Dear all,
I'mv trying to use the new `macro` feature to execute a class method call
expression using an executor service.
I've tried:
private BlockStatement wrap(MethodCallExpression mce) {
return macro(true,{
def executor =
java.util.concurrent.Executors.newCachedThreadPool()
def list = new ArrayList(1)
list.add( { return $v{ mce } } as Callable )
def result = executor.invokeAll(list)
return result.get(0).get()
})
}
and
private BlockStatement wrap(MethodCallExpression mce) {
return macro(true,{
def task = new java.util.concurrent.Callable<Object>() {
@Override
Object call() throws Exception { return $v{ mce } }
}
ExecutorService executor =
java.util.concurrent.Executors.newCachedThreadPool()
def list = new ArrayList(1)
list.add(task)
def result = executor.invokeAll(list)
return result.get(0).get()
})
}
However none of them work. The first return a NPE during compilation and
the second reports:
Groovyc: [Static type checking] - Cannot find matching method
nextflow.ast.ProxyImpl$1#$v(groovy.lang.Closure). Please check if the
declared type is correct and if the method exists.
(using CompileDynamic I got a NPE error one more time)
What I'm missing? is it possible to handle this use case with an ast macro ?
p
