## net.sf.saxon.pattern
Class AnyNodeTest

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

All Implemented Interfaces:
  Serializable, ItemType

    public final class AnyNodeTest

extends NodeTest

NodeTest is an interface that enables a test of whether a node has a particular name and type. An AnyNodeTest matches any node.

Method Detail

### getInstance

    public static AnyNodeTest getInstance()

  Get an instance of AnyNodeTest

### matchesItem

    public boolean matchesItem(Item item,
                               boolean allowURIPromotion,
                               Configuration config)

  Test whether a given item conforms to this type

  Specified by:
    `matchesItem` in interface `ItemType`
  Overrides:
    `matchesItem` in class `NodeTest`
  Parameters:
    `item` - The item to be tested
    `allowURIPromotion` -
    `config` -
  Returns:
    true if the item is an instance of this type; false otherwise

### getSuperType

    public ItemType getSuperType(TypeHierarchy th)

  Description copied from class: `NodeTest`
  Get the type from which this item type is derived by restriction. This is the supertype in the XPath type heirarchy, as distinct from the Schema base type: this means that the supertype of xs:boolean is xs:anyAtomicType, whose supertype is item() (rather than xs:anySimpleType).

  In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.

  Specified by:
    `getSuperType` in interface `ItemType`
  Overrides:
    `getSuperType` in class `NodeTest`
  Returns:
    the supertype, or null if this type is item()

### matches

    public final boolean matches(int nodeType,
                                 int fingerprint,
                                 int annotation)

  Test whether this node test is satisfied by a given node

  Specified by:
    `matches` in class `NodeTest`
  Parameters:
    `nodeType` - 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`

### 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`

### 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`
