Classes in com.hp.hpl.jena.sparql.algebra.op used by com.hp.hpl.jena.sparql.algebra

Class and Description
Op1 Super class for operators that operate on a single sub-operation (i.e.
OpAssign
OpBGP
OpConditional Conditional execution - works with streamed execution and is known to safe to evaluate that way (no issues from nested optionals).
OpDatasetNames
OpDiff
OpDisjunction N-way disjunction.
OpDistinct
OpExt Marker for extension points Execution will be per-engine specific
OpExtend This is the operation in stadard SPARQL 1.1 OpAssign is specifically in support of LET.
OpFilter
OpGraph
OpGroup
OpJoin
OpLabel Do-nothing class that means that tags/labels/comments can be left in the algebra tree.
OpLeftJoin
OpList
OpMinus
OpNull
OpOrder
OpPath
OpProcedure General procedure in algebra evaluation (a stored procedure facility) Syntax (ARQ extension): CALL (?x, ?y+3) See also the similary algebra form for property functions.
OpProject
OpPropFunc Property functions (or any OpBGP replacement) Execution will be per-engine specific
OpQuad Algebra operation for a single quad.
OpQuadPattern
OpReduced
OpSequence A "sequence" is a join-like operation where it is know that the the output of one step can be fed into the input of the next (that is, no scoping issues arise).
OpService
OpSlice
OpTable
OpTopN Top N from a stream of items - for small N, better than ORDER BY + LIMIT N
OpTriple Algebra operation for a single triple.
OpUnion
