keyword

This is a silly question, but you can use this code to check if something is a particular type... if (child is IContainer) { //.... Is there a more elegant way to check for the "NOT" instance? if (!(child is IContainer)) { //A little ugly... silly, yes I know... //these don't work :) if (child !is IContainer) { if (child isnt IContainer) { if (child aint IContainer) { if (child isnotafreaking IContainer) { Yes, yes... silly question.... Because there is some question on what the code looks like, it's just a simple return at the start of a method. public void Update(DocumentPart part) { part

I found a strange keyword in NSObject.h - (oneway void)release; I searched the web, and learned it relates to asynchronous message passing, which looks similar with Erlang's message passing. It seems this can make many interesting things. What are some good use-cases of this keyword? ughoavgfhw oneway is used with the distributed objects API, which allows use of objective-c objects between different threads or applications. It tells the system that it should not block the calling thread until the method returns. Without it, the caller will block, even though the method's return type is void.

In C and many other languages, there is a continue keyword that, when used inside of a loop, jumps to the next iteration of the loop. Is there any equivalent of this continue keyword in Ruby? Ian Purton Yes, it's called next . for i in 0..5 if i < 2 next end puts "Value of local variable is #{i}" end This outputs the following: Value of local variable is 2 Value of local variable is 3 Value of local variable is 4 Value of local variable is 5 => 0..5 next also, look at redo which redoes the current iteration. sberkley Writing Ian Purton's answer in a slightly more idiomatic way: (1..5).each do

So an optional parameter expected in the web POST request of an API I'm using is actually a reserved word in python too. So how do I name the param in my method call: example.webrequest(x=1,y=1,z=1,from=1) this fails with a syntax error due to 'from' being a keyword. How can I pass this in in such a way that no syntax error is encountered? Pass it as a dict. func(**{'as': 'foo', 'from': 'bar'}) args = {'x':1, 'y':1, 'z':1, 'from':1} example.webrequest(**args) // dont use that library 来源： https://stackoverflow.com/questions/4179175/python-named-argument-is-keyword

It is frequent in my practice that a variable/argument is to store a type of something (as an enumeration value usually). And it usually makes no sense to specify an entity class in the name (like userType when a function is onlu intended to handle users). Is there a way I can use the "type" word for my needs instead of using scaffolds like "tipe", "kind", "somethingType" instead of it? The actual Scala type keyword is of such a rare use - it would be nice If I could undefine it (as a keyword) in the most of my code files. You can escape with backticks: val `type` = 5 来源： https://stackoverflow

With the JSON defined as it is, in order to deserialize it as an object, I'd need to create a property on my class called "event", which is a C# keyword. Is there another way to tell it what the field names will be? Here's an example of the JSON: { event: 123 data: {"data":"0D0401","ttl":"60","published_at":"2014-04-16T18:04:42.446Z","id":"48ff6f065067555031192387"} } Here are my classes that won't compile because of the keyword: public class Event { public int event { get; set; } public EventDetail data { get; set; } } public class EventDetail { public string data { get; set; } public string
