next

public static UUID next()

Constructs a time-based UUID.V1 UUID using the default Node and Timestamp.monotonic() as the monotonic timestamp supplier.

Returns:

a UUID.V1 UUID

next

public static UUID next(Node node)

Constructs a time-based UUID.V1 UUID using the provided Node and Timestamp.monotonic() as the monotonic timestamp supplier.

Parameters:

node - Node for the V1 UUID generation

Returns:

a UUID.V1 UUID

next

public static UUID next(Node node,
                        java.util.function.LongSupplier monotonicSupplier)

Constructs a time-based UUID.V1 UUID using the provided Node and monotonic timestamp supplier.

Parameters:

node - node for the V1 UUID generation

monotonicSupplier - monotonic timestamp which assures the V1 UUID time is unique

Returns:

a UUID.V1 UUID
