IOPartitionScheme
Abstract: The IOPartitionScheme class is the common base class for all partition scheme
objects.
The IOPartitionScheme class is the common base class for all partition scheme
objects. It extends the IOStorage class by implementing the appropriate open
and close semantics for partition objects (standard semantics are to act as a
multiplexor for incoming opens, producing one outgoing open with the correct
access). It also implements the default read and write semantics, which pass
all reads and writes through to the provider media unprocessed. For simple
schemes, the default behavior is sufficient. More complex partition schemes
such as RAID will want to do extra processing for reads and writes.
