protected abstract void engineInit(ManagerFactoryParameters spec) throws InvalidAlgorithmParameterException
In some cases, initialization parameters other than a keystore
and password may be needed by a provider. Users of that
particular provider are expected to pass an implementation of
the appropriate ManagerFactoryParameters
as
defined by the provider. The provider can then call the
specified methods in the ManagerFactoryParameters
implementation to obtain the needed information.
