Package com.bigdata.striterator

Streaming iterator patterns based on Martyn Cutcher's striterator design but supporting generics and with extensions for closable, chunked, and ordered streaming iterators.

See: Description

Interface Summary

Interface	Description
IChunkConverter<E,F>	This is a chunk at a time type processor.
IChunkedIterator<E>	An iterator that is able visit items in chunks.
IChunkedOrderedIterator<R>	An extension of IChunkedIterator interface that knows about natural traversal orders and how to re-order the elements that are being visited to support JOINs where the natural order for the access paths is different for the left- and right-hand side of the JOIN.
IChunkedOrderedStriterator<I extends IChunkedOrderedIterator<E>,E>	Generic-enabled streaming iterator pattern for chunked ordered iterators.
IChunkedStriterator<I extends IChunkedIterator<E>,E>	Generic-enabled streaming iterator pattern for chunked iterators.
IFilter<I extends Iterator<E>,E,F>	Stackable filter pattern with generics.
IKeyOrder<E>	An interface representing the natural traversal orders for the different indices for some class of relation.
IStriterator<I extends Iterator<E>,E>	Streaming iterator pattern ala Martyn Cutcher with generics.

Class Summary

Class	Description
AbstractChunkedResolverator<E,F,S>	Wraps an IChunkedIterator and asynchronously resolves chunks.
AbstractKeyOrder<E>	Abstract base class provides default behavior for generating keys for a given index order.
Appender<I extends Iterator<E>,E>	Appender pattern tacks on another iterator when the source iterator is exhausted.
ChunkedArrayIterator<E>	Fully buffered iterator.
ChunkedArraysIterator<E>	An iterator that visits the elements in the given iterator of arrays.
ChunkedConvertingIterator<E,F>	Supports the chunk-at-a-time filter and conversion operations.
ChunkedFilter<I extends IChunkedIterator<E>,E,F>	Chunk-at-a-time filter.
ChunkedOrderedStriterator<I extends IChunkedOrderedIterator<E>,E>	Chunked ordered streaming iterator.
ChunkedResolvingIterator<E,S>	Converts the type of the source iterator using ChunkedResolvingIterator.resolve(Object).
ChunkedStriterator<I extends IChunkedIterator<E>,E>	Chunked streaming iterator.
ChunkedWrappedIterator<E>	Converts an Iterator into chunked iterator.
Chunkerator<E>	Iterator "chunks" up another iterator, visiting arrays of elements at a time.
ClosableEmptyIterator<E>	A closable iterator that visits nothing.
ClosableSingleItemIterator<E>	A closable iterator that visits a single item.
CloseableChunkedIteratorWrapperConverter<E>	A fly weight conversion that wraps a normal IChunkedIterator as an ICloseableIterator visiting the source iterator's chunks, i.e., this converts between an IChunkedIterator and an Iterator visiting chunks.
CloseableIteratorWrapper<E>	Wraps a normal Iterator as an ICloseableIterator.
Dechunkerator<E>	Wrap an iterator visiting chunks as an iterator visiting the individual elements in each chunk.
DelegateChunkedIterator<E>	Abstract class for delegation patterns for chunked iterators.
DistinctFilter<E>	Deprecated by JVMDistinctBindingSetsOp
EmptyChunkedIterator<E>	An empty iterator.
Filter<I extends Iterator<E>,E>	Element-at-a-time filter with generics.
GenericChunkedOrderedStriterator<E>	Chunked ordered streaming iterator class that supresses generic types.
GenericChunkedStriterator<E>	Chunked streaming iterator class that supresses generic types.
GenericStriterator<E>	Streaming iterator class that suppresses generic types.
MergeFilter<I extends Iterator<E>,E extends Comparable<E>>	Merge sort of two iterators with duplicates suppressed.
PushbackIterator<E>	Allows pushback of the most recently visited element onto the iterator.
Resolver<I extends Iterator<E>,E,F>	Pattern for resolving elements of an iterator.
SingleValueChunkedIterator<E>	An iterator that will visit a single value.
Striterator<I extends Iterator<E>,E>	Streaming iterator pattern.
TestAll	Aggregates test suites into increasing dependency order.
TestAppendFilter	Unit tests for Appender.
TestChunkedFilter	Unit tests for ChunkedFilter.
TestCloseableChunkedIteratorWrapperConverter	Test suite for CloseableChunkedIteratorWrapperConverter.
TestDechunkerator	Test suite for Dechunkerator.
TestDistinctFilter	Unit tests for DistinctFilter.
TestMergeFilter	Unit tests for MergeFilter.
TestPushbackIterator	Unit test for PushbackIterator.
TestResolver	Unit tests for Resolver.
