Examples of warrenfalk.lzma.LzmaOutputStream

warrenfalk.lzma.LzmaOutputStream
This particular implementation exposes an output stream which, when written to, exposes its data as an input stream to an Lzma SDK encoder on another thread. The drawback of this is that exceptions on the lzma encoding (output stream) side of the operation are not thrown in the thread that's supplying them with data as is usually the case, so these will be marshaled to the calling thread and rethrown at the next available opportunity (i.e. next client call). You must call close() when completed writing data to ensure you receive any exception which occurs in the output thread. The close() call will block until the operation is completed (either successfully or with failure) @author warren
