Detailed Description

Encode/Decode a stream of bytes according to Base64 encoding.

This class provides methods to encode or decode a stream of bytes to/from Base64 encoding. It doesn't convert the input stream to a canonical form before encoding.

Member Function Documentation

ACE_Byte * ACE_Base64::decode	(	const ACE_Byte *	input,
		size_t *	output_len
	)		[static]

Decodes a stream of Base64 to bytes data

Parameters:

input	Encoded Base64 data in byte stream.
output_len	Length of the binary byte stream.

Returns:

Binary data in byte stream or NULL if input data cannot be encoded.

ACE_Byte * ACE_Base64::encode	(	const ACE_Byte *	input,
		const size_t	input_len,
		size_t *	output_len,
		bool	is_chunked = true
	)		[static]

Encodes a stream of bytes to Base64 data

Parameters:

input	Binary data in byte stream.
input_len	Length of the byte stream.
output_len	Length of the encoded Base64 byte stream.
is_chunked	If true, terminate 72 character blocks with newline

Returns:

Encoded Base64 data in byte stream or NULL if input data cannot be encoded.

void ACE_Base64::init

(

void

)

[static, private]

Initialize the tables for encoding/decoding.

size_t ACE_Base64::length

(

const ACE_Byte *

input

)

[static]

Return the length of the encoded input data

Parameters:

input

Encoded Base64 data in byte stream.

Returns:

Length of the encoded Base64 data.

Member Data Documentation

ACE_Byte ACE_Base64::decoder_ [static, private]

Alphabet used for decoding i.e decoder_[alphabet_[i = 0..63]] = i.

bool ACE_Base64::init_ = false [static, private]

Boolean to denote whether initialization is complete.

ACE_Byte ACE_Base64::member_ [static, private]

Alphabet used to check valid range of encoded input i.e member_[alphabet_[0..63]] = 1
