    • invokeMethod

      @Nullable Object invokeMethod(@NonNull MethodId methodId, @Nullable Object @Nullable ... arguments) throws InvocationTargetException
      Invokes a method and gets the return value.

      The method must be taken from MethodMirror.TypeWalker.getViableMethods(), meaning it must be accessible and located in the type this TypeWalker is made for. This function is permitted to assume this precondition and may behave unexpectedly if it is not met.

      Parameters:
      methodId - the method to call
      arguments - method arguments. The array may be null for none, and the arguments may be boxed primitive objects to represent primitive values.
      Returns:
      the return value, boxing primitives if necessary
      Throws:
      InvocationTargetException - if the method threw a throwable, it is wrapped in this exception
