Detailed Description

Class to handle lookup or indexing into an MS OBSERVATION subtable.

Intended use:

Public interface

Review Status

Date Reviewed:



From "MeasurementSet", "OBSERVATION subtable" and "index".


This class provides lookup and indexing into an MS OBSERVATION subtable. These services include returning rows numbers (which for the OBSERVATION subtable are OBSERVATION_ID's) associated with specific data in the subtable.



Collect together all subtable indexing and lookup for the OBSERVATION subtable, for encapsulation and efficiency.
