This block of code appears to be part of a C++ interface or base class that works with disk-related functionality. Here's what each portion of the code does:

1. GetCurrentLoadedDisk:

   const char* GetCurrentLoadedDisk() { return current_disk_path_.c_str(); };
   

   • This function returns the current disk's file path as a C-style string (const char*).
   • current_disk_path_ is likely a member variable of the class (probably a std::string), and .c_str() converts it into a const char* for use in contexts that require a C-style string.

2. FilterSide:

   virtual IDisk::FaceSelection FilterSide(IDisk::FaceSelection face_selection);
   

   • This is a pure or virtual method (depending on whether a definition exists) that takes a parameter of type IDisk::FaceSelection (possibly an enum or similar type).
   • It likely processes or determines something about the "face selection" of the disk (e.g., which side or face of a disk is being referenced).

3. SetWrite:

   virtual void SetWrite(int side, unsigned int track);
   

   • This virtual function enables writing to the specified disk side (int side) and track (unsigned int track).
   • It's likely meant to prepare a system for writing data to the designated location on the disk.

4. DumpTrack:

   virtual void DumpTrack(int side, unsigned int track, int rev = 0);
   

   • This virtual function is used to "dump" the data (or contents) of a specific track of the disk.
   • The first parameter specifies the side of the disk (int side), and the second specifies the track (unsigned int track).
   • The int rev = 0 parameter may indicate which revision or pass of the track to dump, with a default value of 0 (if not supplied).

5. DumpTrackRev:

   virtual void DumpTrackRev(int side, unsigned int track, int rev);
   

   • Similar to DumpTrack, but it explicitly requires the revision (int rev) as an input parameter.

Summary:

This code defines a set of methods, likely as part of a base class or interface, for interacting with a disk.

• GetCurrentLoadedDisk: Retrieves the current loaded disk's path.
• FilterSide: Allows for filtering or selection based on the disk's side (and perhaps validates it).
• SetWrite: Prepares for writing on a specific side and track of the disk.
• DumpTrack and DumpTrackRev: Handle dumping the contents of a specified disk track, with DumpTrackRev allowing explicit revision control.
