Method Detail

valueOf

public double valueOf()

Returns the primitive value of the Number object.

返回Number对象的原始值。

Returns:

the primitive value of the Number object. Number对象的原始值。

getNumberValue

public double getNumberValue()

Description copied from class: JSValue

Returns number value of the current JavaScript object if object represents a primitive number or Number object, otherwise throws IllegalStateException.

如果object表示原始数字或Number对象，则返回当前JavaScript对象的number值，否则抛出IllegalStateException。

Overrides:

getNumberValue in class JSValue

Returns:

number value of the current JavaScript object if object represents a primitive number or Number object. 当前JavaScript对象的number值（如果object表示原始数字或Number对象）。

isNumberObject

public boolean isNumberObject()

Description copied from class: JSValue

Indicates whether JavaScript value is a Number object. If this method returns true, then the value can be casted to JSNumberObject type. For example:

 if (value.isNumberObject()) {
     JSNumberObject numberObject = value.asNumberObject();
 }
 

指示JavaScript值是否为Number对象。如果此方法返回true，则可以将值强制转换为JSNumberObject类型。例如： 如果（value.isNumberObject（））{ JSNumberObject numberObject = value.asNumberObject（）; }

Overrides:

isNumberObject in class JSValue

Returns:

true when JavaScript value is a Number object. 当JavaScript值为Number对象时。

asNumberObject

public JSNumberObject asNumberObject()

Description copied from class: JSValue

Casts the current JavaScript object to JSNumberObject type. If the current object doesn't represent a Number object, the IllegalStateException error is thrown.

将当前的JavaScript对象转换为JSNumberObject类型。如果当前对象不代表Number对象，则抛出IllegalStateException错误。

Overrides:

asNumberObject in class JSValue

toString

public java.lang.String toString()

Overrides:

toString in class JSObject
