Constructor Detail

EnumerableSort

public EnumerableSort(RelOptCluster cluster,
                      RelTraitSet traitSet,
                      RelNode input,
                      RelCollation collation,
                      RexNode offset,
                      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.
