Interface LicenseValidator

All Known Implementing Classes:

DefaultLicenseValidator

public interface LicenseValidator

Specifies an interface for validating licenses. Users of License Manager do not have to implement this interface. If it is not implemented, it is assumed that all licenses are valid. Users are encouraged, however, to implement interface.

There is a default implementation, DefaultLicenseValidator, that ensures the current date is between the license's good-after and good-before dates (the license has taken effect and hasn't expired).
