)

Member Function Documentation

void mongo::GridFileBuilder::appendChunk	(	const char *	data,
		size_t	length
	)

Appends a chunk of data.

Data will be split as many times as necessary in chunkSize blocks. Sizes not multiple of chunkSize will copy the reamining bytes to a pendingData pointer. In this way, it is possible to add data in a stream fashion way.

Parameters

data	- C string with data
length	- size of the string

mongo::BSONObj mongo::GridFileBuilder::buildFile	(	const std::string &	remoteName,
		const std::string &	contentType = ""
	)

Inserts the description of the file in GridFS collection.

Note that the stream will be reinitialized after the build call, so it will be possible to continue appending data to build another file.

Parameters

remoteName	filename to use for file stored in GridFS
contentType	optional MIME type for this object. (default is to omit)

Returns

the file object
