示例1: onMatch
import org.apache.calcite.rel.core.Sort; //导入方法依赖的package包/类
@Override
public void onMatch(RelOptRuleCall call) {
final Sort sort = call.rel(0);
if (sort.offset == null && sort.fetch == null) {
return;
}
RelTraitSet origTraitSet = sort.getTraitSet();
RelTraitSet traitSet = origTraitSet.replace(OLAPRel.CONVENTION).simplify();
RelNode input = sort.getInput();
if (!sort.getCollation().getFieldCollations().isEmpty()) {
// Create a sort with the same sort key, but no offset or fetch.
input = sort.copy(sort.getTraitSet(), input, sort.getCollation(), null, null);
}
RelNode x = convert(input, input.getTraitSet().replace(OLAPRel.CONVENTION));
call.transformTo(new OLAPLimitRel(sort.getCluster(), traitSet, x, sort.offset, sort.fetch));
}
示例2: onMatch
