Method Detail

calculateChunkLength

public static long calculateChunkLength(long originalContentLength)

Parameters:

originalContentLength - Original Content length.

Returns:

Calculates Chunk Length.

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.

createChecksumTrailer

public static ByteBuffer createChecksumTrailer(String computedChecksum,
                                               String trailerHeader)

Creates Chunk encoded checksum trailer for a computedChecksum which is in Base64 encoded.

Parameters:

computedChecksum - Base64 encoded computed checksum.

trailerHeader - Header for the checksum data in the trailer.

Returns:

Chunk encoded checksum trailer with given header.

createChunk

public static ByteBuffer createChunk(ByteBuffer chunkData,
                                     boolean isLastByte)

Creates ChunkEncoded data for an given chunk data.

Parameters:

chunkData - chunk data that needs to be converted to chunk encoded format.

isLastByte - if true then additional CRLF will not be appended.

Returns:

Chunk encoded format of a given data.
