Description copied from interface: EnumerableRel

Creates a plan for this expression according to a calling convention.

Specified by:

implement in interface EnumerableRel

Parameters:

implementor - Implementor

pref - Preferred representation for rows in result expression

Returns:

Plan for this expression according to a calling convention

copy
