Interface Validatable<T>

All Known Implementing Classes:

DefaultValidatable

public interface Validatable<T>

Encapsulates an object which can be validated.

Validatable is unaware of UI framework and contains only validation specific logic.

Usage patterns:

1. Extract value from to be-validated-component and wap it with Validatable implementation (e.g. DefaultValidatable).
2. Pass resulting validatable to all associated validators
3. Query validatable.hasErrors() method
