Class JoinInfo


public class JoinInfo extends Object
An analyzed join condition.

It is useful for the many algorithms that care whether a join has an equi-join condition.

You can create one using of(org.apache.calcite.rel.RelNode, org.apache.calcite.rel.RelNode, org.apache.calcite.rex.RexNode), or call Join.analyzeCondition(); many kinds of join cache their join info, especially those that are equi-joins.
