Class anonymous_namespace{RelAlgDagBuilder.cpp}::anonymous_namespace{RelAlgDagBuilder.cpp}::CoalesceSecondaryProjectVisitor

class

CoalesceSecondaryProjectVisitor visits each relational algebra expression node in a given input and determines whether or not the input is a candidate for coalescing into the parent RA node. Intended for use only on the inputs of a RelProject node.
