public boolean apply(Class<?> type,
                     Object value,
                     List<ValidationFailure> validationFailures)

Apply validation for the given field. If the field is not of a type in the list returned by getTypeClasses, the validation is not applied and this method returns false. If the type is in the list, then the validate method is called to see if the value is of a type that can be applied to the given field type. Errors are appended to the validationFailures list.

Parameters:

type - the Class of the field being queried

value - the value being used for a query

validationFailures - the list to add any failures to. If validation passes or appliesTo returned false, this list will not change.

Returns:

true if validation was applied, false if this validation doesn't apply to this field type.
