Subclasses of OpBase in com.hp.hpl.jena.sparql.algebra.op
 class Op0
          Super class for operators that do not combine other operators
 class Op1
          Super class for operators that operate on a single sub-operation (i.e.
 class Op2
          Super class for operators that combine two sub-operators
 class OpAssign
           
 class OpBGP
           
 class OpConditional
          Conditional execution - works with streamed execution and is known to safe to evaluate that way (no issues from nested optionals).
 class OpDatasetNames
           
 class OpDiff
           
 class OpDisjunction
          N-way disjunction.
 class OpDistinct
           
 class OpExt
          Marker for extension points Execution will be per-engine specific
 class OpExtend
          This is the operation in stadard SPARQL 1.1 OpAssign is specifically in support of LET.
 class OpFetch
           
 class OpFilter
           
 class OpGraph
           
 class OpGroup
           
 class OpJoin
           
 class OpLabel
          Do-nothing class that means that tags/labels/comments can be left in the algebra tree.
 class OpLeftJoin
           
 class OpList
           
 class OpMinus
           
 class OpModifier
          Mark solution modifiers
 class OpN
           
 class OpNull
           
 class OpOrder
           
 class OpPath
           
 class 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.
 class OpProject
           
 class OpPropFunc
          Property functions (or any OpBGP replacement) Execution will be per-engine specific
 class OpQuad
          Algebra operation for a single quad.
 class OpQuadPattern
           
 class OpReduced
           
 class 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).
 class OpService
           
 class OpSlice
           
 class OpTable
           
 class OpTopN
          Top N from a stream of items - for small N, better than ORDER BY + LIMIT N
 class OpTriple
          Algebra operation for a single triple.
 class OpUnion
