Detailed Description

Handles the TKE_Start_Compression and TKE_Stop_Compression opcodes.

TK_Compression provides support for writing/reading the TKE_Start_Compression and TKE_Stop_Compression opcode object to/from an HSF file.

The TKE_Start_Compression and TKE_Stop_Compression opcode objects denote the beginning and end of global file compression.

Member Function Documentation

TK_Status TK_Compression::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_Compression::Interpret ( BStreamFileToolkit tk,
ID_Key  key,
int  variant 
) [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_Compression::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_Compression::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_Compression::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.
