IProgressHandlerV2 Interface

Let a class implement this interface to be able to pass the class instance as a parameter to for example LZMA compressor to let the class get progress callbacks.

A Interface is nothing but a promise, a promise that a class implements a certain interface. So any class that implements IProgressHandlerV2 is only promising to implement the methods that the IProgressHandlerV2 interface describes.

interface IProgressHandlerV2


OnProgressAlgorithms that use the IProgressHandlerV2 interface will call this method when they want to give a notice of a progress.
