Paul King updated GROOVY-9606:
------------------------------
Description:
{code:groovy}
trait SomeGroovyTrait<D> {
List<D> list(D arg) {
[arg]
}
}
class SomeGroovyClass implements SomeGroovyTrait<String> { }
{code}
Generates a stub like this
{code:groovy}
...
public class SomeGroovyClass implements SomeGroovyTrait<java.lang.String>,
groovy.lang.GroovyObject {
...
public java.util.List<D> list(D arg) { return (java.util.List<D>)null;}
// <== D should be String
}
{code}
Note that {{value}} has type {{V}} instead of type {{String}} and the generic
reference isn't declared in the class either.
was:
{code:groovy}
trait Test<V> {
V value
}
class TestImpl implements Test<String> { }
{code}
Generates a stub like this
{code:groovy}
import java.lang.*;
import java.io.*;
import java.net.*;
import java.util.*;
import groovy.lang.*;
import groovy.util.*;
public class TestImpl
extends java.lang.Object implements
Test<java.lang.String>, groovy.lang.GroovyObject {
;
@groovy.transform.Generated() @groovy.transform.Internal() public
groovy.lang.MetaClass getMetaClass() { return (groovy.lang.MetaClass)null;}
@groovy.transform.Generated() @groovy.transform.Internal() public void
setMetaClass(groovy.lang.MetaClass mc) { }
@groovy.transform.Generated() @groovy.transform.Internal() public
java.lang.Object invokeMethod(java.lang.String method, java.lang.Object
arguments) { return null;}
@groovy.transform.Generated() @groovy.transform.Internal() public
java.lang.Object getProperty(java.lang.String property) { return null;}
@groovy.transform.Generated() @groovy.transform.Internal() public void
setProperty(java.lang.String property, java.lang.Object value) { }
public V getValue() { return null;}
public void setValue(V value) { }
}
{code}
Note that {{value}} has type {{V}} instead of type {{String}} and the generic
reference isn't declared in the class either.
