  A pattern which matches any Text node

Constructor Detail

### NodeTypePattern

    public NodeTypePattern(short nodeType)

Method Detail

### matches

    public boolean matches(Node node)

  Description copied from interface: `Pattern`
  DOCUMENT ME!

  Specified by:
    `matches` in interface `Pattern`
  Parameters:
    `node` - DOCUMENT ME!
  Returns:
    true if the pattern matches the given DOM4J node.

### getPriority

    public double getPriority()

  Description copied from interface: `Pattern`
  Returns the default resolution policy of the pattern according to the XSLT conflict resolution spec .

  Specified by:
    `getPriority` in interface `Pattern`
  Returns:
    DOCUMENT ME!

### getUnionPatterns

    public Pattern[] getUnionPatterns()

  Description copied from interface: `Pattern`
  If this pattern is a union pattern then this method should return an array of patterns which describe the union pattern, which should contain more than one pattern. Otherwise this method should return null.

  Specified by:
    `getUnionPatterns` in interface `Pattern`
  Returns:
    an array of the patterns which make up this union pattern or null if this pattern is not a union pattern

### getMatchType

    public short getMatchType()

  Description copied from interface: `Pattern`
  DOCUMENT ME!

  Specified by:
    `getMatchType` in interface `Pattern`
  Returns:
    the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.

### getMatchesNodeName

    public String getMatchesNodeName()

  Description copied from interface: `Pattern`
  For patterns which only match an ATTRIBUTE_NODE or an ELEMENT_NODE then this pattern may return the name of the element or attribute it matches. This allows a more efficient rule matching algorithm to be performed, rather than a brute force approach of evaluating every pattern for a given Node.

  Specified by:
    `getMatchesNodeName` in interface `Pattern`
  Returns:
    the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.
