In the SPEED and CODE_SIZE runtimes, -// strings are not stored as java.lang.String in the Message because of two -// issues: -// -// 1. It wouldn't roundtrip byte arrays that were not vaid UTF-8 encoded -// strings, but rather fields that were raw bytes incorrectly marked -// as strings in the proto file. This is common because in the proto1 -// syntax, string was the way to indicate bytes and C++ engineers can -// easily make this mistake without affecting the C++ API. By converting to -// strings immediately, some java code might corrupt these byte arrays as -// it passes through a java server even if the field was never accessed by -// application code. -// -// 2. There's a performance hit to converting between bytes and strings and -// it many cases, the field is never even read by the application code. This -// avoids unnecessary conversions in the common use cases. -// -// In the LITE_RUNTIME, we store strings as java.lang.String because we assume -// that the users of this runtime are not subject to proto1 constraints and are -// running code on devices that are user facing. That is, the developers are -// properly incentivized to only fetch the data they need to read and wish to -// reduce the number of allocations incurred when running on a user's device. - -// TODO(dweis): Consider dropping all of the *Bytes() methods.
