Package org.ehrbase.aql.compiler

Class QueryCompilerPass1

java.lang.Object

org.ehrbase.aql.parser.AqlBaseListener

org.ehrbase.aql.compiler.QueryCompilerPass1

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeListener, AqlListener

public class QueryCompilerPass1
extends AqlBaseListener

AQL compilation pass 1
This pass consists in evaluating the CONTAINS clauses and generate an internal representation of the contain expressions and operators. The internal representation is then translated into a SQL equivalent from the containment index. Created by christian on 4/1/2016.
