oop - Are abstract members possible in PHP? -

i'd develop abstract class extended fit custom requirements. of methods implemented in base class. however, rely heavily on values set in members, child class should define. reason i'm saying "abstract" class want force extenders of class define values members. possible? i know can define methods abstract , force extenders implement those. i'm not sure members. furthermore, design practice? example: abstract class foo_bar { // want child class define these private $member1 = 0; private $member2 = 0; private $member3 = 0; // child class , instances can access public function foo() { return 'foo'; } // child class must implement abstract function bar(); } in short: no. there's no such thing abstract properties in php. you may declare properties protected in abstract class child inherits them. if you'd declare them abstract , there's no guarantee child implements them with us...

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...

c# - Can LINQ be used to pull keywords out of a string? -

if have long-ish string of text , wanted pull out words greater 4 characters in length , found more 4 times in string, can linq that? you may able tighten up, believe effect of var results = inputstring.split() .where(word => word.length > 4) .groupby(word => word) .where(grp => grp.count() > 4) .select(grp => grp.key); you will, of course, need decide how wish deal punctuation might present. so given input var inputstring = @"the quick brown fox jumped on lazy dog quick brown fox jumped on lazy dog quick fox jumped on lazy dog quick fox jumped on lazy dog quick brown fox jumped on lazy dog"; the results contain "quick" , "jumped" because other word greater 4 characters ("brown") appeared 3 times.

Default value of $#ArrayName when there is no element (Perl) -

Differences between Image and BitmapImage with Flex? -

in image 's asdoc, can see : flex includes bitmapimage class. class used embedding images skins , fxg components but can use image in skins , use @embed image ... therefore, , when should use image or bitmapimage please ? image skinnable class wraps bitmapimage . such bitmapimage more lightweight, image has more features. question when use boils down this: if features of bitmapimage suffice, use that; otherwise use image. in mobile environments try favor use of bitmapimage. now features image add exactly? image extends skinnablecomponent: means can assign images skin border or dropshadow or whatever consistently throughout application. it provides progress indicator can displayed while image loading. one more feature possibility queue loading of multiple images .

data structures - Java : Datastructure to stock lots of words -

i have stock lots of word (+200k) in java program , want access them fast. need know if given word belongs "dictionary". don't need pair <word, smthg> . if possible i'm searching solution in standard library. ps : maybe using data structure not better way ? reading each time file containing words more efficient ? edit : it's small project. have deal effectiveness , memory last edit : choose hashset. use java sets because sets linear sorted data structure treeset. searching, techniques binary search can implemented , fast no repetition. this structure of java sets. also not going allow duplication hence reducing redundancy , save memory. if want know various searching algorithms complexities refer link. here is http://bigocheatsheet.com/

sonarqube - SONAR undocumented public API skewed by unit tests -

the sonar metrics include section evaluating documentation quality, having item public undocumented api . high in our project because reports each , every unit test. however, unit test methods have public junit. is there easy way remove unit test methods undocumented api metric ? i'm aware of these alternatives: we add javadoc comments each test method. not useful, pollutes code. the tests in eclipse test fragment projects. exclude test classes sonar analysis. however, want have same rules applied test code , production code (e.g. when checking violations). i have not found section in sonar configuration matching metric, may have missed it. this metric not fed unit test classes, must have missed in configuration. as example, check out sonar analysed sonar (on nemo) : you'll see no test class reported "public_undocumented_api".

On what basis ruby and ruby on rails versions are named -

i curious on basis ruby , ror versions named. example, after ruby 1.9.3, version 2.0 instead of 1.10 or 1.9.4, , in rails. there must convention or rule. ruby , rails, many other projects follow semantic versioning . they don't follow letter, though. example, ruby 1.9 backwards-incompatible ruby 1.8, whereas ruby 2.0 compatible ruby 1.9, ruby 1.9 should have been ruby 2.0 , ruby 2.0 should have been ruby 2.1. in particular case, there historic "marketing" reasons that: term "ruby 2.0" has been used in ruby community on 10 years mark specific "mythical" version specific, talked-about features scoped monkey patching , traits. releasing version without features still calling "2.0" have been more confusing breaking rules of semantic versioning. (actually, ruby 2.0 was released without traits , it has led confusion !) otoh, impossible call "1.10", because ruby_version constant returns version string , , lot of too...
