Detailed Description

class TK_Circle : public BBaseOpcodeHandler

Handles the TKE_Circle, TKE_Circular_Arc, TKE_Circular_Chord and TKE_Circular_Wedge opcodes.

TK_Circle provides support for writing/reading the TKE_Circle, TKE_Circular_Arc, TKE_Circular_Chord and TKE_Circular_Wedge opcode objects to/from an HSF file.

The HOOPS/3dGS scene-graph can contain various forms of a ‘circle’ primitive, defined by three non-colinear points.

Public Functions

inline TK_Circle(unsigned char opcode): 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.

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.
