Protected Attributes

BBaseOpcodeHandlerm_parts [16]
 Array of simple contitional action handlers which together represent the full specification.


Detailed Description

entire conditional actions setting will be interpreted into the composite pseudo-object, which will contain one or more simple objects which can actually be written. reading will just interpret the simple objects directly, as usual

Member Function Documentation

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

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.

Reimplemented from BBaseOpcodeHandler.

TK_Status HTK_Conditional_Actions::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:
tk A reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

TK_Status HTK_Conditional_Actions::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:
tk A reference to the BStreamFileToolkit object.
key An identifier to the object (for example, the HOOPS key of a geometry item)
special A string value of particular data
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

References BBaseOpcodeHandler::Interpret().

TK_Status HTK_Conditional_Actions::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:
tk A reference to the BStreamFileToolkit object.
key An identifier to the object (for example, the HOOPS key of a geometry item)
variant optional specification of an alternate form, such as a Level-of-Detail representation
Returns:
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

TK_Status HTK_Conditional_Actions::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:
tk A reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Implements BBaseOpcodeHandler.

TK_Status HTK_Conditional_Actions::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:
tk A reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Implements BBaseOpcodeHandler.
