Field Details

parentCxt

protected MappingCxt parentCxt

Reference to the triples map that acts as the _child_ of rr:joins

triplesMap

protected org.aksw.rmltk.model.backbone.common.ITriplesMap triplesMap

triplesMapVar

protected org.apache.jena.sparql.core.Var triplesMapVar

exprDag

protected org.aksw.commons.util.algebra.GenericDag<org.apache.jena.sparql.expr.Expr,org.apache.jena.sparql.core.Var> exprDag

Data structure to factor out common subexpressions eagerly

termMapToVar

protected Map<org.aksw.rmltk.model.backbone.common.ITermSpec,org.apache.jena.sparql.core.Var> termMapToVar

quadAcc

protected org.apache.jena.sparql.modify.request.QuadAcc quadAcc

varGen

protected org.apache.jena.sparql.core.VarAlloc varGen

joins

protected List<JoinDeclaration> joins

referenceResolver

protected Function<String,org.apache.jena.sparql.expr.Expr> referenceResolver

The reference resolver can be set after context creation. In the case of RML it needs information from the context.

sourceIdentityResolver

protected Function<org.aksw.rmltk.model.backbone.common.ITriplesMap,Object> sourceIdentityResolver
