WebAssembly.Module()
构造函数可以用来同步编译给定的 WebAssembly 二进制代码。不过,获取
Module
对象的主要方法是通过异步编译函数,如
WebAssembly.compile()
,或者是
通过 IndexedDB 读取 Module 对象.
构造函数语法
重要提示:由于大型模块的编译可能很消耗资源,开发人员只有在绝对需要同步编译时,才使用 Module()
构造函数;其他情况下,应该使用异步 WebAssembly.compile()
方法。
var myModule = new WebAssembly.Module(bufferSource);
参数
- bufferSource
- 一个 类型化数组 或 ArrayBuffer,包含要编译的 .wasm 模块的二进制代码。
Module
构造函数的方法属性
-
WebAssembly.Module.customSections()
-
给定
Module
对象和字符串,通过该字符串,返回 Module 对象中所有自定义部分的内容的副本。 -
WebAssembly.Module.exports()
-
给定
Module
对象,返回一个数组,内容是所有已声明的接口的描述。 -
WebAssembly.Module.imports()
-
给定
Module
对象,返回一个数组,内容是所有已声明的引用的描述。
Module
实例
所有 Module
实例继承自 Module()
构造函数的原型对象 —— 修改它会影响所有 Module
实例。
实例属性
-
Module.prototype.constructor
-
Returns the function that created this object's instance. By default this is the
WebAssembly.Module()
constructor. -
Module.prototype[@@toStringTag]
- The initial value of the @@toStringTag property is the String value "WebAssembly.Module".
实例方法
Module 实例没有自己的默认方法。
