Examples with VersionRange org.eclipse.n4js.semver.Semver.VersionRange used on opensource projects

Example 1 with VersionRange

use of org.eclipse.n4js.semver.Semver.VersionRange in project n4js by eclipse.

the class SemverMatcher method isWildcard.

/**
 * The matching of wildcards is specified different on <a href="https://docs.npmjs.com/misc/semver">npmjs.com<a>
 * than it is behaving using npm with regard to the handling of pre-release tagged versions. Namely, npmjs.com says
 * {@code "" (empty string) := * := >=0.0.0} which is not true for npm. Therefore, this matching method will mimic
 * the npm behavior e.g. when executing 'npm install package@*' and match any version for {@code @*} including
 * pre-release tagged ones.
 *
 * @return true iff the given constraint consists of one wildcard only

Example 2 with VersionRange
