## Package com.r3corda.node.utilities

### Types

ANSIProgressObserver | `class ANSIProgressObserver` This observes the StateMachineManager and follows the progress of ProtocolLogics until they complete in the order they are added to the StateMachineManager.
ANSIProgressRenderer | `object ANSIProgressRenderer` Knows how to render a ProgressTracker to the terminal using coloured, emoji-fied output. Useful when writing small command line tools, demos, tests etc. Just set the progressTracker field and it will go ahead and start drawing if the terminal supports it. Otherwise it just prints out the name of the step whenever it changes.
AddOrRemove | `enum class AddOrRemove` Enum for when adding/removing something, for example adding or removing an entry in a directory.
AffinityExecutor | `interface AffinityExecutor : Executor` An extended executor interface that supports thread affinity assertions and short circuiting. This can be useful for ensuring code runs on the right thread, and also for unit testing.
FiberBox | `class FiberBox<T>` Modelled on ThreadBox, but with support for waiting that is compatible with Quasar Fibers and MutableClocks.
JsonSupport | `object JsonSupport` Utilities and serialisers for working with JSON representations of basic types. This adds Jackson support for the java.time API, some core types, and Kotlin data classes.
MutableClock | `abstract class MutableClock : Clock` An abstract class with helper methods for a type of Clock that might have its concept of "now" adjusted externally.

### Extensions for External Classes
