Uses of OpBase in org.apache.jena.sparql.algebra.op

Subclasses of OpBase in org.apache.jena.sparql.algebra.op

Modifier and Type	Class	Description
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. a table or sequence))
class	Op2	Super class for operators that combine two sub-operators
class	OpAntiJoin
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	OpDisjunction	N-way disjunction.
class	OpDistinct
class	OpDistinctReduced
class	OpExt	Marker for extension points Execution will be per-engine specific
class	OpExtend	This is the operation in standard SPARQL 1.1 OpAssign is specifically in support of LET.
class	OpExtendAssign
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	OpLateral
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 <iri>(?x, ?y+3).
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	OpQuadBlock	A list of quads.
class	OpQuadPattern	The main Op used in converting SPARQL algebra to quad form.
class	OpReduced
class	OpSemiJoin
class	OpSequence	A "sequence" is a join-like operation where it is known that 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	OpUnfold
class	OpUnion
