Nested Classes

Modifier and Type	Class	Description
static class	ChecksumUtil.ConstantChecksumAlgorithm	An implementation of a ChecksumAlgorithm that will map to ConstantChecksum, which provides a constant checksum.

Method Summary

Modifier and Type	Method	Description
static String	checksumHeaderName(ChecksumAlgorithm checksumAlgorithm)	Get the correct checksum header name based on the checksum-algorithm.
static SdkChecksum	fromChecksumAlgorithm(ChecksumAlgorithm checksumAlgorithm)	Gets the SdkChecksum object based on the given ChecksumAlgorithm.
static void	readAll(InputStream inputStream)	Read the entirety of an input-stream - this is useful when the stream has side-effects (such as calculating a checksum) when it gets read.

Method Details

checksumHeaderName

public static String checksumHeaderName(ChecksumAlgorithm checksumAlgorithm)

Get the correct checksum header name based on the checksum-algorithm. This is required to be of the form x-amz-checksum-*, where '*' is alphanumeric checksum-algorithm-id in lower-case form. Examples include:

x-amz-checksum-sha256, x-amz-checksum-sha1, x-amz-checksum-crc32, x-amz-checksum-crc32c, x-amz-checksum-md5

fromChecksumAlgorithm

public static SdkChecksum fromChecksumAlgorithm(ChecksumAlgorithm checksumAlgorithm)

Gets the SdkChecksum object based on the given ChecksumAlgorithm.

readAll

public static void readAll(InputStream inputStream)

Read the entirety of an input-stream - this is useful when the stream has side-effects (such as calculating a checksum) when it gets read.
