EspressoOptional

Kotlin |Java

public final class EspressoOptional

This class is a reimplementation of com.google.common.base.Optional to maintain API compatibility with older versions of espresso.

Parameters
	the type of instance that can be contained. `Optional` is naturally covariant on this type, so it is safe to cast an `Optional` to `Optional` ~~for any supertype `S` of `T`.~~
