Detailed Description
A class that implements CAsyncFileWriter::Callback and logs errors and when the pending write limit is reached.Public Member Functions | |
| CLoggingAsyncFileWriterCallback () | |
| CLoggingAsyncFileWriterCallback (const CLoggingAsyncFileWriterCallback &rhs) | |
| CLoggingAsyncFileWriterCallback & | operator= (const CLoggingAsyncFileWriterCallback &rhs) |
| void | OnError (CAsyncFileWriter *pInstance, const JetByteTools::Core::_tstring &where, DWORD lastError) override |
| Called when an error occurs during asynchronous processing or file closure. | |
| void | OnError (CAsyncFileWriter *pInstance, const JetByteTools::Core::_tstring &where, const JetByteTools::Core::_tstring &message) override |
| Called when an error occurs during asynchronous processing or file closure. | |
| void | OnLastWrite (CAsyncFileWriter *pInstance) override |
| Called when the final write occurs after Shutdown() has been called on the file writer. You can use this to take an action with the file writer when the last pending write completes rather than blocking a thread to Wait() for the situation. | |
| void | OnPendingWriteLimit (CAsyncFileWriter *pInstance) override |
| Called when the limit on the number of concurrent pending writes is reached. | |
