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

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object

      • setValue

        public void setValue​(java.lang.String value)
        Sets the actual value.
        Parameters:
        value - the new value.

      • getValue

        public java.lang.String getValue()
        Returns the actual string value.
        Returns:
        the current value.

      • getConcat

        public Value getConcat()
        Returns the value that is concatinated with this value.
        Returns:
        the value that is concatinated with this value. Null, otherwise.

      • concat

        public void concat​(Value value)
        Appends the specified value to the end of the chain of concatinated values. That is, if this value has no concatinated value then set the specified value as the concatinated value. If this value already has a concatinated value then append the specified value to that concatinated value.
        Parameters:
        value - the value to concatinate.

      • evaluate

        public java.lang.String evaluate​(java.util.Map symbolTable)
                          throws RslEvaluationException
        Evaluates the value with the specified symbol table. In this case the function just returns the string representation of the actual value. No symbol table lookups are performed.
        Parameters:
        symbolTable - the symbol table to evaluate the value against.
        Returns:
        an evaluated string.
        Throws:
        RslEvaluationException - If an error occured during rsl evaluation.

      • toRSL

        public java.lang.String toRSL​(boolean explicitConcat)
        Returns a RSL representation of this value.
        Parameters:
        explicitConcat - if true explicit concatination will be used in RSL strings.
        Returns:
        RSL representation of this value.

      • toRSL

        public void toRSL​(java.lang.StringBuffer buf,
                  boolean explicitConcat)
