Constructor Detail

SecureRandomIdentifierGenerationStrategy

public SecureRandomIdentifierGenerationStrategy()

Constructor. Initializes the random number source to a new SecureRandom, size of identifier is set to 16 bytes, and the encoder is set to a Hex.

SecureRandomIdentifierGenerationStrategy

public SecureRandomIdentifierGenerationStrategy(@ParameterName(name="identifierSize")
                                                int identifierSize)

Constructor. Initializes the random number source to a new SecureRandom and the encoder is set to a Hex.

Parameters:

identifierSize - number of random bytes in identifier

SecureRandomIdentifierGenerationStrategy

public SecureRandomIdentifierGenerationStrategy(@ParameterName(name="source") @Nonnull
                                                SecureRandom source,
                                                @ParameterName(name="identifierSize")

                                                org.apache.commons.codec.BinaryEncoder identifierEncoder)

Constructor.

Parameters:

source - source of random bytes

identifierSize - number of random bytes in the identifier

identifierEncoder - encoder used to convert random bytes to string identifier
