Detailed Description

Class used to upload a GridFS file.

Constructor & Destructor Documentation

uploader()

mongocxx::v_noabi::gridfs::uploader::uploader ( )

noexcept

Default constructs an uploader object.

The uploader is equivalent to the state of a moved from uploader. The only valid actions to take with a default constructed uploader are to assign to it, or destroy it.

Member Function Documentation

abort()

void mongocxx::v_noabi::gridfs::uploader::abort

(

)

Aborts uploading the file.

Exceptions

mongocxx::v_noabi::logic_error	if the upload stream was already closed.
mongocxx::v_noabi::bulk_write_exception	if an error occurs when removing chunk data from the database.

chunk_size()

std::int32_t mongocxx::v_noabi::gridfs::uploader::chunk_size

(

)

const

Gets the chunk size of the file being uploaded.

Returns

The chunk size in bytes.

close()

result::gridfs::upload mongocxx::v_noabi::gridfs::uploader::close

(

)

Closes the uploader stream.

Exceptions

mongocxx::v_noabi::logic_error	if the upload stream was already closed.
mongocxx::v_noabi::bulk_write_exception	if an error occurs when writing chunk data or file metadata to the database.
mongocxx::v_noabi::gridfs_exception	if the uploader requires more than 2^31-1 chunks to store the file at the requested chunk size.

write()

void mongocxx::v_noabi::gridfs::uploader::write	(	const std::uint8_t *	bytes,
		std::size_t	length
	)

Writes a specified number of bytes to a GridFS file.

Parameters

bytes	A pointer to the bytes to write.
length	The number of bytes to write.

Exceptions

mongocxx::v_noabi::logic_error	if the upload stream was already closed.
mongocxx::v_noabi::bulk_write_exception	if an error occurs when writing chunk data to the database.
mongocxx::v_noabi::gridfs_exception	if the uploader requires more than 2^31-1 chunks to store the file at the requested chunk size.
