public class JavaTypeJoiner extends BinaryCommunicativeJavaTypeVisitor<JavaType>
A service that can compute the least common supertype of two given Java types. Examples: given three classes A, B, C with B <: A. visitTypes(A, B) -> A visitTypes(A, C) -> Object visitTypes(B, B) -> B visitTypes(List, List) -> List<? extends A> visitTypes(List, List) -> List<?> visitTypes(List, B) -> Object visitTypes(boolean, Boolean) -> Boolean visitTypes(int, float) -> float visitTypes(Integer, BigDecimal) -> Number visitTypes(List, List<? extends BigDecimal>) -> List<? extends Number> Based on the subtype relation of the Java specification: https://docs.oracle.com/javase/specs/jls/se11/html/jls-4.html#jls-4.10
