Suppose I have:
class Blah<T> { void doit(Closure<R> c) }
Used so:
Blah<String> b = new Blah<>("abc")
b.doit {it.trim()}
Is there a ClosureSignatureHint that specifies this?
This method from DGM is what I'd want, except doit is an instance method and
not a static one, so I can't use "FirstParam"
public static <T> Collection<T> each(Collection<T> self,
@ClosureParams(FirstParam.FirstGenericType.class) Closure closure)
I even tried FromString, but type checker still thinks the closure takes object.
void doit(@ClosureParams(value=FromString.class, options=["T"]) Closure<?> c)
[Static type checking] - Cannot find matching method java.lang.Object#trim().
Please check if the declared type is right and if the method exists.
I even tried my own hint class:
public class GenericClassType extends SingleSignatureClosureHint {
public ClassNode[] getParameterTypes(MethodNode node, String[] options,
SourceUnit sourceUnit, CompilationUnit unit, ASTNode usage) {
return new ClassNode[] { pickGenericType(node.getDeclaringClass(), 0) };
}
}
In GenericClassType hint it finds "T -> java.lang.Object". It doesn't seem to
know about the Blah instance.
What's weird is even if I change doit to take a java.util.function.Consumer<T>,
it still doesn't work.
