bool

Give a version object its boolean truth value - true unless every component is zero.

תקציר

if ($v) { ... }

This backs the overloaded bool operator. A version is false only when it has no non-zero component, i.e. it compares equal to v0.0.0. Every other version is true, including v0.0.1.

מה מוחזר

A boolean: 1 for any non-zero version, the empty string for v0 / 0.000 / v0.0.0.
