Eric Milles updated GROOVY-9813:
--------------------------------
Description:
Java supports each of the following functional interface assignments for a
variadic method like {{java.util.Arrays#asList}}.
{code:groovy}
import java.util.function.*
@groovy.transform.CompileStatic
void test() {
Supplier<List> zero = Arrays::asList
Function<Integer, List> one = Arrays::asList
BiFunction<Integer, Integer, List> two = Arrays::asList
}
{code}
Note: Groovy compiler only produces error for first incompatible method
reference.
was:
Java supports each of the following functional interface assignments for a
variadic method like {{java.util.Arrays#asList}}. Groovy 3 does not yet
implement the first case.
{code:groovy}
import java.util.function.*
@groovy.transform.CompileStatic
void test() {
Supplier<List> zero = Arrays::asList
Function<Integer, List> one = Arrays::asList
BiFunction<Integer, Integer, List> two = Arrays::asList
}
{code}
> Improve support for matching functional interface to variadic method reference
