Method Detail

getJMethodID

JNI.JMethodID getJMethodID()

Returns a method JNI JNI.JMethodID.

getDisplayName

String getDisplayName()

Returns a method display name used for logging.

findMethod

static HotSpotCalls.JNIMethod findMethod(JNI.JNIEnv env,
                                         JNI.JClass clazz,
                                         boolean staticMethod,
                                         String methodName,
                                         String methodSignature)

Finds a HotSpotCalls.JNIMethod in the given clazz with the given name and signature. If such a method does not exist throws JNIExceptionWrapper wrapping a NoSuchMethodError.

findMethod

static HotSpotCalls.JNIMethod findMethod(JNI.JNIEnv env,
                                         JNI.JClass clazz,
                                         boolean staticMethod,
                                         boolean required,
                                         String methodName,
                                         String methodSignature)

Finds a HotSpotCalls.JNIMethod in given clazz with given name and signature. If such a method does not exist and required is true, it throws JNIExceptionWrapper wrapping a NoSuchMethodError. If required is false it clears the pending JNI exception and returns a C NULL pointer.
