Method Details
- onMatch
  
  public void onMatch(RelOptRuleCall call)
  
  Description copied from class: RelOptRule
  
  Receives notification about a rule match. At the time that this method is called, call.rels holds the set of relational expressions which match the operands to the rule; call.rels[0] is the root expression.
  Typically a rule would check that the nodes are valid matches, creates a new expression, then calls back RelOptRuleCall.transformTo(org.apache.calcite.rel.RelNode, java.util.Map<org.apache.calcite.rel.RelNode, org.apache.calcite.rel.RelNode>, org.apache.calcite.plan.RelHintsPropagator) to register the expression.
  Specified by:
  
  onMatch in class RelOptRule
  
  Parameters:
  
  call - Rule call
