class Geo IffWriter
class Geo::IffWriter
└>Geo::IGeoStream
└>Geo::IGeoInputStream
An IffWriter allows you to use an IGeoStream to create Iff format binary files easily.
It is passed an IGeoStream in its constructor and also implements IGeoStream, thus making it like an Adaptor pattern. Although the class uses the terms 'BeginFile' and 'EndFile' the underlying stream can be of any type.
Functions
Name | Description |
---|---|
~IffWriter() | Note: Does not close the underlying IGeoStream (so you can write multiple Iff files to one IGeoStream) |
~IGeoInputStream() | Deleting a stream should behave like a close operation. |
~IGeoStream() | Deleting a stream should behave like a close operation. |
BeginChunk(u32) | Begin a new Iff chunk. |
BeginFile(u32, s32) | Write the Iff preamble and leave space to go back and fill in block data sizes, etc. |
BeginType(TypeId, u32) | Provide information about the typed data written to the stream. |
EndChunk() | Close the most recent chunk (note that the position of the stream when this is called determines the size of the chunk, be careful when jumping around inside IffWriter not to leave your current chunk) |
EndFile() | Close all open chunks, going back and filling in the chunk sizes before this point. |
EndType(u32) | Provide information about the typed data written to the stream. |
Fail() | Put the writer directly into a fail state. |
GetPosition() | Wrap the IGeoStream::GetPosition function. |
GetPosition() | Return the position of the read/write pointer within the stream (prototype matches ftell) |
GetPosition() | Return the position of the read/write pointer within the stream (prototype matches ftell) |
IffWriter(IGeoStream &) | Construct an IffWriter with a pre-existing IGeoStream. |
IsEof() | Is the read pointer at the end of the file (as with feof, only returns true if you have read past end) |
IsEof() | Is the read/write pointer at the end of the file (as with feof, only returns true if you have read past end) |
