of a generator method invocation (Section 16.2.2, “Generator Method Invocations”).

The type of the expression must be assignable to the declared return type
of the generator method declaration, or a compile-time error occurs.
The execution of a yield
statement with
expression e
is equivalent
to the sequential evaluation of the method invocation expression
c
.consume(
e
)
,
where c
is the implicit consumer parameter
of the generator method declaration (Section 11.2.1, “Generator Method Declarations”)
and the results of the invocation are discarded.
