Unsolved QtAndroidExtras Source: Why some functions get QByteArray parameter?

[Ibrahim]

Hi; I saw some functions like this in qjni.cpp:

static jclass getCachedClass(const QByteArray &classBinEnc, bool *isCached = 0)
{
  ...
}

inline static jclass loadClass(const QByteArray &className, JNIEnv *env, bool binEncoded = false)
{
  ...
}

I don't know why this functions get QByteArray parameter for class name? Class name can be QString, std::string or const char*? Thanks.

maybe because of many diffrient languages (UTF, WIN-1250 ect.).

@Artmetic QString is 16bit Unicode, so it can handle different languages and encodings.
@Ibrahim I'm not JNI expert, but maybe the reason is that Qt needs to communicate with Java (JRE) and QByteArray is just an array of bytes - quite universal.
