Class S_Else

java.lang.Object

org.aksw.sparqlify.algebra.sql.exprs2.SqlExprBase

org.aksw.sparqlify.algebra.sql.exprs2.SqlExprFunctionBase

org.aksw.sparqlify.algebra.sql.exprs2.SqlExpr1

org.aksw.sparqlify.algebra.sql.exprs2.S_Else

All Implemented Interfaces:

SqlExpr, SqlExprFunction

public class S_Else
extends SqlExpr1

This is a hack (or at least trick) to treat CASE ... WHEN statements as functions Maybe not the best choice to do it like this.
