由 谁都会走 提交于 2019-12-10 10:13:20
问题 I have data = { 'first': { 'number': 1, 'text': 'Ya.' }, 'second': { 'number': 10, 'text': 'Da.' } }; And I really want to access it like: number = data['first.number']; Actually in a more flexible way, like: numberOrText = data[memberName+'.'+propertyName]; Is there any lightweight library, or snippet you can suggest? This is - https://github.com/martinvl/KVCObject - so cool, but a bit overhead for this. 回答1: You can easily resolve keypath with reduce function , without using any library.

问题 I read a lot about JS accessors here and figure out this gonna be good for me: This is what I used for local fields: TYPE_DEFAULT_VALUE= { number: 0, string: "", array: [], object: {}, }; typeOf = function (object) { if (typeof object === "number" && isNaN(object)) return NaN; try { return Object.prototype.toString.call(object).slice(8, -1).toLowerCase(); } catch(ex) { return "N/A"; }; }; getAccessor = function(obj, key, type, defaultValue) { if (defaultValue === undefined) defaultValue =

问题 I don't understand accessor methods and I'm stuck with creating setAge, getAge and getName. This is the question: Add three accessor methods, setAge , getAge and getName . These methods should set and get the values of the corresponding instance variables. public class Player { protected int age; protected String name; public Player(String namArg) { namArg = name; age = 15; } } 回答1: An accessor method is used to return the value of a private or protected field. It follows a naming scheme

Accessor implementation of properties

问题 Is there some of documentation how the compiler auto-generates the accessors of properties? When writing custom accessors (overriding the synthesized ones), it would be nice to know the original implementation. Especially to see the differing implementations of accessors for properties with different (weak/strong/retain/copy etc..) attributes. 回答1: Is there some of documentation how the compiler auto-generates the accessors of properties? The compiler just adds a C function call. Peek at the

How do I change accessibility on an accessor using CodeDom?

由 ◇◆丶佛笑我妖孽 提交于 2019-12-06 11:00:35
问题 In C#, you can have more restrictive accessors on the accessors of a property like this: public List<String> Name { get; protected set; } How can I accomplish this when generating code using CodeDom? 回答1: CodeDom doesn't directly support this. CodeDom dates from an era when C# and Visual Basic didn't support different accessibility on the get and set method, and hasn't been updated to support the new functionality. You will probably need to use a CodeSnippetTypeMember (though with a bit of
