getter

I would like to know a good syntax for C++ getters and setters. private: YourClass *pMember; the setter is easy I guess: void Member(YourClass *value){ this->pMember = value; // forget about deleting etc } and the getter? should I use references or const pointers? example: YourClass &Member(){ return *this->pMember; } or YourClass *Member() const{ return this->member; } whats the difference between them? Thanks, Joe EDIT: sorry, I will edit my question... I know about references and pointers, I was asking about references and const pointers, as getters, what would be the difference between

I do sometimes see abbreviations in properties for the getter. E.g. those two types: public int Number { get; } = 0 public int Number => 0; Can someone please tell me if there are any differences between those two. How do they behave? Are both of them read-only? Yes, both of them are read-only, but there is a difference. In the first one, there's a backing field which is initialized to 0 before the constructor is executed. You can change the value only in the constructor , just like a regular read-only field. The getter itself just returns the value of the field. In the second one, the getter

What convention do you use to comment getters and setters? This is something I've wondered for quite some time, for instance: /** * (1a) what do you put here? * @param salary (1b) what do you put here? */ public void setSalary(float salary); /* * (2a) what do you put here? * @return (2b) */ public float getSalary(); I always find I'm pretty much writing the exact same thing for 1a/b and 2a/b, something like 1a) Sets the salary of the employee, 1b) the salary of the employee. It just seems so redundant. Now I could see for something more complex you might write more in the (a) parts, to give

I need to get the value of a field with a specific annotation, So with reflection I am able to get this Field Object. The problem is that this field will be always private though I know in advance it will always have a getter method. I know that I can use setAccesible(true) and get its value (when there is no PermissionManager), though I prefer to invoke its getter method. I know that I could look for the method by looking for "get+fieldName" (though I know for example for boolean fields are sometimes named as "is+fieldName"). I wonder if there is a better way to invoke this getter (many

I am familiar with Java, but just starting to learn JavaFX, and specifically learn about JavaFX properties. I understand the basic design pattern as shown in the following example from Oracle: package propertydemo; import javafx.beans.property.DoubleProperty; import javafx.beans.property.SimpleDoubleProperty; class Bill { // Define a variable to store the property private DoubleProperty amountDue = new SimpleDoubleProperty(); // Define a getter for the property's value public final double getAmountDue(){return amountDue.get();} // Define a setter for the property's value public final void

For whatever reason, Javascript getters/setters for custom objects seem to work with any browser but IE. Does IE have any other non-standard mechanism for this? (As with many other features) If not, are there any workarounds to achieve the same functionality? Nosredna IE8 has it through defineProperty , but only for DOM objects. But supposedly, it'll eventually come for JavaScript objects as well. linusthe3rd Resig's post references his env.js implementation being the first time he uses the getters and setters methodology you are looking for. The reason this style of works fine for him is

If I get a NullPointerException in a call like this: someObject.getSomething().getSomethingElse(). getAnotherThing().getYetAnotherObject().getValue(); I get a rather useless exception text like: Exception in thread "main" java.lang.NullPointerException at package.SomeClass.someMethod(SomeClass.java:12) I find it rather hard to find out wich call actually returend null, often finding myself refactoring the code to something like this: Foo ret1 = someObject.getSomething(); Bar ret2 = ret1.getSomethingElse(); Baz ret3 = ret2.getAnotherThing(); Bam ret4 = ret3.getYetAnotherOject(); int ret5 = ret4
