+/**
+ * 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.
