`Static` assignDeepDefaultHandlers

assignDeepDefaultHandlers: AssignDeepHandler[] = ...

ObjectUtils.assignDeep 中默认转换结果的函数列表

Methods

`Static` assignDeep

assignDeep<T>(target: T, source: gPartial<T>, handlers?: AssignDeepHandler[], deep?: number): T
深度赋值从源数据取所有子代可枚举属性值赋值给目标对象
Type Parameters
- T
Parameters
- target: T
  
  被赋值对象
- source: gPartial<T>
  
  源数据
- handlers: AssignDeepHandler[] = []
  
  处理函数列表，先于 ObjectUtils.assignDeepDefaultHandlers 执行。函数返回值为true表示该属性赋值已完成跳过默认属性赋值操作，否则执行默认属性赋值操作。执行在 ObjectUtils.DefaultAssignDeepReplacers 前。
- deep: number = Number.MAX_SAFE_INTEGER
  
  赋值深度，deep<1时直接返回。
Returns T
- Defined in src/polyfill/ObjectUtils.ts:170

`Static` assignShallow

assignShallow<T>(target: T, source: Partial<T>): T
浅赋值从源数据取所有可枚举属性值赋值给目标对象
Type Parameters
- T
Parameters
- target: T
  
  目标对象
- source: Partial<T>
  
  源数据
Returns T
- Defined in src/polyfill/ObjectUtils.ts:149

`Static` equalDeep

equalDeep<T>(a: T, b: T): boolean
深度比较两个对象子代可枚举属性值
Type Parameters
- T
Parameters
- a: T
  
  第一个对象
- b: T
  
  第二个对象
Returns boolean
- Defined in src/polyfill/ObjectUtils.ts:199

`Static` getPropertyChains

getPropertyChains(object: any): string[]
获取对象上属性链列表

例如 object值为{ a: { b: { c: 1 }, d: 2 } }时则返回 ["a.b.c","a.d"]
Parameters
- object: any
  
  对象
Returns string[]
- Defined in src/polyfill/ObjectUtils.ts:94

`Static` getPropertyDescriptor

getPropertyDescriptor(object: any, property: string): PropertyDescriptor
从对象自身或者对象的原型中获取属性描述
Parameters
- object: any
  
  对象
- property: string
  
  属性名称
Returns PropertyDescriptor
- Defined in src/polyfill/ObjectUtils.ts:239

`Static` getPropertyValue

getPropertyValue(object: any, property: string | string[]): any
获取对象对应属性上的值
Parameters
- object: any
  
  对象
- property: string | string[]
  
  属性名称，可以是 "a" 或者 "a.b" 或者 ["a","b"]
Returns any
- Defined in src/polyfill/ObjectUtils.ts:73

`Static` isBaseType

isBaseType(object: any): boolean
判断是否为基础类型 undefined,null,boolean,string,number
Parameters
- object: any
Returns boolean
- Defined in src/polyfill/ObjectUtils.ts:25

`Static` isObject

isObject(object: any): boolean
判断是否为Object对象，构造函数是否为Object，检测 ObjectUtils.constructor === Object
Parameters
- object: any
  
  用于判断的对象
Returns boolean
- Defined in src/polyfill/ObjectUtils.ts:62

`Static` objectIsEmpty

objectIsEmpty(obj: any): boolean
判断对象是否为null或者undefine

Returns
Parameters
- obj: any
Returns boolean
- Defined in src/polyfill/ObjectUtils.ts:228

`Static` propertyIsWritable

propertyIsWritable(obj: any, property: string): boolean
属性是否可写
Parameters
- obj: any
  
  对象
- property: string
  
  属性名称
Returns boolean
- Defined in src/polyfill/ObjectUtils.ts:260

`Static` runFunc

runFunc<T>(obj: T, func: ((obj: T) => void)): T
执行方法

用例：
1. 给一个新建的对象进行初始化
startLifetime = ObjectUtils.runFunc(new MinMaxCurve(), (obj) => { obj.mode = MinMaxCurveMode.Constant; (<MinMaxCurveConstant>obj.minMaxCurve).value = 5; });
Type Parameters
- T
Parameters
- obj: T
  
  对象
- func: ((obj: T) => void)
  
  被执行的方法
  - - (obj: T): void
    - Parameters
      
      obj: T
      
      Returns void
Returns T
- Defined in src/polyfill/ObjectUtils.ts:50
