All Implemented Interfaces:

Closeable, AutoCloseable

public class AwsUnsignedChunkedDecodingChecksumInputStream
extends AbstractAwsInputStream

Merges chunks from AWS chunked AwsUnsignedChunkedEncodingInputStream. The checksum is optionally included in the stream as part of the "trail headers" after the last chunk.

The original stream looks like this:

 24
 ## sample test file ##

 demo=content
 0
 x-amz-checksum-sha256:1VcEifAruhjVvjzul4sC0B1EmlUdzqvsp6BP0KSVdTE=
 

The format of each chunk of data is:

 [hex-encoded-number-of-bytes-in-chunk][EOL]
 [payload-bytes-of-this-chunk][EOL]
 

The format of the full payload is:

 [hex-encoded-number-of-bytes-in-chunk][EOL]
 [payload-bytes-of-this-chunk][EOL]
 0[EOL]
 x-amz-checksum-[checksum-algoritm]:[checksum][EOL]
 [other trail headers]
