API Host ScriptProxy
将读取、写入、删除行为委托给脚本闭包处理器的运行时代理对象。
Runtime proxy object that delegates get/set/delete behavior to script closure handlers.
命名空间:AuroraScript.Runtime.Types。类型:class。
Namespace:
AuroraScript.Runtime.Types. Kind: class.
ScriptProxy 是公开宿主类型。通过下方签名选择调用方式;对运行时对象、生命周期和异常,应由宿主在边界处明确处理。
Runtime proxy object that delegates get/set/delete behavior to script closure handlers.
注意
选项对象需要名为 get、set 或 unset 的脚本闭包。
The options object expects script closures named get, set, or unset.
下面是 ScriptProxy 的最小使用方式。
A minimal use of
ScriptProxy.
// ScriptProxy 依赖脚本闭包处理器,通常直接在脚本中创建。
@module(MAIN);
export func run() {
var target = { value: 42 };
return new Proxy(target, {
get: (obj, key) => obj[key]
});
}创建 ScriptProxy 实例。
Use the member according to its public signature.
Parameters:
-
target
操作的目标对象。Target object for the operation.
-
options
控制此操作的配置。Configuration controlling this operation.
Returns
新建的 ScriptProxy 实例。
A new
ScriptProxyinstance.
调用示意
以下示例展示调用形状;将占位实例和参数替换为宿主中的实际值。
The example shows the call shape; replace placeholder instances and arguments with actual host values.
var value = new ScriptProxy(/* 参数 */);签名
void Define(string key, ScriptObject value, bool writeable = true, bool enumerable = true)void Define(string key, ScriptDatum value, bool writeable = true, bool enumerable = true)
调用 Define 完成其公开操作。
Use the member according to its public signature.
Parameters:
-
key
要查找或保存的键。Key to look up or store.
-
value
要处理、保存或转换的值。Value to process, store, or convert.
-
writeable
按签名提供的bool参数。The
boolparameter required by the signature. -
enumerable
成员是否参与枚举。Whether the member participates in enumeration.
Returns
无。
None.
