          public org.apache.xalan.xsltc.compiler.QName getQName(java.lang.String namespace,
                                                       java.lang.String prefix,
                                                       java.lang.String localname)

    - #### setMultiDocument

          public void setMultiDocument(boolean flag)

    - #### setCallsNodeset

          public void setCallsNodeset(boolean flag)

    - #### setHasIdCall

          public void setHasIdCall(boolean flag)

    - #### createStepPattern

          public org.apache.xalan.xsltc.compiler.StepPattern createStepPattern(int axis,
                                                                      java.lang.Object test,
                                                                      java.util.Vector predicates)

      This method is similar to findNodeType(int, Object) except that it creates a StepPattern instead of just returning a node type. It also differs in the way it handles "{uri}:*" and "{uri}:@*". The last two patterns are expanded as "*[namespace-uri() = 'uri']" and "@*[namespace-uri() = 'uri']", respectively. This expansion considerably simplifies the grouping of patterns in the Mode class. For this expansion to be correct, the priority of the pattern/template must be set to -0.25 (when no other predicates are present).

    - #### findNodeType

          public int findNodeType(int axis,
                         java.lang.Object test)

    - #### parse

          public java_cup.runtime.Symbol parse(java.lang.String expression,
                                      int lineNumber)
                                        throws java.lang.Exception

      Parse the expression passed to the current scanner. If this expression contains references to local variables and it will be compiled in an external module (not in the main class) request the current template to create a new variable stack frame.
      Parameters:
        `lineNumber` - Line where the current expression is defined.
        `external` - Set to `true` if this expression is compiled in a separate module.
      Throws:
        `java.lang.Exception`

    - #### addError

          public final void addError(ErrorMsg error)

    - #### report_error

          public void report_error(java.lang.String message,

    - #### report_fatal_error

          public void report_fatal_error(java.lang.String message,
                                java.lang.Object info)

      Overrides:
        `report_fatal_error` in class `java_cup.runtime.lr_parser`

    - #### insertStep

          public org.apache.xalan.xsltc.compiler.RelativeLocationPath insertStep(org.apache.xalan.xsltc.compiler.Step step,
                                                                        org.apache.xalan.xsltc.compiler.RelativeLocationPath rlp)

    - #### isElementAxis

          public boolean isElementAxis(int axis)

      Returns true if the axis applies to elements only. The axes child, attribute, namespace, descendant result in non-empty nodesets only if the context node is of type element.
