By missing methods I mean comparasion operators.
Some JNI functions, for example GetObjectClass don't handle NULLs.
Should we pass NULLs to such functions and crash or check for NULLs and throw an exception (and don't call functions)?
While java::Object has methods like Wait and Notify, there is no monitor lock class to emulate Java's 'synchronized' construct.
Create java::Synchronizer class that would perform JNIEnv::MonitorEnter/MonitorExit.
Currently bad_cast is thrown without any message.
It should be thrown with a message like ("Can't cast %s to %s.",object->GetClass(),Type::JClass()).
Implement parser for field & method declarations, so one can write
Field(Tag,"private static int m_data")
Method(Tag,"public java.lang.Object doStuff()")
instead of
Field(Tag,"m_data","I")
Method(Tag,"doStuff","()Ljava/lang/Object;")
java::Array<java::ObjectPointer<X>> will work, but with unpleasant effects.
Either disallow such constructs, or detect, infer and use type X.
Add _RethrowException() before return.
Currently each call to GetLength() results in a call to GetStringLength(). We should cache length and use it in other functions.
Sometimes overhead of declaring JNIpp class (via JB_ macros) is just too much.
There should some 'quick' way of doing calling methods or manipulating variables.
Something like this:
java::PString var = java::CallMethod("System","String getenv(String)", java::PString::New("MY_VAR");
int ival = java::GetField("MyClass", "int mVar", myObject);
Note that functions return generic object that has different conversion operators. However, only proper conversion will succeed, all others will throw. E.g. the following will compile but will throw:
java::PObject obj = java::GetField("MyClass", "int mVar", myObject);
It's a shame that library doesn't support them!
