  org.cumulus4j.crypto.AbstractMACCalculatorFactory

All Implemented Interfaces:

MACCalculatorFactory

Direct Known Subclasses:

MACCalculatorFactoryImpl

public abstract class AbstractMACCalculatorFactory
extends Object
implements MACCalculatorFactory

Abstract base class for implementing a MACCalculatorFactory.

Implementors should subclass this class instead of directly implementing the interface MACCalculatorFactory.

Constructor Detail

AbstractMACCalculatorFactory

public AbstractMACCalculatorFactory()

Method Detail

getAlgorithmName

public String getAlgorithmName()

Description copied from interface: MACCalculatorFactory

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

Specified by:

getAlgorithmName in interface MACCalculatorFactory

Returns:

the name of the MAC algorithm.

setAlgorithmName

public void setAlgorithmName(String algorithmName)

Description copied from interface: MACCalculatorFactory

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

Specified by:

setAlgorithmName in interface MACCalculatorFactory

Parameters:

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

See Also:

MACCalculatorFactory.getAlgorithmName()

createMACCalculator

public MACCalculator createMACCalculator(boolean initWithDefaults)

Description copied from interface: MACCalculatorFactory

Create a new instance of MACCalculator and optionally initialise it.

Specified by:

createMACCalculator in interface MACCalculatorFactory

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).

_createMACCalculator

protected abstract MACCalculator _createMACCalculator()
