Optional configuration for the observable, such as whether the value can be written by the client. 可观察对象的可选配置，例如该值是否可由客户端写入。

#Returns

ObservableBoolean

#Remarks

Creates a new ObservableBoolean with the provided initial boolean value. 使用提供的初始布尔值创建一个新的 ObservableBoolean。

#Methods

#getData()

getData(): boolean

World Mutation Early Execution Beta

#Returns

boolean

#Remarks

Returns the current boolean value held by this observable. 返回此可观察对象持有的当前布尔值。

#setData()

setData(data): void

World Mutation Early Execution Beta

#Parameters

#data

boolean

The new boolean value to set. 要设置的新布尔值。

#Returns

void

#Remarks

Updates the boolean value held by this observable. If the new value differs from the current value, all subscribed listeners are notified with the new value. 更新此可观察对象持有的布尔值。如果新值与当前值不同，则会使用新值通知所有已订阅的监听器。

#subscribe()

subscribe(callback): (arg0) => void

World Mutation Early Execution Beta

#Parameters

#callback

(arg0) => void

A function that receives the new boolean value each time the observable changes. 每次可观察对象发生变化时接收新布尔值的函数。

#Returns

(arg0) => void

#Remarks

Registers a callback to be invoked whenever the observable's value changes. Returns the callback, which can be passed to unsubscribe to remove the listener. 注册一个回调函数，当可观察对象的值发生变化时调用。返回该回调函数，可将其传递给 unsubscribe 以移除监听器。

#unsubscribe()

unsubscribe(callback): boolean

World Mutation Early Execution Beta

#Parameters

#callback

(arg0) => void

The callback handle previously returned by subscribe. 先前由 subscribe 返回的回调句柄。

#Returns

boolean

#Remarks

Removes a previously registered listener from this observable. Returns true if the listener was found and removed, false if it was not found. 从此可观察对象中移除先前注册的监听器。如果找到并移除了监听器，则返回 true；如果未找到，则返回 false。
