    • Method Detail

      • add

        public void add​(Binding binding)
        Adds a new variable definition to the list.
        Parameters:
        binding - a new variable definition.
      • removeVariable

        public boolean removeVariable​(java.lang.String varName)
        Removes a specific variable definition from the list of bindings. The variable name must match exactly to be removed (it is case sensitive).
        Parameters:
        varName - variable name to remove the definition of.
        Returns:
        true if the variable was successfully removed. False, otherwise.
      • evaluate

        public Bindings evaluate​(java.util.Map symbolTable)
                          throws RslEvaluationException
        Evaluates the variable definitions as variable definitions can reference each other against the symbol table. The evaluation process updates the symbol table.
        Parameters:
        symbolTable - the symbol table to evalute the variables against.
        Returns:
        a new evaluted variable definition.
        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 relation.
        Specified by:
        toRSL in class NameValue
        Parameters:
        buf - buffer to add the RSL representation to.
        explicitConcat - if true explicit concatination will be used in RSL strings.
