Annotations availabe:

1. @ParamRequired - annotated field must be present (null or empty = invalid)
2. @ParamOptional - annotated field is optional (null or empty = valid) else must match regex or rule

Simple usage

class Foo {

    @ParamRequired
    String title;

    @ParamOptional
    String description;
    
}

  Foo foo = new Foo();
  ValidationProcessor.isValid(foo); // fail
  
  foo.title = "title";
  ValidationProcessor.isValid(foo); // success

Using regex and ValidatorRule

class Credentials {

    @ParamRequired(rule = ValidatorRule.EMAIL)
    String email;

    @ParamRequired(rule = ValidatorRule.PASSWORD_6_CHAR)
    String password;
    
    @ParamOptional(rule = ValidatorRule.DATE_DD_MM_YYYY)
    String date;
    
    @ParamOptional(regex = "^\+?[\d\s]{3,}$")
    String phoneNumber;
    
}

  Credentials credentials = new Credentials();
  credentials.email = "abcd@mail.com";    // valid
  credentials.password = "123456"; // valid
  credentials.date = "02/12/2018"; // valid
  // credentials.date = "1234" // invalid
  ValidationProcessor.isValid(credentials); // success
