Class MutablePrimitiveRegistry

java.lang.Object

com.google.crypto.tink.internal.MutablePrimitiveRegistry

public final class MutablePrimitiveRegistry
extends Object

A Mutable version of the PrimitiveRegistry.

This class probably shouldn't exist; it would be better if we had only the PrimitiveRegistry. However, at the moment, we need this, since a call to e.g.

 AesCmacKeyManager.register() 

should register such an object into a global, mutable registry.

Method Detail

globalInstance

public static MutablePrimitiveRegistry globalInstance()

resetGlobalInstanceTestOnly

public static void resetGlobalInstanceTestOnly()

registerPrimitiveConstructor

public <KeyT extends Key,PrimitiveT> void registerPrimitiveConstructor(PrimitiveConstructor<KeyT,PrimitiveT> constructor)
                                                                throws GeneralSecurityException

Registers a key primitive constructor for later use in getPrimitive(KeyT, java.lang.Class<PrimitiveT>).

This registers a primitive constructor which can later be used to create a primitive by calling getPrimitive(KeyT, java.lang.Class<PrimitiveT>). If a constructor for the pair (KeyT, PrimitiveT) has already been registered and is the same, then the call is ignored; otherwise, an exception is thrown.

Throws:

GeneralSecurityException

registerPrimitiveWrapper

public <InputPrimitiveT,WrapperPrimitiveT> void registerPrimitiveWrapper(PrimitiveWrapper<InputPrimitiveT,WrapperPrimitiveT> wrapper)
                                                                  throws GeneralSecurityException

Throws:

GeneralSecurityException

getPrimitive

public <KeyT extends Key,PrimitiveT> PrimitiveT getPrimitive(KeyT key,
                                                             Class<PrimitiveT> primitiveClass)
                                                      throws GeneralSecurityException

Creates a primitive from a given key.

This will look up a previously registered constructor for the given pair of (KeyT, PrimitiveT), and, if successful, use the registered PrimitiveConstructor object to create the requested primitive. Throws if the required constructor has not been registered, or if the primitive construction threw.

Throws:

GeneralSecurityException

getInputPrimitiveClass

public <WrapperPrimitiveT> Class<?> getInputPrimitiveClass(Class<WrapperPrimitiveT> wrapperClassObject)
                                                    throws GeneralSecurityException

Throws:

GeneralSecurityException

wrap

public <InputPrimitiveT,WrapperPrimitiveT> WrapperPrimitiveT wrap(PrimitiveSet<InputPrimitiveT> primitives,
                                                                  Class<WrapperPrimitiveT> wrapperClassObject)
                                                           throws GeneralSecurityException

Throws:
