com.bigdata.bop |
This package provides an API for query operators.
|
com.bigdata.bop.controller |
This package provides operators for subquery, including UNION, STEPS,
and STAR (transitive closure).
|
com.bigdata.bop.join | |
com.bigdata.rdf.sparql.ast.service |
This package provides support for SPARQL 1.1 Federated Query, including the
special case of "service" end points which live within the same JVM and use
direct method calls rather than SPARQL Query and remote (HTTP) end points
for which we will generate an appropriate SPARQL query.
|
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.
