I would like to understand how the built-in function property works. What confuses me is that property can also be used as a decorator, but it only takes arguments when used as a built-in function ...
A property can have a 'get' accessor only, which is done in order to make that property read-only When implementing a get/set pattern, an intermediate variable is used as a container into which a value can be placed and a value extracted.
In my situation I had my property auto initialize a command in a ViewModel for a View. I changed the property to use expression bodied initializer and the command CanExecute stopped working. Here's what it looked like and here's what was happening.
Descriptors like property need to be in the type's dictionary to work their magic. So those in a class definition primarily affect the behaviour of instances of the class, with minimal effect on the behaviour of the class itself (since the class is the type of the instances).
Despite having a correct connection string in my appsettings.json, I am encountering an InvalidOperationException stating that the ConnectionString property has not been initialized.
187 We may get the message Property has no initializer and is not definitely assigned in the constructor when adding some configuration in the tsconfig.json file so as to have an Angular project compiled in strict mode:
45 Following is an ES6 example of how you can access the property of an object using a property name that has been dynamically generated by concatenating two strings.
6 Yes, for the original example posted, the property will work exactly the same as simply having an instance variable 'x'. This is the best thing about python properties. From the outside, they work exactly like instance variables! Which allows you to use instance variables from outside the class.
