getPrimitive

public abstract <P> P getPrimitive(Key key,
                                   Class<P> primitiveClass)
                            throws GeneralSecurityException

Given a key and a desired primitive class, creates the required primitive.

Throws:

GeneralSecurityException

wrap

public abstract <B,P> P wrap(PrimitiveSet<B> primitiveSet,
                             Class<P> clazz)
                      throws GeneralSecurityException

Wraps the primitives in the primitive set into the provided class.

Throws:

GeneralSecurityException - if the wrapper for the provided pair (input class, wrapped class) is not registered

getInputPrimitiveClass

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

Given the target class, reveals primitive set of what type should be provided to the InternalConfiguration.wrap method in order to get a wrapped object of the target class.

Throws:

GeneralSecurityException
