Packages that use IChunkedIterator

Package	Description
com.bigdata.bop	This package provides an API for query operators.
com.bigdata.rdf.inf	This package provides an eager closure inference engine for most of the RDF and RDFS entailments and can be used to realize entailments for owl:sameAs, owl:equivilentClass, and owl:equivilentProperty.
com.bigdata.rdf.spo	This package defines a statement model using long term identifiers rather than RDF Value objects.
com.bigdata.rdf.store	This package provides several realizations of an RDF database using the bigdata architecture, including one suitable for temporary data, one suitable for local processing (single host), and one designed for scale-out on commodity hardware.
com.bigdata.relation.accesspath	This package includes an abstraction layer for efficient access paths, including chunked iterators, blocking buffers, and an abstraction corresponding to the natural order of an index.
com.bigdata.service.proxy	This package provides implementations of proxy objects for commonly used classes.
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.
