Detailed Description
-
class TK_Conditions : public BBaseOpcodeHandler
Handles the TKE_Conditions opcode.
TK_Conditions provides support for writing/reading the TKE_Conditions opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph supports conditional use of style & include segments. A condition is simply a string containing a comma-separated list of condition flags being turned on or off
Public Functions
-
inline TK_Conditions()
constructor
-
~TK_Conditions()
-
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.
-
void SetConditions(char const *options)
Sets the conditions string. Allocates the buffer and copies the string
-
void SetConditions(int length)
Sets the conditions string buffer. Allocates a buffer which can hold a srting of ‘length’ characters
-
inline char const *GetConditions() const
Returns the conditions string.
-
inline char *GetConditions()
Returns the conditions string buffer, which may be modified directly
-
inline int GetLength()
Returns the size of the string buffer (number of chars, not including any space for trailing null)
