Detailed Description
-
class TK_Renumber : public BBaseOpcodeHandler
Handles the TKE_Renumber_Key_Global, TKE_Renumber_Key_Local, and TKE_Priority opcodes.
TK_Renumber provides support for writing/reading the TKE_Renumber_Key_Global and TKE_Renumber_Key_Local opcode objects to/from an HSF file. This action operates on whatever entity was specified in the previous opcode.
The HOOPS/3dGS scene-graph supports the concept of renumbered keys. (Keys can refer to either segments or geometric primitives.) HOOPS entities that do not have keys (e.g. rendering options and other attributes) may not be renumbered. HOOPS/3DGS segments may hav a priority value assigned which overrides the default alphabetic sorting.
Public Functions
-
inline TK_Renumber(unsigned char opcode, long key = 0)
same as the default constructor in BBaseOpcodeHandler, except that a new key can optionally be provided directly at the time of construction
-
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.
-
inline void SetKey(long k)
Sets the key (identifier) value
-
inline long GetKey() const
Returns the key (identifier) value
-
inline TK_Renumber(unsigned char opcode, long key = 0)
