Interface ValidationStrategy<T>

Type Parameters:

T - The type of the value to be validated.

All Known Implementing Classes:

AbstractValidationStrategy, BeanTools.NonNullPropertyChangeEventValidator, NonEmptyStringValidationStrategy, NonNullClassValidationStrategy, NonNullNonEmptyStringValidationStrategy, NonNullObjectValidationStrategy, NonNullStringValidationStrategy, NonNullValidationStrategy, NoValidationStrategy, RangeValidationStrategy

public interface ValidationStrategy<T>

A strategy for validating a value. To facilitate validator reuse, it is strongly suggested that such strategies be thread-safe, furthermore they should be stateless as well.

Method Detail

validate

void validate(T unvalidated,
              Object... context)

Validates the specified value.

Parameters:

unvalidated - The value to be validated. May not be null.

context - Any information required for, or related to, the validation of unvalidated. The semantics (including whether null-ness is permitted) of this parameter are defined by the implementations of this method. The first contextual argument is, by convention, a String containing a description of the value being validated.

Throws:

ValidationException - Iff unvalidated is invalid or cannot be validated because context is insufficient.
