  • LengthCheckInputStream

    public LengthCheckInputStream(InputStream in,
     long expectedLength,
     boolean includeSkipped)

    Constructs an input stream that performs length check to ensure the number of bytes read from the underlying input stream is the same as the expected total.

    Parameters:

    in - the underlying input stream

    expectedLength - the total length of the data in bytes expected to be read from the underlying input stream; must be non-negative.

    includeSkipped - true if bytes skipped are to be considered as part of the data length; false otherwise. Typically, this parameter should be set to false for uploading data to AWS, but set to true for receiving data from AWS.
