    • Method Detail

      • equals

        public boolean equals​(java.lang.Object obj)
        Overrides:
        equals in class Value

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class Value

      • setDefaultValue

        public void setDefaultValue​(Value value)
        Sets the default value of this reference.
        Parameters:
        value - the default value.

      • evaluate

        public java.lang.String evaluate​(java.util.Map symbolTable)
                          throws RslEvaluationException
        Evaluates the variable reference with the specified symbol table. The value of the reference is first looked up in the symbol table. If not found, then the default value is used. If the default value is not specified, the reference is evaluated to an empty string.
        Overrides:
        evaluate in class Value
        Parameters:
        symbolTable - the symbol table to evaluate the variabled reference against.
        Returns:
        an evaluated string.
        Throws:
        RslEvaluationException - If an error occured during rsl evaluation.

      • toRSL

        public void toRSL​(java.lang.StringBuffer buf,
                  boolean explicitConcat)
        Produces a RSL representation of this variable reference.
        Overrides:
        toRSL in class Value
        Parameters:
        buf - buffer to add the RSL representation to.
        explicitConcat - if true explicit concatination will be used in RSL strings.

      • getCompleteValue
