Class AbstractValidator<T>

java.lang.Object
  org.srplib.validation.AbstractValidator<T>

All Implemented Interfaces:

Validator<T>

public abstract class AbstractValidator<T>
extends Object
implements Validator<T>

Base abstract class for validators implementations.

This base class simplifies validators creation because subclasses are responsible only for checking validity condition and providing validation error. This class populates validatable with validation error (if any)

TODO: does this class make sense? Subclasses have no chance to add value validation error.
