Type Parameters:
  `Value` -

    public abstract class SingleValueCloseableIterator<Value>

extends SingleValueIterator<Value>
implements CloseableIterator<Value>

SingleValueIterator is a utility class used for quickly presenting a single value to a consumer expecting both a `Closeable` and an `Iterator` interface. After returning the Value value via `SingleValueIterator.next()`, `SingleValueIterator.hasNext()` will return `false`.

This class is especially useful if you do not wish to create a `Collection` to hold a single value in which to create an Iterator.
