      • evaluate

        public static String evaluate​(org.apache.velocity.VelocityContext context,
                                      String toParse,
                                      String valueOnError)
        Parses a string containing variables who's values will be filled in based on the VelocityContext passed in.

        If there is an error parsing the string, the valueOnError is returned.

        An example string would be "Var1's value is: ${Var1}"

        context - object containing the values to replace the variables with
        toParse - the string containing the variables and arbitrary text
        valueOnError - the string to return if there is an error parsing the toParse string
        either a string based on the variable toParse string or the valueOnError if there was an error parsing the string
      • getTemplateVarNames

        public static ArrayList<String> getTemplateVarNames​(String toParse)
        Retrieves the names of the variables contained in the toParse string.
