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:
inputEncoded Base64 data in byte stream.
output_lenLength 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:
inputBinary data in byte stream.
input_lenLength of the byte stream.
output_lenLength of the encoded Base64 byte stream.
is_chunkedIf 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:
inputEncoded Base64 data in byte stream.
Returns:
Length of the encoded Base64 data.
ACE_Base64& ACE_Base64::operator= ( ACE_Base64 const &  ) [private]

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
