Constructor Summary

HighLowKeyGeneratorFactory()

Method Summary

KeyGenerator	createKeyGenerator() Create a default key generator instance with the algorithm the factory is responsible for.
KeyGenerator	createKeyGenerator(KeyGeneratorDef definition) Create a key generator instance from the given definition with the algorithm the factory is responsible for.
String	getAlgorithmName() Get name of key generator algorithm.
boolean	hasMandatoryParameters() Does the algorithm has mandatory parameters and therefore requires a key generator definition in mapping file?

Constructor Detail

HighLowKeyGeneratorFactory

public HighLowKeyGeneratorFactory()

Method Detail

getAlgorithmName

public String getAlgorithmName()

Get name of key generator algorithm.

Specified by:

getAlgorithmName in interface KeyGeneratorFactory

Returns:

Name of key generator algorithm.

hasMandatoryParameters

public boolean hasMandatoryParameters()

Does the algorithm has mandatory parameters and therefore requires a key generator definition in mapping file?

Specified by:

hasMandatoryParameters in interface KeyGeneratorFactory

Returns:

true if algorithm has mandatory parameters and therefore requires a key generator definition in mapping file. false if algorithm does not require parameters or has only optional parameters.

createKeyGenerator

public KeyGenerator createKeyGenerator()
                                throws GeneratorException

Create a default key generator instance with the algorithm the factory is responsible for. This is only possible for those algorithms that do not require mandatory parameters.

Specified by:

createKeyGenerator in interface KeyGeneratorFactory

Returns:

A default key generator instance with the algorithm the factory is responsible for.

Throws:

GeneratorException - If creation of default key generator is not possible due to required mandatory parameters.

createKeyGenerator

public KeyGenerator createKeyGenerator(KeyGeneratorDef definition)
                                throws GeneratorException

Create a key generator instance from the given definition with the algorithm the factory is responsible for.

Specified by:

createKeyGenerator in interface KeyGeneratorFactory

Parameters:

definition - The definition to initialize the key generator.

Returns:

A key generator instance initialized with given definition with the algorithm the factory is responsible for.

Throws:

GeneratorException - If failed to create a key generator instance.
