKindMask()
        Get a mask indicating which kinds of nodes this NodeTest can match. This is a combination of bits: 1<
        Specified by:
        getNodeKindMask in class NodeTest
      • getContentType

        public SchemaType getContentType()
        Get the content type allowed by this NodeTest (that is, the type of content allowed). Return AnyType if there are no restrictions.
        Overrides:
        getContentType in class NodeTest
      • getAtomizedItemType

        public AtomicType getAtomizedItemType()
        Get the content type allowed by this NodeTest (that is, the type annotation). Return AnyType if there are no restrictions. The default implementation returns AnyType.
        Specified by:
        getAtomizedItemType in interface ItemType
        Overrides:
        getAtomizedItemType in class NodeTest
      • toString

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

        public static java.lang.String toString​(int kind)
      • hashCode

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

        public boolean equals​(java.lang.Object other)
        Indicates whether some other object is "equal to" this one.
        Overrides:
        equals in class java.lang.Object
