## Detailed Description

class TK_Header : public BBaseOpcodeHandler

  Utility class for managing HSF header information.

  TK_Header does not explicitly handle any opcodes, but rather serves as a utility class for writing header information to an HSF file. It will dynamically create TK_Comment and TK_File_Info opcode handlers (which in turn export TKE_Comment and TKE_File_Info opcode objects)

  Public Functions

  inline TK_Header()

    constructor

  ~TK_Header()
  virtual TK_Status Read(BStreamFileToolkit &tk)

    Reads data from the toolkit buffer, decodes/decompresses it, and maps it to the opcode handlers data members. User-defined classes which need to write out custom data should utilize one of the available GetData() methods.

    Parameters

      tk – A reference to the BStreamFileToolkit object.

    Returns

      The result of the function call.

  virtual TK_Status Write(BStreamFileToolkit &tk)

    Encodes/compresses data and writes data to the toolkit buffer. User-defined classes which need to write out custom data should utilize one of the available PutData() methods, and first write out the opcode associated with the group of binary data followed by the data itself.

    Parameters

      tk – A reference to the BStreamFileToolkit object.

    Returns

      The result of the function call.

  TK_Status ReadAscii(BStreamFileToolkit &tk)

    Deprecated.

  TK_Status WriteAscii(BStreamFileToolkit &tk)

    Deprecated.

  virtual void Reset()

    Resets the current opcode handler. This is called by the toolkit when it is done processing an opcode. This method reinitializes any opcode handler variables and frees up temporary data.
