## ◆ decode()

static XMLByte * Base64::decode | ( | const XMLByte *const | inputData,
|  | XMLSize_t * | decodedLength,
|  | MemoryManager *const | memMgr = 0,
|  | Conformance | conform = Conf_RFC2045 )
| static

Decodes Base64 data into octets.

NOTE: The returned buffer is dynamically allocated and is the responsibility of the caller to delete it when not longer needed. Use the memory manager to release the returned buffer or operator delete() if none was provided.

Parameters

  inputData | Base64 data in XMLByte stream.
  decodedLength | Length of decoded XMLByte stream.
  memMgr | client provided memory manager
  conform | conformance specified: if the input data conforms to the RFC 2045 it is allowed to have any number of whitespace characters inside; if it conforms to the XMLSchema specs, it is allowed to have at most one whitespace character between the quartets

Returns
  Decoded binary data in XMLByte stream, or NULL if input data can not be decoded.

## ◆ decodeToXMLByte()

static XMLByte * Base64::decodeToXMLByte | ( | const XMLCh *const | inputData,
|  | XMLSize_t * | decodedLength,
|  | MemoryManager *const | memMgr = 0,
|  | Conformance | conform = Conf_RFC2045 )
| static

Decodes Base64 data into octets.

NOTE: The returned buffer is dynamically allocated and is the responsibility of the caller to delete it when not longer needed. Use the memory manager to release the returned buffer or operator delete() if none was provided.

Parameters

  inputData | Base64 data in XMLCh stream.
  decodedLength | Length of decoded XMLByte stream.
  memMgr | client provided memory manager
  conform | conformance specified: if the input data conforms to the RFC 2045 it is allowed to have any number of whitespace characters inside; if it conforms to the XMLSchema specs, it is allowed to have at most one whitespace character between the quartets

Returns
  Decoded binary data in XMLByte stream, or NULL if input data can not be decoded.

## ◆ encode()

static XMLByte * Base64::encode | ( | const XMLByte *const | inputData,
|  | const XMLSize_t | inputLength,
|  | XMLSize_t * | outputLength,
|  | MemoryManager *const | memMgr = 0 )
| static

Encodes octets into Base64 data.

NOTE: The returned buffer is dynamically allocated and is the responsibility of the caller to delete it when not longer needed. Use the memory manager to release the returned buffer or operator delete() if none was provided.

Parameters

  inputData | Binary data in XMLByte stream.
  inputLength | Length of the XMLByte stream.
  outputLength | Length of the encoded Base64 byte stream.
  memMgr | client provided memory manager

Returns
  Encoded Base64 data in XMLByte stream, or NULL if input data can not be encoded.

## ◆ getCanonicalRepresentation()

static XMLCh * Base64::getCanonicalRepresentation | ( | const XMLCh *const | inputData,
|  | MemoryManager *const | memMgr = 0,
|  | Conformance | conform = Conf_RFC2045 )
| static

get canonical representation

Caller is responsible for the proper deallocation of the string returned.

Parameters

  inputData | A string containing the Base64
  memMgr | client provided memory manager
  conform | conformance specified

return: the canonical representation of the Base64 if it is a valid Base64 0 otherwise

## ◆ getDataLength()

static int Base64::getDataLength | ( | const XMLCh *const | inputData,
|  | MemoryManager *const | memMgr = 0,
|  | Conformance | conform = Conf_RFC2045 )
| static

Get data length.

Returns length of decoded data given an array containing encoded data.

Parameters

  inputData | Base64 data in XMLCh stream.
  memMgr | client provided memory manager
  conform | conformance specified

Returns
  Length of decoded data, or -1 if input data can not be decoded.
