  namespace Poco {
  
  class Foundation_API HexBinaryEncoderBuf: public UnbufferedStreamBuf
This streambuf encodes all data written to it in hexBinary encoding and forwards it to a connected ostream. In hexBinary encoding, each binary octet is encoded as a character tuple, consisting of two hexadecimal digits ([0-9a-fA-F]) representing the octet code. See also: XML Schema Part 2: Datatypes (http://www.w3.org/TR/xmlschema-2/),

section 3.2.15.


{ public: HexBinaryEncoderBuf(std::ostream& ostr); ~HexBinaryEncoderBuf(); int close(); Closes the stream buffer. void setLineLength(int lineLength); Specify the line length. After the given number of characters have been written, a newline character will be written. Specify 0 for an unlimited line length. int getLineLength() const; Returns the currently set line length. void setUppercase(bool flag = true); Specify whether hex digits a-f are written in upper or lower case. private: int writeToDevice(char c);

  class Foundation_API HexBinaryEncoderIOS: public virtual std::ios
The base class for HexBinaryEncoder. This class is needed to ensure the correct initialization order of the stream buffer and base classes. { public: HexBinaryEncoderIOS(std::ostream& ostr); ~HexBinaryEncoderIOS(); int close(); HexBinaryEncoderBuf* rdbuf(); 

  protected:
          HexBinaryEncoderBuf _buf;
  };
  
  class Foundation_API HexBinaryEncoder: public HexBinaryEncoderIOS, public std::ostream
This ostream encodes all data written to it in BinHex encoding and forwards it to a connected ostream. Always call close() when done writing data, to ensure proper completion of the encoding operation. In hexBinary encoding, each binary octet is encoded as a character tuple, consisting of two hexadecimal digits ([0-9a-fA-F]) representing the octet code.
