This class implements a value‐semantic Guid type.
Synopsis
Declared in <bdlb_guid.h>
class Guid;Description
Each object represents an unconstrained Guid object, but its uniqueness is not guaranteed, and this component provides no ability to generate a GUID.
This class provides a constructor and several accessors with names and parameters phrased using RFC 4122 field names. These names are used (by RFC 4122 and this component) as designators for parts of the GUID even when those names do not accurately describe the parts (for example, time low names bytes 0‐3 of the GUID regardless of whether the values of those bytes come from a clock or are generated randomly).
