Interface PrimitiveWrapper<P>

All Known Implementing Classes:

public interface PrimitiveWrapper<P>

Basic interface for wrapping a primitive.

A PrimitiveSet can be wrapped by a single primitive in order to fulfil a cryptographic task. This is done by the PrimitiveWrapper. Whenever a new primitive type is added to Tink, the user should define a new PrimitiveWrapper and register it by calling com.google.crypto.tink.Registry#registerPrimitiveWrapper.

Method Summary

Modifier and Type	Method and Description

P	wrap(PrimitiveSet<P> set) Wraps a PrimitiveSet and returns a single instance.

Method Detail

P wrap(PrimitiveSet<P> set)
throws GeneralSecurityException

Wraps a PrimitiveSet and returns a single instance. This has to be implemented when a new primitive type is added.

Throws:

GeneralSecurityException

getPrimitiveClass

Class<P> getPrimitiveClass()

Returns the primitive class object of the primitive managed. Used for internal management. Should be implemented as return P.class; when implementing a key manager for primitive {$code P}.
