public interface MACCalculatorFactory

Factory creating instances of MACCalculator.

Implementations of this interface are used by CryptoRegistry.createMACCalculator(String, boolean) to provide instances of MACCalculator.

Note: Implementors should subclass AbstractMACCalculatorFactory instead of directly implementing this interface.

Method Summary

MACCalculator	createMACCalculator(boolean initWithDefaults) Create a new instance of MACCalculator and optionally initialise it.
String	getAlgorithmName() Get the name of the MAC algorithm implemented by the MACCalculator created by this factory.
void	setAlgorithmName(String algorithmName) Set the name of the MAC algorithm.

Method Detail

createMACCalculator

MACCalculator createMACCalculator(boolean initWithDefaults)

Create a new instance of MACCalculator and optionally initialise it.

Parameters:

initWithDefaults - whether to initialise the MACCalculator with default values so that it can be used immediately as-is.

Returns:

a new instance of MACCalculator (iff initWithDefaults==true ready-to-use; otherwise requiring initialisation before it can be used).

getAlgorithmName

String getAlgorithmName()

Get the name of the MAC algorithm implemented by the MACCalculator created by this factory. See Supported algorithms for a list of supported algorithms.

Returns:

the name of the MAC algorithm.

setAlgorithmName

void setAlgorithmName(String algorithmName)

Set the name of the MAC algorithm. This method is called once and should throw an IllegalStateException if it is called again.

Parameters:

algorithmName - the name of the MAC algorithm; never null.
