Detailed Description

"Pimpl idiom" (pointer to implementation idiom). The UHD_PIMPL_* macros simplify code overhead for declaring and making pimpls.

Each pimpl is implemented as a shared pointer to the implementation:

  • The container class will not have to deallocate the pimpl.
  • The container class will use the pimpl as a regular pointer.
  • Usage: _impl->method(arg0, arg1)
  • Usage: _impl->member = value;
