Class Method Details

.load!(dir = nil) ⇒ Array<Class>

Registers templates for every view in the manifest. Idempotent: previously generated view classes are evicted first, so rebuilt manifests (new hashes) load cleanly on app reload.

Returns:

  • (Array<Class>) —

    the generated ResourceTemplate subclasses
