Uses of ExprSqlRewrite in org.aksw.sparqlify.core.algorithms

Methods in org.aksw.sparqlify.core.algorithms that return ExprSqlRewrite

Modifier and Type	Method and Description
ExprSqlRewrite	MappingOpsImpl.rewrite(com.hp.hpl.jena.sdb.core.Gensym gensym, com.hp.hpl.jena.sparql.expr.aggregate.AggCount agg)
static ExprSqlRewrite	MappingOpsImpl.rewrite(Mapping mapping, com.hp.hpl.jena.sparql.expr.aggregate.Aggregator agg, com.hp.hpl.jena.sdb.core.Generator generator, TypeSystem typeSystem, SqlTranslator sqlTranslator) TODO: Without the toDouble coercion, SUM(int) will be discarded even after already been found out as a candidate.
ExprSqlRewrite	MappingOpsImpl.rewriteOld(com.hp.hpl.jena.sdb.core.Gensym gensym, com.hp.hpl.jena.sparql.expr.aggregate.Aggregator agg) Returns a pair comprised of: - A SPARQL expression that references the SQL column of the aggregater - A projection // Ignore: the typeMap is implied by the projection - A type map
ExprSqlRewrite	SqlTranslatorImpl.translate(com.hp.hpl.jena.sparql.expr.Expr expr, Map<com.hp.hpl.jena.sparql.core.Var,com.hp.hpl.jena.sparql.expr.Expr> binding, Map<String,TypeToken> typeMap) Deprecated.
ExprSqlRewrite	MappingOpsImpl.unifyAlternatives(com.hp.hpl.jena.sparql.expr.Expr e, Mapping source) Two variants: - create a case-block for each expression - create a union - but with the union we would eval the expression over and over again - so we go with the case block

Methods in org.aksw.sparqlify.core.cast that return ExprSqlRewrite

Modifier and Type	Method and Description
ExprSqlRewrite	TypedExprTransformer.rewrite(com.hp.hpl.jena.sparql.expr.Expr expr, Map<String,TypeToken> typeMap)
ExprSqlRewrite	TypedExprTransformerImpl.rewrite(com.hp.hpl.jena.sparql.expr.Expr expr, Map<String,TypeToken> typeMap)

Uses of ExprSqlRewrite in org.aksw.sparqlify.core.interfaces

Methods in org.aksw.sparqlify.core.interfaces that return ExprSqlRewrite

Modifier and Type	Method and Description
ExprSqlRewrite	SqlTranslator.translate(com.hp.hpl.jena.sparql.expr.Expr sparqlExpr, Map<com.hp.hpl.jena.sparql.core.Var,com.hp.hpl.jena.sparql.expr.Expr> binding, Map<String,TypeToken> typeMap) We use the same Expr object for translating expressions.

Uses of ExprSqlRewrite in org.aksw.sparqlify.util

Methods in org.aksw.sparqlify.util that return ExprSqlRewrite

Modifier and Type

Method and Description

ExprSqlRewrite

SqlTranslatorImpl2.translate(com.hp.hpl.jena.sparql.expr.Expr sparqlExpr, Map<com.hp.hpl.jena.sparql.core.Var,com.hp.hpl.jena.sparql.expr.Expr> binding, Map<String,TypeToken> typeMap) TODO: There are two use cases: a) Rewrite an expression completely to SQL -> result is an SqlExpr object b) Partially rewrite an expression to SQL -> result is an SqlExprRewrite object I think the interface should return the SqlExprRewrite and a static helper function then extracts the SqlExpr from it

Methods in org.aksw.sparqlify.util with parameters of type ExprSqlRewrite

Modifier and Type	Method and Description
static SqlExpr	SqlTranslatorImpl2.asSqlExpr(ExprSqlRewrite rewrite) Assumes that the rewrite's root expression is of type E_RdfTerm.
static SqlExpr	SqlTranslatorImpl2.asSqlExprOld(ExprSqlRewrite rewrite)
