Detailed Description

template<class Sample, class Field>
class OpenDDS::DCPS::StructComparator< Sample, Field >

deal with nested structs, for example: struct A { long x; }; struct B { A theA; }; B's query string has "ORDER BY theA.x" The generated code will create a StructComparator with Sample = B and Field = A which in turn has a "delegate" which is a FieldComparator (see above) with Sample = A and Field = CORBA::Long
