The API reference documentation has been created by using doxygen to process comments in the header files. When doxygen generates the html files, it distributes them across a generated file structure to allow for quicker access. This prevents direct linking to the class html files.
When you are asked to read FDO class reference documentation, load the FDO C++ API Reference home page, click the Classes tab in the right-hand pane and click on the class name. The home page is located in the <install directory>/Docs/HTML/FDO_API directory.
