public StandardComponents(JepComponent... replacements)

Create a StandardCompents where replacement for some components are specified in the constructor.

For example for use cases where you don't need to parse or print the expression you could use.

        Jep jep = new Jep(
                new StandardComponents(
                        NullParser.NULL_PARSER, 
                        PrintVisitor.NULL_PRINT_VISITOR));
    }

 

Parameters:

replacements - set of components to use in preference.
