Detailed Description

Handles the TKE_Glyph_Definition opcode.

TK_Glyph_Definition provides support for writing/reading the TKE_Glyph_Definition opcode object to/from an HSF file.

The HOOPS/3dGS scene-graph supports 'glyph definitions', which define how to draw markers and components of line patterns.

constructor


Member Function Documentation

TK_Status TK_Glyph_Definition::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.

Reimplemented in HTK_Glyph_Definition.

char const* TK_Glyph_Definition::GetDefinition ( ) const [inline]

Returns the definition buffer

char* TK_Glyph_Definition::GetDefinition ( ) [inline]

Returns the definition buffer, which can be modified directly

int TK_Glyph_Definition::GetDefinitionSize ( ) const [inline]

Returns the definition size

char const* TK_Glyph_Definition::GetName ( ) const [inline]

Returns the glyph name

char* TK_Glyph_Definition::GetName ( ) [inline]

Returns the glyph name buffer, which can be modified directly

TK_Status TK_Glyph_Definition::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.

void TK_Glyph_Definition::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.

void TK_Glyph_Definition::SetDefinition ( int  size,
char const *  data = 0 
)

Sets the definition. Allocates the buffer and copies the data if provided

void TK_Glyph_Definition::SetName ( char const *  name)

Sets the glyph name. Allocates the buffer and copies the name string

void TK_Glyph_Definition::SetName ( int  length)

Sets the glyph name buffer. Allocates a buffer large enough to hold a string of 'length' characters

TK_Status TK_Glyph_Definition::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.
