DECODERS
|
|
Decoders are generally declared in groups of three functions
|
|
- An Open/Seek routine to prepare for reading
|
|
- A Read routine to move the actual data
|
|
- A Flush/Close routine to clean up
|
|
|
|
Three types of decoder currently exist
|
|
- In Place Decoders : operate on a buffer in place
|
|
- Buffered Decoders : require a temporary work buffer
|
|
- Buffer Loaders : read buffers from disk etc.
