## Detailed Description

class `TK_Grid` : public BBaseOpcodeHandler

  Handles the TKE_Grid opcode.

  TK_Grid provides support for writing/reading the TKE_Grid opcode object to/from an HSF file.

  The HOOPS/3dGS scene-graph supports ‘grid’ primitives which are defined by a grid type, origin, and points which define grid spacing.

  Public Functions

  inline `TK_Grid`()

    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.

  virtual TK_Status `Clone`(BStreamFileToolkit &tk, BBaseOpcodeHandler **handler) const

    Copies the opcode handler

    Parameters: | tk – A reference to the BStreamFileToolkit object. handler – A pointer to the opcode handler object. Passed by reference.
    Returns: | The result of the function call.

  TK_Status `ReadAscii`(BStreamFileToolkit &tk)

    Deprecated.

  TK_Status `WriteAscii`(BStreamFileToolkit &tk)

    Deprecated.
