public DefaultEmitter(Type targetType)

Writes the instructions that read this value from the current row.

public override void Emit(ColumnInfo[] cols, Generator generator, NullSetPoint nullSetPoint)

cols ColumnInfo[]: The columns the result carries.
generator Generator: The instruction writer to use.
nullSetPoint NullSetPoint: Where to jump when a value is NULL and the object must collapse.

Returns whether this plan reads columns in increasing order. Update previousIndex with the final column used.

public override bool IsSequencial(ref int previousIndex)

Returns whether this plan can collapse its owning object when it reads a NULL.

public override bool NeedNullSetPoint(ColumnInfo[] cols)
