verifyExtends static method

void verifyExtends(
  1. TaskPlatform instance
)

Throws an AssertionError if instance does not extend TaskPlatform.

This is used by the app-facing Task to ensure that the object in which it's going to delegate calls has been constructed properly.

Implementation

static void verifyExtends(TaskPlatform instance) {
  PlatformInterface.verifyToken(instance, _token);
}
