Detailed Description

This is a lightweight class for generating unique identifiers.

Note that the numbers generated are not globally unique. Two UIDGenerators may return the same IDs.

The counter is an implementation-defined maximum width integer. This is typically 64 bits, yielding a max value of 18446744073709551615. If more identifiers are needed, multiple UIDGenerators could be used together.

UIDGenerators are noncopyable.
