How to use

Creation of a Format Validator Instance

1. Create a List to hold all rules to be added to the Format Validator Object

   List<LineValidationRule> lineValidationRules = new ArrayList<>();

2. Start defining validation rules and add them to the list

   Line validation rules

   • Existing validation rule for Line length. In this example it is being create a rule to validate the length of the line is equal to 10

     LineValidationRule lengthValidation = new LineLengthValidationRule(10); lineValidationRules.add(lengthValidation);

   • Existing validation rule to verify is the text line has a certain field separator. In this example the rule is being defined to verify for pipe "|" separator

     LineFieldSeparatorValidationRule pipeSeparatorValidationRule = new LineFieldSeparatorValidationRule("|"); lineValidationRules.add(pipeSeparatorValidationRule);

3. Create the FileValidator by passing the list of validation rules to constructor

   FileValidator validator = new FileValidator(lineValidationRules);

4. Validate the file by passing the filePath to the validate method

   validator.validate("fileToValidate.txt")
