Classes

IAsyncResultAn interface that methods use as a return type in order to provide asynchronous execution of code.
TBitConverterConverter between arrays of bytes and Delphi native types.
TMultiWaitEventAbstract base class that the System.Classes unit fully implements. IAsyncResult.GetAsyncWaitEvent uses this class as the return type.
