Constructor Details

EnumerableSort

public EnumerableSort(RelOptCluster cluster,
 RelTraitSet traitSet,
 RelNode input,
 RelCollation collation,
 @Nullable RexNode offset,
 @Nullable RexNode fetch)

Creates an EnumerableSort.

Use create(org.apache.calcite.rel.RelNode, org.apache.calcite.rel.RelCollation, org.apache.calcite.rex.RexNode, org.apache.calcite.rex.RexNode) unless you know what you're doing.

Method Details
