+Swift Package Manager + +```swift +dependencies: [ + .package( + url: "https://github.com/tidal-music/network-time.git", + .upToNextMajor(from: "$VERSION") + ) +] +``` + +If you plan to use this tool from Objective-C, all public API symbols are prefixed with TNT (for +TidalNetworkTime) to avoid naming conflicts. + +
+ +Version numbers can be found under [Releases](https://github.com/tidal-music/network-time/releases). + +## Usage + +Create your `SNTPClient` via its constructor. Its API allows you to toggle synchronization (starts +off) and to retrieve the time based on the latest successful synchronization, if any. + +The property that retrieves the aforementioned time is nullable as it will return `null` if no +synchronization has occurred successfully during the lifetime of the process and no backup file has +been specified for the `SNTPClient` instance or said file contains no valid prior synchronization +data. + +## networktime-singletons + +This is a tiny utility on top of the base artifact that extends the `SNTPClient` API by adding a new +property, `SNTPClient.singleton`, which allows you to pin `SNTPClient` instances into memory, keyed +uniquely by their constructor parameters (ordering of elements in collection-like parameters is +ignored). Invoking the property on an `SNTPClient` whose parameters result in a key not +corresponding to an already pinned instance will associate the key to said instance, pin it into +memory and return the receiver, and invoking it on an `SNTPClient` whose parameters result in a key +of an already-pinned association will return the pinned instance, allowing for the original receiver +to be freely garbage-collected when applicable. `SNTPClient.singleton` is thread-safe. + +While using the core artifact instead is strongly recommended whenever possible, this one may be +useful if your codebase requires exactly the same clock reference using exactly the same +synchronization pacing across multiple places but it does not feature integration points between +these that allow you to share a single `SNTPClient` instance. diff --git a/build.gradle.kts b/build.gradle.kts new file mode 100644 index 00000000..16415733 --- /dev/null +++ b/build.gradle.kts @@ -0,0 +1,10 @@ +plugins { +
