Interface RestrictedMarkResetIterator<T>

All Superinterfaces:

AutoCloseable, CloseableIterator<T>, Copyable<MarkResetIterator<T>>, Iterator<T>, MarkResetIterator<T>, ResettableIterator<T>

All Known Implementing Classes:

MarkResetSkippingIterator, SpoolingMarkResetIterator

public interface RestrictedMarkResetIterator<T>
extends MarkResetIterator<T>

An extension to the base interface to support restrictions on the base iterator, for example, to implement the mark-reset behaviour for the cross phase of the merge join. In that case the predicate would restrict the base iterator to the current value of the join key.
