Interface ContentDependentAttribute

All Known Implementing Classes:

FingerprintAttribute, MessageIntegrityAttribute

public interface ContentDependentAttribute

ContentDependentAttributes have a value that depend on the content of the message. The MessageIntegrityAttribute and FingerprintAttribute are two such attributes.

Rather than encoding them via the standard Attribute.encode() method, the stack would use the one from this interface.
