Informations about the package optional

Optional (like in Java Platform SE 8 but in PHP)

A container object which may or may not contain a non-null value. If a value is present, isPresent() will return true and get() will return the value.

Additional methods that depend on the presence or absence of a contained value are provided, such as orElse() (return a default value if value not present) and ifPresent() (execute a block of code if the value is present).

This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of Optional may have unpredictable results and should be avoided.

-- Optional (Java Platform SE 8)

It is an easy way to make sure that everyone has to check if they have (not) received a null.
