Class ValdiRuntime

valdi/src/java/com/snap/valdi/ValdiRuntime.kt:49–364

* The Runtime is one of the core class of Valdi. It is primarily used to create a * View tree for its document name. Because it is backed by a C++ instance, destroy() * should be called when the Runtime is not needed to release the native resources. * The Runtime is stateful and holds a cache. Because of this, you should typically only * have a single instance per app. This is especially true

 * enabled at all time.
