-----------------------------------------
Summary: Import on code paste error
Key: NETBEANS-1937
URL: https://issues.apache.org/jira/browse/NETBEANS-1937
Project: NetBeans
Issue Type: Bug
Components: java - Source
Affects Versions: 10.0
Environment: Mac
JDK 10
Reporter: Austin Stephens
Create a class file named "IterableUtil.java" and paste the following into the
class:
{code:java}
@Deprecated
public static <T> Iterable<T> cast(final Iterable<?> source){
return () -> new Iterator<T>() {
final Iterator<?> iterator = source.iterator();
@Override
public boolean hasNext() {
return iterator.hasNext();
}
@Override
@SuppressWarnings("unchecked")
public T next() {
return (T)iterator.next();
}
@Override
public void remove() {
iterator.remove();
}
};
}
public static <T,E> ListIterator<T> cast(final ListIterator<E> source,
final Class<E> clazz){
return new ListIterator<T>() {
@Override
public boolean hasNext() {
return source.hasNext();
}
@Override
@SuppressWarnings("unchecked")
public T next() {
return (T)source.next();
}
@Override
public boolean hasPrevious() {
return source.hasPrevious();
}
@Override
@SuppressWarnings("unchecked")
public T previous() {
return (T)source.previous();
}
@Override
public int nextIndex() {
return source.nextIndex();
}
@Override
public int previousIndex() {
return source.nextIndex();
}
@Override
public void remove() {
source.remove();
}
@Override
public void set(T e) {
source.set(clazz.cast(e));
}
@Override
public void add(T e) {
source.add(clazz.cast(e));
}
};
}
/**
*
* @param <T>
* @param collection
* @return
* @deprecated Does not truly do the conversion.
*/
@Deprecated
public static <T> Iterable<T> enumerationToIterable(final Enumeration<T>
collection){
return () -> enumerationToIterator(collection);
}
public static <T> Iterator<T> enumerationToIterator(
final Enumeration<T> collection) {
return new Iterator<T>() {
@Override
public boolean hasNext() {
return collection.hasMoreElements();
}
@Override
public T next() {
return collection.nextElement();
}
@Override
public void remove() {
throw new UnsupportedOperationException("Not supported."); //To
change body of generated methods, choose Tools | Templates.
}
};
}
{code}
The IDE will ask if you would like it to resolve imports. Click "ok". The
resulting code will now have `return new IteratorIterator<T>(){` and `return
new ListIteratorListIterator<T>() {`, which is wrong.
