Class BshLambda

java.lang.Object

bsh.BshLambda

All Implemented Interfaces:

java.io.Serializable

public class BshLambda
extends java.lang.Object
implements java.io.Serializable

The runtime value of a lambda expression. Opaque until coerced to a functional interface, either by a cast or assignment (convertTo(java.lang.Class<T>)) or by overload resolution matching its arity marker (castLambda(java.lang.Class<?>, java.lang.Class<?>, java.lang.Object, boolean)).

Public only because generated wrapper classes, defined in other class loaders, must call invoke(java.lang.Object[], java.lang.Class<T>, java.lang.Class<?>[]); it is not a supported API. Script errors and undeclared checked exceptions reach Java callers of a wrapper as RuntimeEvalError; unchecked exceptions and declared checked exceptions reach them as themselves.

public final <T> T invoke(java.lang.Object[] args,

                          java.lang.Class<?>[] declaredExceptions)

Called by generated wrappers; public because they live in another class loader. A generated SAM declares no EvalError, so errors go unchecked.

serializedForm

public final java.lang.Object serializedForm(java.lang.Class<?> functionalInterface)

Called by a generated wrapper's writeReplace; public for the same reason as invoke.
