IdempotentSecureHashReceiver
ensures that only unique messages are
received by a component. It does this by calculating the SHA-256 hash of the
message itself. This provides a value with an infinitesimally small chance of a
collision. This can be used to filter message duplicates. Please keep in mind that
the hash is calculated over the entire byte array representing the message, so any
leading or trailing spaces or extraneous bytes (like padding) can produce
different hash values for the same semantic message content. Care should be taken
to ensure that messages do not contain extraneous bytes. This class is useful when
the message does not support unique identifiers. This implementation provides for
a persistent store of message hash values via the underlying file system and is
suitable in failover environments.
