JMExecJNIMethodInContext

Executes a nonstatic Java method in a given AWT context thread using the Java Native Interface (JNI).

OSStatus JMExecJNIMethodInContext (
                     JMAWTContextRef context, 
                     JNIEnv* env, 
                     jobject objref, 
                     jmethodID methodID, 
                     UInt32 argCount, 
                     jvalue args[]);

context

The AWT context in whose thread you want the method to execute.

env

A pointer to the current JNIEnv data structure.

objref

A pointer to the Java object that contains the method you want to call.

methodID

The ID of the method.

argCount

The number of arguments in the method.

args[]

The argument list.

function result

A result code; see "JManager Result Codes".

DISCUSSION

Before calling this function, you must call the JMGetCurrentEnv function to get the JNIEnv pointer.

If you want to execute a static Java method (that is, one that is not local to an object) using the JNI, you must call the JMExecJNIStaticMethodInContext function instead.
