      • sendMessage

        IJavaValue sendMessage​(String selector,
                               String signature,
                               IJavaValue[] args,
                               IJavaThread thread,
                               boolean superSend)
                        throws DebugException
        Returns the result of sending the specified message to this object with the given arguments in the specified thread. The given thread is resumed to perform the method invocation. The thread will suspend in its original location when the method invocation is complete. This method does not return until the method invocation is complete. Invoking a method in the target VM can result in breakpoints being hit, infinite loops, and deadlock.
        Parameters:
        selector - the selector of the method to be invoked
        signature - the JNI style signature of the method to be invoked
        args - the arguments of the method, which can be null or empty if there are none
        thread - the thread in which to invoke the method
        superSend - true if the method lookup should begin in this object's superclass
        Returns:
        the result of invoking the method
        Throws:
        DebugException - if this method fails. Reasons include:
        • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
        • This object does not implement the specified method
        • An exception occurs while invoking the specified method
        • The given thread is already performing a message send, (status code IJavaThread.ERR_NESTED_METHOD_INVOCATION)
        • The given thread is not currently suspended (status code IJavaThread.ERR_THREAD_NOT_SUSPENDED)
        • The given thread was explicitly suspended (status code IJavaThread.ERR_INCOMPATIBLE_THREAD_STATE)
      • sendMessage

                        throws DebugException
        Returns the result of sending the specified message on the specified declaring type to this object with the given arguments in the specified thread. The given thread is resumed to perform the method invocation. The thread will suspend in its original location when the method invocation is complete. This method does not return until the method invocation is complete. Invoking a method in the target VM can result in breakpoints being hit, infinite loops, and deadlock.
        Parameters:
        selector - the selector of the method to be invoked
        signature - the JNI style signature of the method to be invoked
        args - the arguments of the method, which can be null or empty if there are none
        thread - the thread in which to invoke the method
        typeSignature - the signature of the type in which the method is defined or null if the method should be invoked normally using polymorphism
        Returns:
        the result of invoking the method
        Throws:
        DebugException - if this method fails. Reasons include:
        • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
        • This object does not implement the specified method
        • An exception occurs while invoking the specified method
        • The given thread is already performing a message send, (status code IJavaThread.ERR_NESTED_METHOD_INVOCATION)
        • The given thread is not currently suspended (status code IJavaThread.ERR_THREAD_NOT_SUSPENDED)
        • The given thread was explicitly suspended (status code IJavaThread.ERR_INCOMPATIBLE_THREAD_STATE)
