Interface BindBeforeValidation

public interface BindBeforeValidation

Indicates a domain object wishes to perform additional binding before the Validator is called.

Typically this type of binding sets up private or protected properties that the end user is not responsible for modifying. Whilst generally this can be done by adding a hook to every property setter, the BindBeforeValidation interface provides an AOP-style approach that ensures missing hooks do not cause invalid object state.

Method Summary

void	bindSupport() This method will be called by infrastructure code before attempting to validate the object.

Method Detail

bindSupport

void bindSupport()
                 throws BindException

This method will be called by infrastructure code before attempting to validate the object. Given this method is called prior to validation, implementations of this method should not assume the object is in a valid state.

Implementations should modify the object as required so that the Validator will succeed if user-controllable properties are correct.

Throws:

BindException - if there are problems that the method wish to advise (note that the Validator should be allowed to determine errors in most cases, rather than this method doing so)
