Class ResolvedTuple.ResolvedMap

java.lang.Object

org.apache.drill.exec.physical.impl.scan.project.ResolvedTuple

org.apache.drill.exec.physical.impl.scan.project.ResolvedTuple.ResolvedMap

All Implemented Interfaces:

VectorSource

Direct Known Subclasses:

ResolvedTuple.ResolvedMapArray, ResolvedTuple.ResolvedSingleMap

Enclosing class:

ResolvedTuple

public abstract static class ResolvedTuple.ResolvedMap
extends ResolvedTuple

Represents a map implied by the project list, whether or not the map actually appears in the table schema. The column is implied to be a map because it contains children. This implementation builds the map and its children.
