Detailed Description

Loading and Saving Plug-in Data, Guidelines for Handling Character Strings, Class ILoad, Class ClassDesc, Class ClassDirectory, Class Interface.

Description:

This class provides methods to save data to disk.

Note: It is not valid to write two CStrs in the same chunk of a 3ds Max file, since ILoad::ReadCStringChunk() sets the size for the string to the ChunkSize. However it is possible to write other data, such as two ints, into the same chunk.

Note about member alignment: Please make sure that when you save data from your plugin you save individual data members using a chunk ID instead of saving the image of a class. Saving (and loading) a class image puts you at risk of running into member alignment problems and as such could potentially corrupt saved files. File IO would be put further at risk when you keep Intel's IA-64 architecture in mind which depends on member alignment. What you should not do is outlined in the following example when loading a class image; iload->Read(&myclass, sizeof(MyClass), &ab);

Once you change the class in such a way that it affects the data size you run the risk of having to support different versions, file IO incompatibility, and member alignment issues.

The following global function is not part of this class but is available for use:

Member Function Documentation

GetRefID()

virtual int GetRefID ( void *  ptarg )

pure virtual

Remarks

This method is not normally used because the reference hierarchy is saved automatically. In certain cases however this method is quite useful. This method is used in saving a pointer to some object (or a table of pointers). This is a pointer to one of the objects that the scene saves with the reference hierarchy, but it is not a pointer that itself is a reference.

Parameters

ptarg

The pointer to save.

Returns

The id that may be saved to disk.

BeginChunk()

virtual void BeginChunk ( USHORT  id )

pure virtual

Remarks

This method is used to begin a chunk. The ID passed need only be unique within the plug-ins data itself.

Parameters

id	The id for the chunk.

EndChunk()

virtual void EndChunk ( )

pure virtual

Remarks

This method is used to end a chunk, and back-patch the length.

CurChunkDepth()

virtual int CurChunkDepth ( )

pure virtual

Remarks

This method is used internally for checking balanced BeginChunk/EndChunk.

WriteVoid()

IOResult WriteVoid ( const void *  buf, ULONG  nbytes, ULONG *  nwrit  )

inline

Remarks

This method writes a block of bytes to the output stream.

Parameters

buf	The buffer to write.
nbytes	The number of bytes to write.
nwrit	The number of bytes actually written.

Returns

IO_OK - The write was acceptable - no errors.

IO_ERROR - This is returned if an error occurred. Note that the plug-in should not put up a message box if a write error occurs. It should simply return the error status. This prevents a overabundance of messages from appearing.

WriteWString() [1/2]

virtual IOResult WriteWString ( const char *  str )

pure virtual

Remarks

This method is used to write wide character strings.

Parameters

str	The string to write. The string must be ACP encoded.

Returns

IO_OK - The write was acceptable - no errors.

IO_ERROR - This is returned if an error occurred.

WriteWString() [2/2]

virtual IOResult WriteWString ( const wchar_t *  str )

pure virtual

Remarks

This method is used to write wide character strings.

Parameters

str	The string to write.

Returns

IO_OK - The write was acceptable - no errors.

IO_ERROR - This is returned if an error occurred.

WriteCString() [1/2]

virtual IOResult WriteCString ( const char *  str )

pure virtual

Remarks

This method is used to write single byte character strings.

Parameters

str	The string to write. The string must be ACP encoded.

Returns

IO_OK - The write was acceptable - no errors.

IO_ERROR - This is returned if an error occurred.

WriteCString() [2/2]

virtual IOResult WriteCString ( const wchar_t *  str )

pure virtual

Remarks

This method is used to write single byte character strings.

Parameters

str	The string to write.

Returns

IO_OK - The write was acceptable - no errors.

IO_ERROR - This is returned if an error occurred.

DoingWhat()

virtual FileIOType DoingWhat ( )

pure virtual

Remarks

Determines if we are saving a standard 3ds Max file (.MAX) or a material library (.MAT).

Returns

One of the following values:

IOTYPE_MAX

IOTYPE_MATLIB

SavingVersion()

virtual DWORD SavingVersion ( ) const

inlinevirtual

Remarks

This method returns a value to indicate the current version of the file being saved. It returns 0 for the current version, MAX_RELEASE_R12 for 3ds Max 2010, etc. Call this method to determine the format in which to save the data.

• Adding a new chunk (unknown to the previous version) should be fine. Plug-ins should be written to skip over unknown chunks.
• Removing a chunk is not fine. Never delete a chunk id. Plug-ins need to be prepared to save out the data corresponding to the old chunk id when this method returns the version of a previous 3ds Max release.
• Changing the contents of an existent chunk is not fine, since it can break file compatibility. Add a new chunk to store the modified data structure, and keep the code that loads the old chunk. Be prepared to convert the old data to the new format if that makes sense.
