Method Summary

Modifier and Type	Method	Description
java.lang.Class<KeyDeriver>	getInputPrimitiveClass()	Returns the primitive class object of the primitive used to create B.
java.lang.Class<KeysetDeriver>	getPrimitiveClass()	Returns the primitive class object of the primitive managed.
static void	register()	Registers this wrapper with Tink, allowing to use the primitive.

Method Detail

wrap

public KeysetDeriver wrap(KeysetHandleInterface keysetHandle,
                          MonitoringAnnotations annotations,
                          PrimitiveWrapper.PrimitiveFactory<KeyDeriver> factory)
                   throws java.security.GeneralSecurityException

Description copied from interface: PrimitiveWrapper

Wraps a PrimitiveSet and returns a single instance.

This method gets called when a new primitive is created.

Specified by:

wrap in interface PrimitiveWrapper<KeyDeriver,KeysetDeriver>

Throws:

java.security.GeneralSecurityException

getPrimitiveClass

public java.lang.Class<KeysetDeriver> 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<KeyDeriver,KeysetDeriver>

getInputPrimitiveClass

public java.lang.Class<KeyDeriver> 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<KeyDeriver,KeysetDeriver>

register

public static void register()
                     throws java.security.GeneralSecurityException

Registers this wrapper with Tink, allowing to use the primitive.

Throws:

java.security.GeneralSecurityException

registerToInternalPrimitiveRegistry

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

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

Throws:

java.security.GeneralSecurityException
