Class SerializedLambda
- All Implemented Interfaces:
- Serializable
Implementors of serializable lambdas, such as compilers or language
 runtime libraries, are expected to ensure that instances deserialize properly.
 One means to do so is to ensure that the writeReplace method returns
 an instance of SerializedLambda, rather than allowing default
 serialization to proceed.
 
SerializedLambda has a readResolve method that looks for
 a (possibly private) static method called
 $deserializeLambda$(SerializedLambda) in the capturing class, invokes
 that with itself as the first argument, and returns the result.  Lambda classes
 implementing $deserializeLambda$ are responsible for validating
 that the properties of the SerializedLambda are consistent with a
 lambda actually captured by that class.
 
The identity of a function object produced by deserializing the serialized
 form is unpredictable, and therefore identity-sensitive operations (such as
 reference equality, object locking, and System.identityHashCode()) may
 produce different results in different implementations, or even upon
 different deserializations in the same implementation.
