Interface Summary

Interface	Description
CloseableIteration<E,X extends Exception>	An Iteration that can be closed to free resources that it is holding.
Iteration<E,X extends Exception>	An Iteration is a typed Iterator-like object that can throw (typed) Exceptions while iterating.

Class Summary

Class	Description
AbstractCloseableIteration<E,X extends Exception>	Base class for CloseableIterations offering common functionality.
CloseableIteratorIteration<E,X extends Exception>	An Iteration that can convert an Iterator to a CloseableIteration.
ConvertingIteration<S,T,X extends Exception>	A CloseableIteration that converts an iteration over objects of type S (the source type) to an iteration over objects of type T (the target type).
DelayedIteration<E,X extends Exception>	An iteration that delays the creation of the underlying iteration until it is being accessed.
DistinctIteration<E,X extends Exception>	An Iteration that filters any duplicate elements from an underlying iterator.
EmptyIteration<E,X extends Exception>	An iterator that does not contain any elements.
ExceptionConvertingIteration<E,X extends Exception>	A CloseableIteration that converts an arbitrary iteration to an iteration with exceptions of type X.
FilterIteration<E,X extends Exception>	A CloseableIteration that wraps another Iteration, applying a filter on the objects that are returned.
IntersectIteration<E,X extends Exception>	An Iteration that returns the intersection of the results of two Iterations.
Iterations	This class consists exclusively of static methods that operate on or return Iterations.
IterationSpliterator<T>	A Spliterator implementation that wraps an Iteration.
IterationWrapper<E,X extends Exception>	Abstract superclass for Iterations that wrap other Iterations.
IteratorIteration<E,X extends Exception>	An Iteration that can convert an Iterator to a Iteration.
LimitIteration<E,X extends Exception>	An Iteration that limits the amount of elements that it returns from an underlying Iteration to a fixed amount.
LookAheadIteration<E,X extends Exception>	An Iteration that looks one element ahead, if necessary, to handle calls to LookAheadIteration.hasNext().
MinusIteration<E,X extends Exception>	An Iteration that returns the results of an Iteration (the left argument) minus the results of another Iteration (the right argument).
OffsetIteration<E,X extends Exception>	An Iteration that skips the first offset elements from an underlying Iteration.
QueueIteration<E,T extends Exception>	Makes working with a queue easier by adding the methods QueueIteration.done() and QueueIteration.toss(Exception) and after converting the Exception to the required type using QueueIteration.convert(Exception).
ReducedIteration<E,X extends Exception>	Removes consecutive duplicates from the object stream.
SilentIteration<T,E extends Exception>	An IterationWrapper that silently ignores any errors that occur during processing.
SingletonIteration<E,X extends Exception>	An Iteration that contains exactly one element.
TimeLimitIteration<E,X extends Exception>
UnionIteration<E,X extends Exception>	An Iteration that returns the bag union of the results of a number of Iterations.
