Constructor Detail

### OrPattern

    public OrPattern(Pattern lhs,
                     Pattern rhs)

  Construct an OrPattern for the passed left-side and right-side patterns.

  Parameters:
    `lhs` - The left-hand-side pattern.
    `rhs` - The right-hand-side pattern.

Method Detail

### toString

    public String toString()

  Provide a readable description for debugging.

  Overrides:
    `toString` in class `Object`
  Returns:
    String representation

### match

    public boolean match(Node node,
                         ExpressionContext context)
                  throws XPathEvaluationException

  Return true or false depending on whether the passed node matches the XSLT Pattern or not. The passed ExpressionContext is necessary for evaluation of XPath Predicate expressions, which may be part of a Pattern, as well as for namespace resolution.

  Specified by:
    `match` in interface `Pattern`
  Parameters:
    `node` - The node to match.
    `context` - The context for matching.
  Returns:
    True if the node matches the pattern, false otherwise.
  Throws:
    `XPathEvaluationException`

### getDefaultPriority

    public double getDefaultPriority()

  Return the default priority for this pattern. See XSLT spec for information on default priority calculation.

  Specified by:
    `getDefaultPriority` in interface `Pattern`
  Returns:
    -0.5, 0.0, or 0.5

### getTarget

    public int getTarget()

  Return the target type of this Pattern. This is one of the values defined in the Pattern interface (ELEMENT_NAMED_TARGET, ELEMENT_WILDCARD_TARGET, etc.)

  Specified by:
    `getTarget` in interface `Pattern`
  Returns:
    The target type value for this Pattern.

### getTargetName

    public ExpandedQName getTargetName()

  Return the name of the patterns target, if there is a target name. This may return null if there is no target name for this pattern (text(), node(), etc.). However, if getTarget() returns ELEMENT_NAMED_TARGET or ATTRIBUTE_NAMED_TARGET this will never return null.

  Specified by:
    `getTargetName` in interface `Pattern`
  Returns:
    The target name or null.

### dump

    public void dump(PrintWriter writer,
                     int indent)

  Print the pattern in a readable form for debugging.

  Specified by:
    `dump` in interface `Pattern`
  Parameters:
    `writer` - The output device.
    `indent` - Number of tabs to indent the result.

### getPatterns

    public Pattern[] getPatterns()

  Return each alternative pattern from the OrPattern in an array of Patterns.

  Returns:
    An array of Objects implementing Pattern, one for each alternative pattern in the OrPattern.
