WellBehavedMap

java.lang.Object
- com.google.common.collect.ForwardingObject
- - com.google.common.collect.ForwardingMap<K,V>
  - - com.google.common.collect.WellBehavedMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>
```
@GwtCompatible
final class WellBehavedMap<K,V>
extends ForwardingMap<K,V>
```
Workaround for EnumMap bug. If you want to pass an EnumMap, with the intention of using its entrySet() method, you should wrap the EnumMap in this class instead.
This class is not thread-safe even if the underlying map is.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected java.util.Map<K,V>`	`delegate()`	Returns the backing delegate instance that methods are forwarded to.
`java.util.Set<java.util.Map.Entry<K,V>>`	`entrySet()`
`(package private) static <K,V> WellBehavedMap<K,V>`	`wrap(java.util.Map<K,V> delegate)`	Wraps the given map into a `WellBehavedEntriesMap`, which intercepts its `entrySet()` method by taking the `Set<K> keySet()` and transforming it to `Set<Entry<K, V>>`.

    Description copied from class: ForwardingObject
    
    Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
