Detailed Description

Handles the TKE_Tag opcode.

Tags are a means of instructing the toolkit that an object should be 'recorded' during file import and/or export. Things that may be revisited later for refinement should be tagged. See the Programming Guide for more detailed information.

Member Function Documentation

TK_Status TK_Tag::Execute ( BStreamFileToolkit tk) [virtual]

Processes the binary data that has been read for the current object, which involves passing the data to application-specific data structures.

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

Reimplemented from BBaseOpcodeHandler.

TK_Status TK_Tag::Interpret ( BStreamFileToolkit tk,
ID_Key  key,
int  variant = 0 
) [virtual]

Extracts graphics data (typically from the application's scene-graph) and maps it to the opcode handler's data members in preparation for writing out an object to the file.

Parameters:
tkA reference to the BStreamFileToolkit object.
keyAn identifier to the object (for example, the HOOPS key of a geometry item)
variantoptional specification of an alternate form, such as a Level-of-Detail representation
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

TK_Status TK_Tag::Interpret ( BStreamFileToolkit tk,
ID_Key  key,
char const *  special 
) [inline, virtual]

Extracts graphics data (typically from the application's scene-graph) and maps it to the opcode handler's data members in preparation for writing out an object to the file.

Parameters:
tkA reference to the BStreamFileToolkit object.
keyAn identifier to the object (for example, the HOOPS key of a geometry item)
specialA string value of particular data
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

References BBaseOpcodeHandler::Interpret().

TK_Status TK_Tag::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.

TK_Status TK_Tag::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.
