## Interface FileSource

-     public interface FileSource

  ### FileSource Operations

  These APIs allow a `DataSource` to be used as a way to store files in a DataSource that might otherwise be stored in a filesystem on the server. They are implemented by sending requests to the server with a special `operationType`.

  FileSource operations use standardized field names: fileName, fileType, fileFormat, fileContents, fileSize, fileLastModified and optionally fileVersion. These are translated on the server to native field names for the `DataSource`, determined according to the DataSource configuration for `fileNameField`, `fileTypeField`, `fileFormatField`, `fileContentsField`, `fileLastModifiedField`, and `fileVersionField`.
