Detailed Description

Handles the TKE_Start_User_Data opcode.

The HOOPS Stream File can contain user-data, which is denoted by TKE_Start_User_Data. TK_User_Data will handle the TKE_Start_User_Data opcode by simply reading the data, and not doing anything with it. Therefore, this class must be overloaded in order to both import (and handle), as well as export user-data.

To ensure that user data will be gracefully handled (skipped-over) by non-custom handlers (meaning, an application that is using the default toolkit and doesn't understand the custom user data), custom user data must be written out by exporting the following elements in order:

1.  the TKE_Start_User_Data opcode
2.  the number of bytes of user data that will follow
3.  the user data itself
4.  the TKE_Stop_User_Data_Opcode

See the HOOPS/Stream Programming Guide for more detailed information about how to handle user data and create custom files.

inline

constructor

Member Function Documentation

◆ Clone()

TK_Status TK_User_Data::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.

◆ Execute()

TK_Status TK_User_Data::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.

◆ GetSize()

int TK_User_Data::GetSize ( ) const
inline

Returns the size of the data buffer

◆ GetUserData() [1/2]

unsigned char const* TK_User_Data::GetUserData ( ) const
inline

Returns the address of the data buffer

◆ GetUserData() [2/2]

unsigned char* TK_User_Data::GetUserData ( )
inline

Returns the address of the data buffer, which may be modified directly

◆ Read()

TK_Status TK_User_Data::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.

◆ Reset()

void TK_User_Data::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.

◆ Resize()

void TK_User_Data::Resize ( int  size)

Change the size of the data buffer

◆ set_data()

void TK_User_Data::set_data ( int  size,
unsigned char const *  bytes = 0 
)
protected

internal use

for internal use only

◆ SetSize()

void TK_User_Data::SetSize ( int  size)

Sets the size of the data buffer.

◆ SetUserData()

void TK_User_Data::SetUserData ( int  size,
unsigned char const *  bytes = 0 
)
inline

Sets the data buffer. Allocates a buffer which can hold 'size' bytes and, if specified, copies 'bytes' into the buffer

◆ Write()

TK_Status TK_User_Data::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.
