bool LLMimeParser::Impl::eatCRLF ( std::istream & istr ) [protected]

Eat CRLF.

This method has no concept of the limit, so ensure you have at least 2 characters left to eat before hitting the limit. This method will increment mScanCount as it goes.

Parameters:

istr

The input stream.

Returns:: Returns true if CRLF was found and consumed off of istr.

std::string LLMimeParser::Impl::findSeparator ( std::string multipart_content_type ) [protected]

Figure out the separator string from a content type header.

Parameters:

multipart_content_type

The content type value from the headers.

Returns:: Returns the separator string.

bool LLMimeParser::Impl::parseHeaders	(	std::istream &	istr,
		S32	limit,
		LLSD &	headers
	)			`[protected]`

parse the headers.

At the end of a successful parse, mScanCount will be at the start of the content.

Parameters:

	istr	The input stream.
	limit	maximum number of bytes to process
	headers[out]	A map of the headers found.

Returns:: Returns true if the parse was successful.

bool LLMimeParser::Impl::parseIndex	(	std::istream &	istr,
		S32	limit,
		const std::string &	separator,
		bool	is_subpart,
		LLMimeIndex &	index
	)

Parse a mime entity to find the index information.

This method will scan the istr until a single complete mime entity is read, an EOF, or limit bytes have been scanned. The istr will be modified by this parsing, so pass in a temporary stream or rewind/reset the stream after this call.

Parameters:

	istr	An istream which contains a mime entity.
	limit	The maximum number of bytes to scan.
	separator	The multipart separator if it is known.
	is_subpart	Set true if parsing a multipart sub part.
	index[out]	The parsed output.
