Interface FingerprintProvider

All Known Implementing Classes:

Md5FingerprintProvider, UuidFingerprintProvider

public interface FingerprintProvider

Provides a fingerprint for given HttpError.

A fingerprint helps with identifying errors across domains. With fingerprint you can easily correlate error reported in application (e.g. as entry in application log) with user-friendly error reported via HTTP (which doesn't - and shouldn't - contain vital information, like e.g. stacktrace).
