Detailed Description

Handles the TKE_Open_Segment opcode.

TK_Open_Segment provides support for writing/reading the TKE_Open_Segment opcode object to/from an HSF file.

The nodes in the HOOPS/3dGS scene-graph are called 'segments' which store, geometry, attributes, and subsegments. After a HOOPS segment is open, geometry which should reside in that segment should be exported. Similarly, any attributes which need to affect the geometry in that segment should be exported.

This should be matched with a TKE_Close_Segment opcode object.

Member Function Documentation

char alter* TK_Open_Segment::GetSegment void   )  [inline]
 

Get the segment name buffer. Returns a pointer to the current segment name buffer which may then be modified directly

Definition at line 958 of file BOpcodeHandler.h.

char const* TK_Open_Segment::GetSegment void   )  const [inline]
 

Get the segment name. Returns a pointer to the current segment name

Definition at line 953 of file BOpcodeHandler.h.

TK_Status TK_Open_Segment::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.

void TK_Open_Segment::Reset void   )  [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_Open_Segment::SetSegment int  length  )  [inline]
 

Set the segment name. Makes sure the buffer is big enough to hold a string of 'length' characters

Definition at line 948 of file BOpcodeHandler.h.

void TK_Open_Segment::SetSegment char const *  segment  )  [inline]
 

Set the segment name. Makes sure the buffer is big enough to hold the segment name, and copies it in

Definition at line 942 of file BOpcodeHandler.h.

TK_Status TK_Open_Segment::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.
