## net.sf.saxon.pattern
Class NodeKindTest

    java.lang.Object
      net.sf.saxon.pattern.NodeTest
          net.sf.saxon.pattern.NodeKindTest

All Implemented Interfaces:
  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.

Field Detail

### DOCUMENT

    public static final NodeKindTest DOCUMENT

### ELEMENT

    public static final NodeKindTest ELEMENT

### ATTRIBUTE

    public static final NodeKindTest ATTRIBUTE

### TEXT

    public static final NodeKindTest TEXT

### COMMENT

    public static final NodeKindTest COMMENT

### PROCESSING_INSTRUCTION

    public static final NodeKindTest PROCESSING_INSTRUCTION

### NAMESPACE

    public static final NodeKindTest NAMESPACE

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 String toString()

  Overrides:
    `toString` in class `Object`

### toString

    public static String toString(int kind)

### hashCode

    public int hashCode()

  Returns a hash code value for the object.

  Overrides:
    `hashCode` in class `Object`

### equals

    public boolean equals(Object other)

  Indicates whether some other object is "equal to" this one.

  Overrides:
    `equals` in class `Object`
