All Implemented Interfaces:

Serializable, PlatformSecurityAwareJob

Direct Known Subclasses:

PlatformCallable, PlatformRunnable
```
public abstract class PlatformAbstractFunc
extends Object
implements PlatformSecurityAwareJob, Serializable
```
Base class for simple computations (Callable, Runnable). Cleaner alternative to PlatformClosureJob, uses less wrapping for the underlying object, and a single callback.
