Method Details

getObjectChecksumEnabledPerRequest

public static boolean getObjectChecksumEnabledPerRequest(SdkRequest request,
 ExecutionAttributes executionAttributes)

Checks if trailing checksum is enabled and ChecksumMode is disabled for S3Client.getObject(GetObjectRequest) per request.

Parameters:

request - the request

executionAttributes - the executionAttributes

Returns:

true if trailing checksums is enabled and ChecksumMode is disabled, false otherwise

getObjectChecksumEnabledPerResponse

public static boolean getObjectChecksumEnabledPerResponse(SdkRequest request,
 SdkHttpHeaders responseHeaders)

Checks if trailing checksum is enabled for S3Client.getObject(GetObjectRequest) per response.

Parameters:

request - the request

responseHeaders - the response headers

Returns:

true if trailing checksums is enabled, false otherwise

shouldRecordChecksum

public static boolean shouldRecordChecksum(SdkRequest sdkRequest,
 ClientType expectedClientType,
 ExecutionAttributes executionAttributes,
 SdkHttpRequest httpRequest)

Validates that checksums should be enabled based on ClientType and the presence of S3 specific headers.

Parameters:

expectedClientType - - The expected client type for enabling checksums

executionAttributes - - ExecutionAttributes to determine the actual client type

Returns:

If trailing checksums should be enabled for this request.

responseChecksumIsValid

public static boolean responseChecksumIsValid(SdkHttpResponse httpResponse)

validatePutObjectChecksum

public static void validatePutObjectChecksum(PutObjectResponse response,
 ExecutionAttributes executionAttributes)

Client side validation for PutObjectRequest

Parameters:

response - the response

executionAttributes - the execution attributes
