Low Level Utilities

The Low Level Utilities package is a runtime package containing three classes that are used by the other packages on my Delphi Website. 

• TFastCollection behaves exactly like TCollection but contains a workaround that vastly speeds up clearing large collections.
  
  
• TCallbackComponent can be used as a base for invisible components that require a window handle.
  
  
• TExRegistry, derived from TRegistry provides additional registry handling capabilities, including  support for Multi String values, and importing and exporting regedit compatible .REG files
