invalidate();
Invalidate the cache.
RWBoolean
read(RWoffset locn, void* dat);
Return the data located at offset locn of the associated RWFile. The data is put in the
buffer pointed to by dat. This buffer must be at least as long as the block size specified
when the cache was constructed. Returns TRUE if the operation was successful,
otherwise FALSE.
RWBoolean
write(RWoffset locn, void* dat);
Write the block of data pointed to by dat to the offset locn of the associated RWFile. The
number of bytes written is given by the block size specified when the cache was
constructed. The actual write to disk may be deferred. Use member function flush() to
perform any pending output. Returns TRUE if the operation was successful, otherwise
FALSE.
