Examples of com.amazonaws.internal.ResettableInputStream

com.amazonaws.internal.ResettableInputStream
A mark-and-resettable input stream that can be used on files or file input streams. In particular, a {@link ResettableInputStream} allows the close operation tobe disabled via {@link #disableClose()} (to avoid accidentally being closed).This is necessary when such input stream needs to be marked-and-reset multiple times but only as long as the stream has not been closed.
The creator of this input stream should therefore always call {@link #release()} in a finally block to truly release the underlyingresources. @see Releasable
