Public Attributes
int32	file_id_
	Identifier of the file to download.
int32	priority_
	Priority of the download (1-32). The higher the priority, the earlier the file will be downloaded. If the priorities of two files are equal, then the last one for which downloadFile/addFileToDownloads was called will be downloaded first.
int53	offset_
	The starting position from which the file needs to be downloaded.
int53	limit_
	Number of bytes which need to be downloaded starting from the "offset" position before the download will automatically be canceled; use 0 to download without a limit.
bool	synchronous_
	Pass true to return response only after the file download has succeeded, has failed, has been canceled, or a new downloadFile request with different offset/limit parameters was sent; pass false to return file state immediately, just after the download has been started.

Static Public Attributes
static const std::int32_t	ID = 1059402292
	Identifier uniquely determining a type of the object.
