    Description copied from class: AbstractValidator
    
    AbstractValidator only provides a default implementation of this method.
    ATTENTION:
    This default implementation returns the simple class name of the actual Validator implementation. This strategy is chosen for simplicity when implementing a new Validator. To ensure stable IDs override this method and return a string constant. This shall at least be done when the name of the class is changed to provide backwards compatibility.
    
    Specified by:
    
    getId in interface Validator<CharSequence>
    
    Overrides:
    
    getId in class AbstractValidator<CharSequence>
    
    Returns:
    
    the identifier of this Validator.

  - validateNotNull
```
protected NlsMessage validateNotNull(CharSequence value)
```
    Description copied from class: AbstractValueValidator
    
    This method performs the validation in case value is NOT null. This method contains the actual custom logic for the validation. It is therefore designed in a way that makes it most simple to implement custom validators.
    
    Specified by:
    
    validateNotNull in class AbstractValueValidator<CharSequence>
    
    Parameters:
    
    value - the value to validate.
    
    Returns:
    
    the failure message or null if the the given value is valid.
  - get
```
public static ValidatorHost get()
```
    Returns:
    
    the instance of ValidatorHost.
