Member Function Documentation

virtual EState GetState ( ) [pure virtual]

Search for all occurrences

Query the current state of the stream.

virtual bool Open ( void * pStreamData ) [pure virtual]

Search for all occurrences

Open the stream.

Returns:: True if successful.

virtual bool Close ( ) [pure virtual]

Search for all occurrences

Close the stream.

Returns:: True if successful.

virtual bool Flush ( ) [pure virtual]

Search for all occurrences

Empties the internal data of the stream.

Returns:: True if successful.

virtual int Write	(	const void *	,
		int
	)		`[pure virtual]`

Search for all occurrences

Writes a memory block.

Parameters:

pData	Pointer to the memory block to write.
pSize	Size (in bytes) of the memory block to write.

Returns:: The number of bytes written in the stream.

virtual int Read	(	void *	,
		int
	)		const `[pure virtual]`

Search for all occurrences

Read bytes from the stream and store them in the memory block.

Parameters:

pData	Pointer to the memory block where the read bytes are stored.
pSize	Number of bytes read from the stream.

Returns:: The actual number of bytes successfully read from the stream.

virtual char* ReadString	(	char *	pBuffer,
		int	pMaxSize,
		bool	pStopAtFirstWhiteSpace = `false`
	)		`[virtual]`

Search for all occurrences

Read a string from the stream.

The default implementation is written in terms of Read() but does not cope with DOS line endings. Subclasses may need to override this if DOS line endings are to be supported.

Parameters:

pData	Pointer to the memory block where the read bytes are stored.
pMaxSize	Maximum number of bytes to be read from the stream.
pStopAtFirstWhiteSpace	Stop reading when any whitespace is encountered. Otherwise read to end of line (like fgets()).

Returns:: pBuffer, if successful, else NULL.

virtual int GetReaderID ( ) const [pure virtual]

Search for all occurrences

If not specified by KFbxImporter::Initialize(), the importer will ask the stream to select an appropriate reader ID to associate with the stream.

KFbxIOPluginRegistry can be used to locate id by extension or description. Return -1 to allow FBX to select an appropriate default.

virtual int GetWriterID ( ) const [pure virtual]

Search for all occurrences

If not specified by KFbxExporter::Initialize(), the exporter will ask the stream to select an appropriate writer ID to associate with the stream.

KFbxIOPluginRegistry can be used to locate id by extension or description. Return -1 to allow FBX to select an appropriate default.

virtual void Seek	(	const FbxInt64 &	pOffset,
		const FbxFile::ESeekPos &	pSeekPos
	)		`[pure virtual]`

Search for all occurrences

Adjust the current stream position.

Parameters:

pSeekPos	Pre-defined position where offset is added (FbxFile::eBegin, FbxFile::eCurrent:, FbxFile::eEnd)
pOffset	Number of bytes to offset from pSeekPos.
