public MutableList<T> asSynchronized()
MutableCollection
It is imperative that the user manually synchronize on the returned collection when iterating over it using the standard JDK iterator or JDK 5 for loop.
MutableCollection collection = myCollection.asSynchronized(); ... synchronized(collection) { Iterator i = c.iterator(); // Must be in the synchronized block while (i.hasNext()) foo(i.next()); }Failure to follow this advice may result in non-deterministic behavior.
The preferred way of iterating over a synchronized collection is to use the collection.forEach() method which is properly synchronized internally.
MutableCollection collection = myCollection.asSynchronized(); ... collection.forEach(new Procedure() { public void value(Object each) { ... } });
The returned collection does not pass the hashCode and equals operations through to the backing collection, but relies on Object's equals and hashCode methods. This is necessary to preserve the contracts of these operations in the case that the backing collection is a set or a list.
The returned collection will be serializable if this collection is serializable.
