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

Finds a JNICalls.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 JNICalls.JNIMethod findMethod(JNI.JNIEnv env,
                                     JNI.JClass clazz,
                                     boolean staticMethod,
                                     boolean required,
                                     String methodName,
                                     String methodSignature)

Finds a JNICalls.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.
