Java – on COM sun. Using generics in codemodel

Use COM sun. Codemodel, I want to generate a generic LinkedList field I can create an original field using the following code:

JDefinedClass masterClass;
String detailName;
JDefinedClass detailClass;
JFieldVar detailField = masterClass.field(JMod.PRIVATE,LinkedList.class,detailName);

But I can't find a method to create a LinkedList using the generic type detailclass

Solution

JClass detailClass = codeModel.ref(String.class);

JClass detailClass = codeModel.ref(String.class);
String detailName = "myLinkedListField";
JClass rawLLclazz = codeModel.ref(LinkedList.class);
JClass fieldClazz = rawLLclazz.narrow(detailClass);
JFieldVar detailField = def.field(JMod.PRIVATE,fieldClazz,detailName);
