## Detailed Description

class `TK_Tag` : public BBaseOpcodeHandler

  Handles the TKE_Tag opcode.

  Tags are a means of instructing the toolkit that an object should be ‘recorded’ during file import and/or export. Things that may be revisited later for refinement should be tagged. See the Programming Guide for more detailed information.

  Public Functions

  inline `TK_Tag`(unsigned char opcode = TKE_Tag)

    constructor

  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 TK_Status `Execute`(BStreamFileToolkit &tk)

    Processes the binary data that has been read for the current object, which involves passing the data to application-specific data structures.

    Parameters: | tk – A reference to the BStreamFileToolkit object.
    Returns: | The result of the function call.

  virtual TK_Status `Interpret`(BStreamFileToolkit &tk, long key, int variant = 0)

    Extracts graphics data (typically from the application’s scene-graph) and maps it to the opcode handler’s data members in preparation for writing out an object to the file.

    Parameters: | tk – A reference to the BStreamFileToolkit object. key – An identifier to the object (for example, the HOOPS key of a geometry item) variant – optional specification of an alternate form, such as a Level-of-Detail representation
    Returns: | The result of the function call.

  inline virtual TK_Status `Interpret`(BStreamFileToolkit &tk, long key, char const *special)

    Extracts graphics data (typically from the application’s scene-graph) and maps it to the opcode handler’s data members in preparation for writing out an object to the file.

    Parameters: | tk – A reference to the BStreamFileToolkit object. key – An identifier to the object (for example, the HOOPS key of a geometry item) special – A string value of particular data
    Returns: | The result of the function call.
