Method Detail

builder

public static AwsUnsignedChunkedEncodingInputStream.Builder builder()

calculateChecksumContentLength

public static long calculateChecksumContentLength(Algorithm algorithm,
                                                  String headerName)

Calculates the content length for a given Algorithm and header name.

Parameters:

algorithm - Algorithm used.

headerName - Header name.

Returns:

Content length of the trailer that will be appended at the end.

calculateStreamContentLength

public static long calculateStreamContentLength(long originalLength,
                                                long defaultChunkSize)

createFinalChunk

protected byte[] createFinalChunk(byte[] finalChunk)

Description copied from class: AwsChunkedEncodingInputStream

The final chunk.

Specified by:

createFinalChunk in class AwsChunkedEncodingInputStream

Parameters:

finalChunk - The last byte which will be often 0 byte.

Returns:

Final chunk that will be appended with CRLF or any required signatures.

createChunk

protected byte[] createChunk(byte[] chunkData)

Description copied from class: AwsChunkedEncodingInputStream

Creates chunk for the given buffer. The chucks could be appended with Signatures or any additional bytes by Concrete classes.

Specified by:

createChunk in class AwsChunkedEncodingInputStream

Parameters:

chunkData - The chunk of original data.

Returns:

Chunked data which will have signature if signed or just data if unsigned.

createChecksumChunkHeader

protected byte[] createChecksumChunkHeader()

Specified by:

createChecksumChunkHeader in class AwsChunkedEncodingInputStream

Returns:

ChecksumChunkHeader in bytes based on the Header name field.
