63 // This class provides lookup and indexing into an MS POLARIZATION
64 // subtable. These services include returning rows numbers
65 // (which for the POLARIZATION subtable are POLARIZATION_ID's) associated
66 // with specific data in the subtable.

73 // Collect together all subtable indexing and lookup for the
74 // POLARIZATION subtable, for encapsulation and efficiency.
