Class PrecomputedSha256Checksummer

java.lang.Object

com.ibm.cos.v2.http.auth.aws.internal.signer.PrecomputedSha256Checksummer

All Implemented Interfaces:

Checksummer

public final class PrecomputedSha256Checksummer
extends Object
implements Checksummer

An implementation of a checksummer that simply passes along a computed value as a checksum. Specifically, this is used in the cases where the checksum is a pre-defined value that dictates specific behavior by the signer, and flexible checksums is not enabled for the request (such as aws-chunked payload signing without trailers, unsigned streaming without trailers, etc.).
