Constructor Detail

HighLowKeyGeneratorFactory

public HighLowKeyGeneratorFactory()
Method Detail

getAlgorithmName

public java.lang.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.
