CRecordFileStoreStoreChunk

This is an internal message from FileStores.

This message is used when files are transferred from one FileStore to another. Files are not transferred in one piece but in blocks (Default: 10000 bytes per block). This specific message is used to transfer a single file block.

Record Usage

In nyssr.net, we typically don't exchange interfaces between projects. Instead, we use platform-independent Records to describe message formats.

One or more descriptions of these Records are stored in the JSON or XML format as record.json or record.xml within a directory. The Record Generator, an included Swing tool, generates helper classes from these files. These classes can then be used to type-safely write or read messages.
