Constructor Detail

### DocumentNodeTest

    public DocumentNodeTest(NodeTest elementTest)

Method Detail

### 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)

  Determine whether this Pattern matches the given Node.

  Specified by:
    `matches` in class `NodeTest`
  Parameters:
    `node` - The NodeInfo representing the Element or other node to be tested against the Pattern uses variables, or contains calls on functions such as document() or key().
  Returns:
    true if the node matches the Pattern, false otherwise

### 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`

### getElementTest

    public NodeTest getElementTest()

  Get the element test contained within this document test

  Returns:
    the contained element test

### toString

    public String toString(NamePool pool)

  Description copied from class: `NodeTest`
  Display the type descriptor for diagnostics

  Specified by:
    `toString` in interface `ItemType`
  Overrides:
    `toString` in class `NodeTest`

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`

### hashCode

    public int hashCode()

  Returns a hash code value for the object.

  Overrides:
    `hashCode` in class `Object`

### equals

    public boolean equals(Object other)

  Overrides:
    `equals` in class `Object`
