EspressoOptional

Kotlin |Java

public final class EspressoOptional<T>

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

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