Function objects to names in the example , but that is not strictly necessary . we could instead simply nest the definitions . for readability we do it this way ; but also because 我們定義的每一個閉包函數(shù)都攜帶了函數(shù)范圍內(nèi)定義的任何值,然后將這些值綁定到函數(shù)對象的全局范圍。
But just as we can use the number 23 without binding it to any name in other words , as a function argument , we can use the function object we created with 閉包就象是fp的jekyll對于oop的hyde (角色或者也可能對調(diào)) 。閉包類似對象示例,是一種將一大批數(shù)據(jù)和功能封裝在一起的一種方式。
From multimethods import dispatch " multimethods " is generally a synonym for multiple dispatch ; but the name multimethod suggests the concrete function object handling the more abstract concept multiple dispatch . an instance of “多元法( multimethods ) ”通常是多分派的同義詞;但是多元法這個名稱暗示著處理較抽象的概念時應(yīng)采用具體的函數(shù)對象。
If the name denotes a valid class attribute that is a function object , a method object is created by packing ( pointers to ) the instance object and the function object just found together in an abstract object : this is the method object 如果這個命名確認為一個有效的函數(shù)對象類屬性,就會將實例對象和函數(shù)對象封裝進一個抽象對象:這就是方法對象。
When the method object is called with an argument list , it is unpacked again , a new argument list is constructed from the instance object and the original argument list , and the function object is called with this new argument list 以一個參數(shù)列表調(diào)用方法對象時,它被重新拆封,用實例對象和原始的參數(shù)列表構(gòu)造一個新的參數(shù)列表,然后函數(shù)對象調(diào)用這個新的參數(shù)列表。
For instance , while a function object has parameters associated with it in all the visual studio languages , in visual c the function can have additional properties unique to the c language , such as being virtual , a constant , or part of an idl file 例如,某個函數(shù)對象在所有visual studio語言中均具有與其相關(guān)聯(lián)的參數(shù)時,而在visual c + +中,此函數(shù)可以包含c + +語言中特有的附加屬性,如虛擬性、常數(shù)或idl文件的一部分。
Also in this paper , we modify the control function object function and the separation condition of system , and point out more precise and more correct conditions . in the view of material mechanics and structural mechanics , we analyze the results we get and make them more persuaded 另外,本文還對前人工作中的目標函數(shù)、控制函數(shù)及系統(tǒng)解體條件進行了研究和改進,提出了更加準確、更加科學(xué)的目標函數(shù)、控制函數(shù)和系統(tǒng)解體條件,并且我們還對所得到的結(jié)果從材料力學(xué)和結(jié)構(gòu)力學(xué)上進行了分析,使得所得結(jié)果更具有依據(jù)和說服力。
