Here is the entire source code of the TraceKeyOuterClass.TraceKey:
https://gist.github.com/pdeva/26bd29fb5b9b842dd84d9d9d26018cc0
Its an autogenerated file by protoc. The hashCode actually is indeed
stable. Here is the hashCode() method of TraceKey (also in the gist above):
@java.lang.Override
public int hashCode() {
if (memoizedHashCode != 0) {
return memoizedHashCode;
}
int hash = 41;
hash = (19 * hash) + getDescriptor().hashCode();
hash = (37 * hash) + ACCOUNTID_FIELD_NUMBER;
hash = (53 * hash) + getAccountId().hashCode();
hash = (37 * hash) + TRACEID_FIELD_NUMBER;
hash = (53 * hash) + com.google.protobuf.Internal.hashLong(
getTraceID());
hash = (37 * hash) + ENV_FIELD_NUMBER;
hash = (53 * hash) + getEnv().hashCode();
hash = (29 * hash) + unknownFields.hashCode();
memoizedHashCode = hash;
return hash;
}
