Get a list of all Java reserved Keywords

安稳与你 提交于 2020-01-13 09:45:10
问题 I'm looking for a way to retrieve all the saved keywords in Java into some kind of data structure. For example: "for, while, if, else, int, double, etc." I need to do a name validation on a string, to be specific, I need to make sure it does not equal to any java keywords. Is there a specific way of retrieving all the keywords into one data structure? or do I need to just build a regex string with all these keywords in it : "for|while|if|..." and try and match my string against it? Thanks 回答1

How to turn keyword on a site into links with jQuery

南楼画角 提交于 2020-01-11 11:48:12
问题 I'm trying to turn a set of keywords into links on my site. I am currently using this code which will turn one keyword into a link. However, now I want to expand it to have several words. The link will always be the same, however, the keyword changes, so the link text must also reflect that. Here is the code I am currently using: <script type="text/javascript"> (function($) { var thePage = $("body"); thePage.html(thePage.html().replace(/Wedding Stationery/ig, '<a class="discrete" href="http:/

Use the keyword class as a variable name in C++

浪子不回头ぞ 提交于 2020-01-11 01:00:30
问题 I am having trouble writing C++ code that uses a header file designed for a C file. In particular, the header file used a variable name called class: int BPY_class_validate(const char *class_type, PyObject *class, PyObject *base_class, BPY_class_attr_check* class_attrs, PyObject **py_class_attrs); This works in C as class isn't taken as a keyword, but in C++, class is. So is there anyway I can #include this header file into a c++ file, or am I out of luck? Thank you. 回答1: try something like

Why does the 'sealed' keyword exist in .Net?

荒凉一梦 提交于 2020-01-09 10:38:06
问题 A large number of classes in the .Net framework are marked as 'sealed', preventing you from inheriting those classes with your own. Surely this goes against the nature of object orientation, where you can extend and redefine the behaviour of existing objects. Is there a good reason for the existence of the 'sealed' keyword? As an example, NotifyCollectionChangedEventArgs in Silverlight is sealed. I wanted to create my own version of ObservableCollection that supported AddRange and RemoveRange

C# - Event keyword advantages?

陌路散爱 提交于 2020-01-09 06:24:05
问题 I've come to recently understand that a C# 'event' really is. It isn't really anything, honestly. To sum up my findings: The event keyword is simply a modifier that only applies to delegates. So, all the 'magic' of an event are the operations of a delegate. That's it. I've read through a lot of the Microsoft documentation, but there no sentence that summarizes in that manner so succinctly. To continue with my findings, delegate, class, and struct are all on the same 'level'. They are ways to

Why were True and False changed to keywords in Python 3

梦想与她 提交于 2020-01-09 03:24:29
问题 In Python 2, we could reassign True and False (but not None ), but all three ( True , False , and None ) were considered builtin variables. However, in Py3k all three were changed into keywords as per the docs. From my own speculation, I could only guess that it was to prevent shenanigans like this which derive from the old True, False = False, True prank. However, in Python 2.7.5, and perhaps before, statements such as None = 3 which reassigned None raised SyntaxError: cannot assign to None

searching a keyword in DAX

问题 I am trying to create a column in power BI that searches for a keyword in a column of a table and returns a category. For example: in table 1 there is a column with feedback and if it contains any keyword in the keyword column of table 2 ( which is updated regularly) a TRUE value is returned. The following code works great if the keyword is the only word in the sentence like "product broke after using it once" returns FALSE if looking for the keyword "broke" and the word "broke" used as the
