C++ const in getter [duplicate]

There is a huge difference between the two ways. const bool isReady() The code above will return a const bool, but it does not guarantee that the object will not change its logic state. bool isReady() const This will return a bool, and it guarantees that the logic state of your object will not change. … Read more

How to exclude getter only properties from type in typescript

While readonly does not directly affect whether types are assignable, it does affect whether they are identical. To test whether two types are identical, we can abuse either (1) the assignability rule for conditional types, which requires that the types after extends be identical, or (2) the inference process for intersection types, which throws out … Read more

Please explain Getter and Setters in Objective C [duplicate]

Getter is a method which gets called every time you access (read value from) a property (declared with @property). Whatever that method returns is considered that property’s value: @property int someNumber; … – (int)someNumber { return 42; } … NSLog(“value = %d”, anObject.someNumber); // prints “value = 42” Setter is a method which gets called … Read more

MVVM: Should a VM object expose an M object directly, or only through getters delegating to M’s getters?

There is not a general agreement about that question. For example it was one of the open questions about MVVM formulated by Ward Bell here: Is the VM allowed to offer the V an unwrapped M-object (e.g., the raw Employee) ? Or must the M-object’s properties (if it is even permitted to have properties!) be … Read more

Lambda expression for setter

I’m not sure what you mean by creating a lambda expression for the setter. What it looks like you are trying to do is to assign the method reference to a suitable Functional Interface. In that case, the best match is to a BiConsumer: BiConsumer<Student, String> studentNameSetter = Student::setName;

Passing Argument to JavaScript Object Getter

Getters do not require explicit invocation with parentheses and cannot therefore accept arguments. Their invocation is implicit via standard property access syntax, e.g. URIController.href. From getter documentation on MDN: The get syntax binds an object property to a function… It must have exactly zero parameters ______ If you need to accept arguments, use a function … Read more

Python overriding getter without setter

Use just the .getter decorator of the original property: class superhuman(human): @human.name.getter def name(self): return ‘super ‘ + self._name Note that you have to use the full name to reach the original property descriptor on the parent class. Demonstration: >>> class superhuman(human): … @human.name.getter … def name(self): … return ‘super ‘ + self._name … >>> … Read more

Jackson Not Overriding Getter with @JsonProperty

The problem was that I was using both the old and new jackson libraries i.e. before I had import org.codehaus.jackson.annotate.JsonProperty; Which I had to change to below, to be consistent with the library I was using. Since I was using maven that also meant updating my maven dependencies. import com.fasterxml.jackson.annotation.JsonProperty; For it to work, I … Read more
