Here's what it looks like:
private <T extends CommonUpdatableEntity> Store<T, Query<T>>
getStoreInstance(final Class<T> entity) {
ParameterizedType parameterizedStoreType = new ParameterizedType()
{
public Type[] getActualTypeArguments() {
return new Class[] { entity.getClass() , Query.class};
}
public Type getOwnerType() {
return null;
}
public Type getRawType() {
return Store.class;
}
};
ParameterizedType parameterizedQueryType = new ParameterizedType()
{
public Type[] getActualTypeArguments() {
return new Class[] { entity.getClass() };
}
public Type getOwnerType() {
return null;
}
public Type getRawType() {
return Query.class;
}
};
// TODO:
return null;
}
