Detailed Description

Handles the TKE_User_Options opcode.

TK_User_Options provides support for writing/reading the TKE_User_Options opcode object to/from an HSF file.

The HOOPS/3dGS scene-graph supports storing non-graphical data per segment. A user-option is simply a string containing a comma-separated set of string pairs.

constructor


Member Function Documentation

TK_Status TK_User_Options::Clone ( BStreamFileToolkit tk,
BBaseOpcodeHandler **  handler 
) const [virtual]

Copies the opcode handler

Parameters:
tkA reference to the BStreamFileToolkit object.
handlerA pointer to the opcode handler object. Passed by reference.
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

Reimplemented in HTK_User_Options.

int TK_User_Options::GetLength ( ) [inline]

Returns the size of the string buffer (number of chars, not including any space for trailing null)

char const* TK_User_Options::GetOptions ( ) const [inline]

Returns the user options string.

char* TK_User_Options::GetOptions ( ) [inline]

Returns the user options string buffer, which may be modified directly

TK_Status TK_User_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.

Parameters:
tkA reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Implements BBaseOpcodeHandler.

void TK_User_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_User_Options::SetOptions ( char const *  options) [inline]

Sets the user options string. Allocates the buffer and copies the string

void TK_User_Options::SetOptions ( int  length) [inline]

Sets the user options string buffer. Allocates a buffer which can hold a srting of 'length' characters

TK_Status TK_User_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.

Parameters:
tkA reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Implements BBaseOpcodeHandler.
