Uses of Iteration in org.eclipse.rdf4j.common.iteration

Subinterfaces of Iteration in org.eclipse.rdf4j.common.iteration

Modifier and Type	Interface and Description
interface	CloseableIteration<E,X extends Exception> An Iteration that can be closed to free resources that it is holding.

Classes in org.eclipse.rdf4j.common.iteration that implement Iteration

Modifier and Type	Class and Description
class	AbstractCloseableIteration<E,X extends Exception> Base class for CloseableIterations offering common functionality.
class	CloseableIterationBase<E,X extends Exception> Deprecated. since 4.0. Use AbstractCloseableIteration instead.
class	CloseableIteratorIteration<E,X extends Exception> An Iteration that can convert an Iterator to a CloseableIteration.
class	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).
class	DelayedIteration<E,X extends Exception> An iteration that delays the creation of the underlying iteration until it is being accessed.
class	DistinctIteration<E,X extends Exception> An Iteration that filters any duplicate elements from an underlying iterator.
class	EmptyIteration<E,X extends Exception> An iterator that does not contain any elements.
class	ExceptionConvertingIteration<E,X extends Exception> A CloseableIteration that converts an arbitrary iteration to an iteration with exceptions of type X.
class	FilterIteration<E,X extends Exception> A CloseableIteration that wraps another Iteration, applying a filter on the objects that are returned.
class	IntersectIteration<E,X extends Exception> An Iteration that returns the intersection of the results of two Iterations.
class	IterationWrapper<E,X extends Exception> Abstract superclass for Iterations that wrap other Iterations.
class	IteratorIteration<E,X extends Exception> An Iteration that can convert an Iterator to a Iteration.
class	LimitIteration<E,X extends Exception> An Iteration that limits the amount of elements that it returns from an underlying Iteration to a fixed amount.
class	LookAheadIteration<E,X extends Exception> An Iteration that looks one element ahead, if necessary, to handle calls to LookAheadIteration.hasNext().
class	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).
class	OffsetIteration<E,X extends Exception> An Iteration that skips the first offset elements from an underlying Iteration.
class	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).
class	ReducedIteration<E,X extends Exception> Removes consecutive duplicates from the object stream.
class	SingletonIteration<E,X extends Exception> An Iteration that contains exactly one element.
class	TimeLimitIteration<E,X extends Exception>
class	UnionIteration<E,X extends Exception> An Iteration that returns the bag union of the results of a number of Iterations.
