serializableCallable

public static java.util.concurrent.Callable<?> serializableCallable(java.lang.reflect.Constructor<? extends java.util.concurrent.Callable> constructorToUse,
                                                    java.lang.Object... args)
                                                             throws java.lang.IllegalArgumentException

This method should be used to convert a callable that would not normally be serializable, externalizable or streamable but has serializable, externalizable or streamable arguments to a constructor to construct it.

When the call method is called on the callable it will call the provided constructor passing in the given arguments. It will then invoke the call method on resulting callable that was created.

The amount of arguments cannot exceed Byte.MAX_VALUE. Also the constructor cannot exceed Byte.MAX_VALUE position in the constructor array returned from Class.getConstructors()

The amount of arguments must match the amount of arguments required by the constructor. Also the arguments must be compatibile with the types required of the constructor.

Unfortunately it isn't easy to pass a Constructor> so we can't pass back a callable that is properly typed. Also this forces the caller to cast their callable or returned value to the correct type manually.

参数:

constructorToUse - The constructor to use when creating the callable

args - The arguments to pass to the constructor

返回:

The callable that will upon being called will instantiate the given callable using the constructor with the provided arguments and calls the call method

抛出:

java.lang.IllegalArgumentException - This is thrown if the arguments are not serializable, externalizable or streamable. It can be thrown if the constructo is not accessible. It can also be thrown if too many arguments or the constructor is to high up in the constructo array returned by the class.
