## net.sf.saxon.pattern
Class NamespaceTest

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

All Implemented Interfaces:
  ItemType, java.io.Serializable

public final class NamespaceTest
extends NodeTest

NodeTest is an interface that enables a test of whether a node has a particular name and type. A NamespaceTest matches the node type and the namespace URI.

Method Summary
`boolean` | `equals(java.lang.Object other)` Indicates whether some other object is "equal to" this one.
`double` | `getDefaultPriority()` Determine the default priority of this node test when used on its own as a Pattern
`int` | `getNodeKindMask()` Get a mask indicating which kinds of nodes this NodeTest can match.
`int` | `getPrimitiveType()` Determine the types of nodes to which this pattern applies.
`ItemType` | `getSuperType(TypeHierarchy th)` Get the type from which this item type is derived by restriction.
`int` | `hashCode()` Returns a hash code value for the object.
`boolean` | `matches(int nodeType, int fingerprint, int annotation)` Test whether this node test is satisfied by a given node
`boolean` | `matches(NodeInfo node)` Test whether this node test is satisfied by a given node.
`boolean` | `matches(TinyTree tree, int nodeNr)` Test whether this node test is satisfied by a given node on a TinyTree.

Constructor Detail

### NamespaceTest

    public NamespaceTest(NamePool pool,
                         int nodeKind,
                         java.lang.String uri)

Method Detail

### matches

    public 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`

### getPrimitiveType

    public int getPrimitiveType()

  Determine the types of nodes to which this pattern applies. Used for optimisation. For patterns that match nodes of several types, return Type.NODE

  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

### getSuperType

    public ItemType getSuperType(TypeHierarchy th)

  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 xdt: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`
  Parameters:
    `th` -
  Returns:
    the supertype, or null if this type is item()

### 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 java.lang.String toString()

### hashCode

    public int hashCode()

  Returns a hash code value for the object.

### equals

    public boolean equals(java.lang.Object other)

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