  +--org.arch4j.persistence.domainmapper.JugRandomBasedUuidGenerator

All Implemented Interfaces:

IdentifierGenerator

public class JugRandomBasedUuidGenerator

extends Object

implements IdentifierGenerator

This class implements the IdentifierGenerator interface to provide a random-based UUID generator. The actual implementation is delegated to a third-party library, the open-source Java UUID Generator (JUG). The returned UUID string is 36 characters long; for example, c383402e-98a8-4535-8b80-3a0216d78f80

Subclasses are free to extend this class and override the method getSecureRandomNumberGenerator(), which provides a SecureRandom number generator for the JUG implementation.

public Serializable generate()

Generate a new unique identifier.

Specified by:

generate in interface IdentifierGenerator

Returns:

A Serializable unique identifier.

getSecureRandomNumberGenerator

protected SecureRandom getSecureRandomNumberGenerator()

Returns a SecureRandom number generator that is used to seed the JUG implementation. This method can be overridden in subclasses to provide their own number generator. Defaults to the number generator JUG uses.

Returns:

A SecureRandom, cryptographically strong pseudo-random number generator (PRNG).
