- - ### Constructor Detail

    - #### RuleManager

          public RuleManager(NamePool pool)

      create a RuleManager and initialise variables

  - ### Method Detail

    - #### setStandaloneContext

          public void setStandaloneContext(StandaloneContext context)

      Set the standalone context for XPath expressions and patterns. This is used only for expressions and patterns occurring outside the context of a stylesheet.

    - #### getStandaloneContext

          public StandaloneContext getStandaloneContext()

      Get the standalone context for XPath expressions and patterns. This is used only for expressions and patterns occurring outside the context of a stylesheet.
      Returns:
        the StandaloneContext associated with this RuleManager. Creates a new one if none has been set explicitly.

    - #### resetHandlers

          public void resetHandlers()

      Set up a new table of handlers.

    - #### getMode

          public Mode getMode(int modeNameCode)

      Get the Mode object for a named mode. If there is not one already registered. a new Mode is created.
      Parameters:
        `modeNameCode` - The name code of the mode. Supply -1 to get the default mode.

    - #### setHandler

          public void setHandler(java.lang.String pattern,
                        NodeHandler eh)
                          throws XPathException

      Register a handler for a particular pattern. This is a convenience interface that calls setHandler(pattern, eh, mode, precedence) with default mode and precedence.
      Parameters:
        `pattern` - A match pattern
        `eh` - The NodeHandler to be used
      Throws:
        `XPathException`
      See Also:
        `NodeHandler`, `Pattern`

    - #### setHandler

          public void setHandler(Pattern pattern,
                        NodeHandler eh,
                        Mode mode,
                        int precedence)

      Register a handler for a particular pattern. The priority of the rule is the default priority for the pattern, which depends on the syntax of the pattern suppllied.
      Parameters:
        `pattern` - A match pattern
        `eh` - The ElementHandler to be used
        `mode` - The processing mode
        `precedence` - The import precedence (use 0 by default)

    - #### setHandler

          public void setHandler(Pattern pattern,
                        NodeHandler eh,
                        Mode mode,
                        int precedence,
                        double priority)

      Register a handler for a particular pattern.
      Parameters:
        `pattern` - Must be a valid Pattern.
        `eh` - The ElementHandler to be used
        `mode` - The processing mode to which this element handler applies
        `precedence` - The import precedence of this rule
        `priority` - The priority of the rule: if an element matches several patterns, the one with highest priority is used
      See Also:
        `NodeHandler`, `Pattern`

    - #### getHandler

          public NodeHandler getHandler(NodeInfo node,
                               Context c)
