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 )  [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. Returns: Encoded Base64 data in byte stream or NULL if input data cannot be encoded.

void ACE_Base64::init (    )  [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.
