Interface Summary

Interface	Description
Destination	Defines an object which can return an output stream, and hence represents the potential destination of a stream of data.
IOConsumer<T>	Consumer-like interface that allows an IOException to be thrown.
IOFunction<T,R>	Function-like interface that allows an IOException to be thrown.
IORunnable	Runnable-like interface that allows an IOException to be thrown.
IOSupplier<T>	Supplier-like interface that allows an IOException to be thrown.
NodeDescendants.Visitor	The Visitor processes a single node in a tree.
Sequence	Utility sub-interface of Splittable suitable for use with splittable data that can be iterated over.
SplitCollector<S extends Splittable<S>,A>	Defines an object that can collect values from a Splittable into an accumulator.
Splittable<S extends Splittable<S>>	Defines an object which can be split into two for subdivided processing.
Wrapper	Mixin interface which indicates an object built on top of a base object.
XMLEncodeDecode	Interface for objects that can encode and decode their internal configuration within the content of an Element.
