CallObjectMethod(IntPtr, IntPtr)
Calls a Java instance method that returns an object reference.
public static IntPtr CallObjectMethod(IntPtr jobject, IntPtr jmethod);static member CallObjectMethod : nativeint * nativeint -> nativeintParameters
- jobject
-
IntPtr
nativeint
A live JNI object reference from the current VM, usable on the calling thread until the call returns or throws.
- jmethod
-
IntPtr
nativeint
A live instance method ID applicable to jobject. Its JNI signature must take no arguments and return an object reference. Keep its declaring class live.
Returns
nativeint
A local JNI reference to the returned object, or Zero if the method returns null. A nonzero local reference is valid only on its creating thread and may be released with DeleteLocalRef(IntPtr).
