SerializableComparatorWrapperClass

java.lang.Object
- org.danekja.java.misc.serializable.SerializableComparatorWrapperClass<T>

Type Parameters:

T - comparable type

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator<T>, SerializableComparator<T>
```
public class SerializableComparatorWrapperClass<T>
extends java.lang.Object
implements SerializableComparator<T>
```
Wrapper for a non-serializable subclass of Comparator, such as Collator. This way you can still use such comparators in a serializable way. This wrapper calls the given SerializableSupplier to retrieve a delegate Comparator which it uses for all calls to its compare(Object, Object)-method. It caches the retrieved Comparator in a transient field for efficiency. Usage example:
```
 SerializableComparator<Object> collator = new SerializableComparatorWrapper<>(() -> Collator.getInstance(Locale.UK));
 SerializableComparator<Object> objectComparator = SerializableComparator.comparing(Object::toString, collator);
 
```
(Note that Collator is an instance of Comparator typed with Object, not with a generic type variable.)
