jdk.lang.invoke.SerializedLambda — clojure-interop/java.lang.invoke 1.0.5

Serialized form of a lambda expression. The properties of this class represent the information that is present at the lambda factory site, including static metafactory arguments such as the identity of the primary functional interface method and the identity of the implementation method, as well as dynamic metafactory arguments such as values captured from the lexical scope at the time of lambda capture.

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.

Constructor.

Create a SerializedLambda from the low-level information present at the lambda factory site.

capturing-class - The class in which the lambda expression appears - java.lang.Class functional-interface-class - Name, in slash-delimited form, of static type of the returned lambda object - java.lang.String functional-interface-method-name - Name of the functional interface method for the present at the lambda factory site - java.lang.String functional-interface-method-signature - Signature of the functional interface method present at the lambda factory site - java.lang.String impl-method-kind - Method handle kind for the implementation method - int impl-class - Name, in slash-delimited form, for the class holding the implementation method - java.lang.String impl-method-name - Name of the implementation method - java.lang.String impl-method-signature - Signature of the implementation method - java.lang.String instantiated-method-type - The signature of the primary functional interface method after type variables are substituted with their instantiation from the capture site - java.lang.String captured-args - The dynamic arguments to the lambda factory site, which represent variables captured by the lambda - java.lang.Object[]
