Handles the TKE_Unicode_Options opcode.
TK_User_Options provides support for writing/reading the TKE_Unicode_Options opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph supports storing non-graphical data per segment. A unicode-option is simply a wide character (2-bytes per character) string containing a comma-separated set of string pairs.
TK_Unicode_Options::TK_Unicode_Options | ( | ) | [inline] |
constructor
TK_Status TK_Unicode_Options::Clone | ( | BStreamFileToolkit & | tk, |
BBaseOpcodeHandler ** | handler | ||
) | const [virtual] |
Copies the opcode handler
tk | A reference to the BStreamFileToolkit object. |
handler | A pointer to the opcode handler object. Passed by reference. |
Reimplemented from BBaseOpcodeHandler.
Reimplemented in HTK_Unicode_Options.
int TK_Unicode_Options::GetLength | ( | ) | [inline] |
Returns the size of the string buffer (number of shorts, not including any space for trailing null)
unsigned short const* TK_Unicode_Options::GetOptions | ( | ) | const [inline] |
Returns the user options string.
unsigned short* TK_Unicode_Options::GetOptions | ( | ) | [inline] |
Returns the user options string buffer, which may be modified directly
TK_Status TK_Unicode_Options::Read | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
void TK_Unicode_Options::Reset | ( | ) | [virtual] |
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.
Reimplemented from BBaseOpcodeHandler.
void TK_Unicode_Options::SetOptions | ( | unsigned short const * | options | ) |
Sets the user options string. Allocates the buffer and copies the string
void TK_Unicode_Options::SetOptions | ( | int | length | ) |
Sets the user options string buffer. Allocates a buffer which can hold a srting of 'length' characters
TK_Status TK_Unicode_Options::Write | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
int TK_Unicode_Options::m_length [protected] |
Length of text string
unsigned short* TK_Unicode_Options::m_string [protected] |
Text string
