Constructor Detail

LcsRowScanRel

public LcsRowScanRel(RelOptCluster cluster,
                     RelNode[] children,
                     LcsTable lcsTable,
                     List<FemLocalIndex> clusteredIndexes,
                     RelOptConnection connection,
                     Integer[] projectedColumns,
                     boolean isFullScan,
                     Integer[] resCols,
                     double inputSelectivity)

Creates a new LcsRowScanRel object.

Parameters:

cluster - RelOptCluster for this rel

children - children inputs into the row scan

lcsTable - table being scanned

clusteredIndexes - clusters to use for table access

connection - connection

projectedColumns - array of 0-based table-relative column ordinals, or null to project all columns

isFullScan - true if doing a full scan of the table

resCols - residual filter columns

Method Detail

clone

public LcsRowScanRel clone()

Description copied from interface: RelNode

Clones this RelNode.

Traits of the RelNode must be explicitly cloned, using AbstractRelNode.inheritTraitsFrom(AbstractRelNode), as the RelNode may have traits of which it has no knowledge. Example implementation:

     public MyRelNode clone()
     {
         MyRelNode clone = new MyRelNode(...);
         clone.inheritTraitsFrom(this);
         return clone;
     }
 

N.B.: This method must be overridden whenever an existing, concrete RelNode is extended. Otherwise, calling clone() will produce a differently typed RelNode, resulting in invalid or incorrect query plans.

Specified by:

clone in interface RelNode

Specified by:

clone in class AbstractRelNode

Returns:

a clone of this RelNode
