instantiate

public static <T> T instantiate(Class<T> type,

                         throws IOException

Convenience method for testing implementing class constructor signature compliance.

De-serializers are free to implement higher performance instantiation that complies with this contract.

Only public and package default constructors can be called by de-serializers. Package default constructors have been provided to prevent implementations from polluting public api, but should be treated as public constructors.

Constructors with private visibility cannot be called.

Constructors with protected visibility can only be called by subclasses, not de-serializers.

Type Parameters:

T - AtomicExternal implementation type.

Parameters:

type - AtomicExternal implementing class.

arg - ObjectInput argument to pass to implementing constructor.

Returns:

new instance of T.

Throws:

InvalidClassException - if constructor is non compliant or doesn't exist.

InvalidObjectException - if invariant check fails

NullPointerException - if arg or type is null.

IOException
