Class PrfSetWrapper

java.lang.Object

com.google.crypto.tink.prf.PrfSetWrapper

All Implemented Interfaces:

PrimitiveWrapper<Prf,PrfSet>

@Immutable
public class PrfSetWrapper
extends Object
implements PrimitiveWrapper<Prf,PrfSet>

PrfSetWrapper is the implementation of PrimitiveWrapper for the PrfSet primitive.

The returned primitive has instances of Prf for each key in the KeySet. The individual Prf instances can then be used to compute psuedo-random sequences from the underlying key.

Method Detail

wrap

public PrfSet wrap(PrimitiveSet<Prf> set)
            throws GeneralSecurityException

Description copied from interface: PrimitiveWrapper

Wraps a PrimitiveSet and returns a single instance.

This method gets called when a new primitive is created. primitiveSet is immutable. This has to be implemented when a new primitive type is added.

Specified by:

wrap in interface PrimitiveWrapper<Prf,PrfSet>

Throws:

GeneralSecurityException

getPrimitiveClass

public Class<PrfSet> getPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive managed. Used for internal management. Should be implemented as return P.class; when implementing a wrapper creating objects of type P.

Specified by:

getPrimitiveClass in interface PrimitiveWrapper<Prf,PrfSet>

getInputPrimitiveClass

public Class<Prf> getInputPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive used to create B. Used for internal management. Should be implemented as return B.class;.

Specified by:

getInputPrimitiveClass in interface PrimitiveWrapper<Prf,PrfSet>

register

public static void register()
                     throws GeneralSecurityException

Throws:

GeneralSecurityException

registerToInternalPrimitiveRegistry

public static void registerToInternalPrimitiveRegistry(PrimitiveRegistry.Builder primitiveRegistryBuilder)
                                                throws GeneralSecurityException

registerToInternalPrimitiveRegistry is a non-public method (it takes an argument of an internal-only type) registering an instance of PrfSetWrapper to the provided PrimitiveRegistry.Builder.

Throws:

GeneralSecurityException
