方法详细信息

dataType

public String dataType() default ""

定义 Functions 运行时应如何处理参数值。 可能的值为：

<li>

  <p>"": get the value as a string, and try to deserialize to actual parameter type like POJO </p>

</li>

<li>

  <p>string: always get the value as a string </p>

</li>

<li>

  <p>binary: get the value as a binary data, and try to deserialize to actual parameter type byte[] </p>

</li>

Returns:

将由 Functions 运行时使用的 dataType。

name

public String name()

在函数代码中表示计时器对象的变量的名称。

Returns:

在函数代码中表示计时器对象的变量的名称。

schedule

public String schedule()
