The java.lang.System class defines a number of well-known properties. For example, you can obtain the JVM's temporary directory by looking up the "java.io.tmpdir" property: ... = System.getProperty("java.io.tmpdir"); What I don't understand is why these properties aren't defined as constants (e.g. in the java.lang.System class). This...
Hello, Is there a method that returns all the keys for an object conforming to the NSKeyValueCoding protocol?

What are the benefits of only using public properties instead of using the public property to access a private variable? For example public int iMyInt { get; set; } instead of private int myint; public int iMyInt { get { return myint; } set { myint = value; } } Other than letting .NET manage the variable / memory underneath the ...

But the properties are only loaded when i specify a full abso...

Like I understand, @synthesize actually is generating the Getters and Setters. But what's @property then doing? Is it just setting up the parameters for that cool @synthesize magic function? ...
Hi, I have a Windows.Forms component which has a "mySize" property that returns a Size struct. My intention was to have this property calculate the returned mySize automatically based on the size of the component, unless mySize has been explicity set, in which case, return the set value of mySize. Unfortunately, now that I am embedding t...

I have an Obj-C 2.0 class that has an NSMutableArray property. If I use the following code, then the synthesised setter will give me an immutable copy, not a mutable one: @property (readwrite, copy) NSMutableArray *myArray; Is there any reason that Apple didn't implement the following syntax? @property (readwrite, mutablecopy) NSMuta...

I want to be able to set one of the properties on the child control from the XAML where I'm instantiating the main control. (Actually, I w...
