How can I explain the A a = new B ();? - Software Engineering Stack . . . The way I prefer to think of inheritance hierarchies including interfaces is by understanding that "subclass" and "subtype" are different qualities B is a subclass of A, but a subtype of A and IA Subtyping relationships are important for defining what variable type you can assign some entity to, and subclass relationships are important for defining what behaviour some entity has
Class A, B, C, D Real Estate: A Guide to Property Class Types New real estate investors may wonder what the terms Class A, B, C, and D property mean Classifying property is in part about age but should also consider things like affordability, amenities, and livability This is important, as identifying a property's class can predict how the asset might perform Learn more here
If class B extends A, can we say that B depends on A? When B extends A, then B is an A (inheritance) B has access to the protected members of A and is a deeper form of coupling When B holds a reference to A, then B uses an A Now A is a dependency of B (and therefore B depends on A) B only requires the public members of A and is a looser form of coupling than inheritance
Adding new service into existing micro-service system Existing services knowing about what events commands that new service supports Existing thought is if you already have two services (A and B) before introducing C, and A needs to do things when events from C happen, you end up creating a new version of A along with adding C to the mix
How to Calculate Cap Rate ( Where Many People Get It Wrong) The easiest way to define cap rate is the expected return (as a percent) an investment will generate based on the net operating income On its face, the calculation is simple Yet many in the real estate industry still get it wrong, failing to factor in all expenses or dig deep enough to uncover the true value
git - Working on a branch with a dependence on another branch that is . . . As result of running git checkout feature_b; git rebase feature_a you may get conflicts or some funny commits containing commits reverting new changes of feature_a This is usually solvable by using --interactive and skipping commits taken from the old version of the other branch (I had to do this several times recently)
Repository Pattern and Joined Queries - Software Engineering Stack Exchange How do you handle needing both entity-specific operations (e g an MVC backend that allows CRUD on tables, one entity at a time, which would require entity-specific repositories) and the abstracted operations (which operate on more than one entity type, thus using your absracted repository suggestions)? Create both types of repositories? How do you then avoid WET when Foo has a certain IsBar
