public boolean isAssignableFrom(TypeInformation<?> target)
TypeInformation
TypeInformation
can be safely assigned to the given one. Mimics semantics of
Class.isAssignableFrom(Class)
but takes generics into account. Thus it will allow to detect that a
List<Long>
is assignable to List<? extends Number>
.
