/**
|
|
* nsIRandomAccessStream
|
|
*
|
|
* An interface which supports both reading and writing to a storage starting
|
|
* at the current offset. Both the input stream and the output stream share the
|
|
* offset in the stream. Read operations invoked on the input stream start at
|
|
* the offset and advance it past the bytes read. Write operations invoked on
|
|
* the output stream start the offset and advance it past the bytes written.
|
|
* The offset can be set to an arbitrary value prior reading or writting. Each
|
|
* call to getInputStream or getOutputStream always returns the same object,
|
|
* rather than creating a new stream. It's recommended for objects implementing
|
|
* this interface to also implement nsIInputStream and nsIOutputStream, so they
|
|
* can be easilly used with e.g. NS_AsyncCopy.
