Examples of io.apigee.trireme.core.NodeVersion

io.apigee.trireme.core.NodeVersion
This class is used when comparing versions of Node.js. It implements many of the facilities of "semver" without necessarily getting carried away. Basically, a version has three digits -- major, minor, and release. A version may be expressed as the string "1.2.3". Versions may also have wildcards, such as "1.2.x", "1.x.x", "x.x.x", or just "x". A NodeVersion has an attachment so that you can use it to match an actual implementation of something.
