Examples of JoinInfo

com.alvazan.orm.parser.antlr.JoinInfo
org.eigenbase.rel.JoinInfo
An analyzed join condition.
It is useful for the many algorithms that care whether a join is an equi-join.
You can create one using {@link #of}, or call {@link JoinRelBase#analyzeCondition()}; many kinds of join cache their join info, especially those that are equi-joins and sub-class {@link org.eigenbase.rel.rules.EquiJoinRel}.
@see JoinRelBase#analyzeCondition()
