Detailed Description

This component implements a simple value-semantic type, bmqt::Version representing the version of an object. It is used in particular to attach a version attribute to a bmqa::Message, so that a consuming application receiving a message knows the version of the schema that was used for publishing.

A version is represented by two numbers: a major and a minor version. Both are positive integers within the range [0-255].

Usage Example

bmqt::Version version(1, 3);
BSLS_ASSERT(version.major() == 1);
BSLS_ASSERT(version.minor() == 3);
version.setMajor(2).setMinor(4);
BSLS_ASSERT(version.major() == 2);
BSLS_ASSERT(version.minor() == 4);
