本文整理了Java中com.google.common.reflect.TypeToken.method()方法的一些代码示例，展示了TypeToken.method()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TypeToken.method()方法的具体详情如下：
包路径：com.google.common.reflect.TypeToken
类名称：TypeToken
方法名：method

TypeToken.method介绍

[英]Returns the Invokable for method, which must be a member of T.
[中]返回可调用的for方法，该方法必须是T的成员。

代码示例

@Override
 Object interfaceMethodCalled(Class<?> interfaceType, Method method) {
  return getDummyValue(TypeToken.of(interfaceType).method(method).getReturnType());
 }
};

代码示例来源：origin: google/guava

private static Invokable<?, ?> invokable(@Nullable Object instance, Method method) {
 if (instance == null) {
  return Invokable.from(method);
 } else {
  return TypeToken.of(instance.getClass()).method(method);
 }
}

代码示例来源：origin: google/guava

@Override
protected Object handleInvocation(Object proxy, Method method, Object[] args) {
 Invokable<?, ?> invokable = interfaceType.method(method);
 ImmutableList<Parameter> params = invokable.getParameters();
 for (int i = 0; i < args.length; i++) {
  Parameter param = params.get(i);
  if (!isNullable(param)) {
   checkNotNull(args[i]);
  }
 }
 return dummyReturnValue(interfaceType.resolveType(method.getGenericReturnType()));
}

代码示例来源：origin: google/guava

public void testMethod_notDeclaredByType() throws NoSuchMethodException {
 Method sizeMethod = Map.class.getMethod("size");
 try {
  TypeToken.of(List.class).method(sizeMethod);
  fail();
 } catch (IllegalArgumentException expected) {
 }
}

代码示例来源：origin: google/guava

@Override
 public Object handleInvocation(Object proxy, Method method, Object[] args) {
  // Crude, but acceptable until we can use Java 8.  Other
  // methods have default implementations, and it is hard to
  // distinguish.
  if (method.getName().equals(JUF_METHODS.get(typeName))) {
   return getDefaultValue(type.method(method).getReturnType());
  }
  throw new IllegalStateException("Unexpected " + method + " invoked on " + proxy);
 }
});

代码示例来源：origin: google/guava

List<Invokable<?, ? extends T>> factories = Lists.newArrayList();

 if (!invokable.isPrivate()
   && !invokable.isSynthetic()

代码示例来源：origin: google/guava

}

代码示例来源：origin: google/guava

   }

   Object[] args = new Object[parameters.size()];
   for (int i = 0; i < parameters.size(); i++) {
    args[i] = getDefaultValue(parameters.get(i).getType());
   }
   try {
    try {
     method.invoke(object, args);
    } catch (InvocationTargetException ex) {
     try {

      // this is a legit exception
     }
    }
   } catch (Throwable cause) {
    throw new InvocationTargetException(
      cause, method + " with args: " + Arrays.toString(args));
