LambdaDeserializer
This class is only intended to be called by synthetic$deserializeLambda$ method that the Scala 2.12 compiler will add to classes hosting lambdas.
It is not intended to be consumed directly.

Deserialize a lambda by callingLambdaMetafactory.altMetafactory to spin up a lambda class and instantiating this class with the captured arguments.
Deserialize a lambda by callingLambdaMetafactory.altMetafactory to spin up a lambda class and instantiating this class with the captured arguments.
A cache may be provided to ensure that subsequent deserialization of the same lambda expression is cheap, it amounts to a reflective call to the constructor of the previously created class. However, deserialization of the same lambda expression is not guaranteed to use the same class, concurrent deserialization of the same lambda expression may spin up more than one class.
Assumptions: - No additional marker interfaces are required beyondjava.io.Serializable. These are not stored inSerializedLambda, so we can't reconstitute them. - No additional bridge methods are passed toaltMetafactory. Again, these are not stored.
Value parameters
- cache
A cache used to avoid spinning up a class for each deserialization of a given lambda. May be
null- lookup
The factory for method handles. Must have access to the implementation method, the functional interface class, and
java.io.Serializable.- serialized
The lambda to deserialize. Note that this is typically created by the
readResolvemember of the anonymous class created byLambdaMetaFactory.
