Detailed Description

Any custom dataloader must derive from BaseImplDataLoader, For convenience, If dataloader is in sync mode, user can also derive from SyncImplDataLoader.

For custom lib implementation, user need to implement the following virtual functions: startImpl(), // user also need setCaps(port) in startImpl stopImpl(), // stop all resources for dataloader readDataImpl(), // read data in sync mode, return kEndOfStream if end of stream. readDataAsyncImpl(dataReadyCb), // read data in async mode. Once data is ready, need call dataReadyCb(datamap) to notify application flushImpl(), // flush data in process
