Method Detail

addValidator

void addValidator(ValueValidator<? super V> validator)

This method adds the given ValueValidator to this object. All ValueValidators are invoked in the same order as they are added by this method. They are invoked no matter if the previous ValueValidators failed or succeeded. You should always design ValueValidators in a robust and reusable way (e.g. a range validator should accept null as valid input so it can be used for both mandatory and optional fields).

Parameters:

validator - is the ValueValidator to add.

removeValidator

boolean removeValidator(ValueValidator<? super V> validator)

This method removes the given ValueValidator from this object.
ATTENTION:
Having dynamic validators is an exotic case that should be avoided. This feature is provided but not recommended.

Parameters:

validator - is the ValueValidator to remove.

Returns:

true if the ValueValidator has actually been removed, false otherwise (it has NOT previously been added).
