let's have class a has inner class a::impl . class allowedtoaccess should able a::impl& class a , no other class should able or know class a::impl exists. class a_1 { public: class impl; impl& impl(); const impl& impl() const; private: std::unique_ptr<impl> m_impl; }; class a_2 { private: friend class allowedtoaccess; class impl; std::unique_ptr<impl> m_impl; }; class a_3 { private: friend class allowedtoaccess; class impl; class implcontainer { friend class a_3; std::unique_ptr<impl> impl; } m_implcontainer; impl& impl(); // return *m_implcontainer.impl; const impl& impl() const; // return *m_implcontainer.impl; }; here code illustrate ideas. a_1 pros: m_impl secured. cons: classes not supposed know a::impl know (although don't know a::impl about). a_2 pros: classes not supposed know a::impl not know it. cons: m_impl not secured ( a...

this general question, i'm sure has been asked before, resources i'm finding suffer typical coder problem of assuming know things don't know. i'm trying use openshift deploy spring mvc project github repo. don't know github link supposed contain. i assumed github repo should contain code of project, i'm linking of development code to. however, when applying result 404 page no additional information. does github repo require war? need set in specific way? i've been able deploy project war server, know code working properly, can't seem find documentation on expectations project design openshift has github repo. am doing right? problem github contents, or elsewhere? you should try creating default project whichever java server cartridge using, , @ structure. it's standard maven project, there difference in pom.xml knows how deploy war file compiles.

okay, bear me on this, know it's going horribly convoluted, please me understand what's happening. from functools import partial class cage(object): def __init__(self, animal): self.animal = animal def gotimes(do_the_petting): do_the_petting() def get_petters(): animal in ['cow', 'dog', 'cat']: cage = cage(animal) def pet_function(): print "mary pets " + cage.animal + "." yield (animal, partial(gotimes, pet_function)) funs = list(get_petters()) name, f in funs: print name + ":", f() gives: cow: mary pets cat. dog: mary pets cat. cat: mary pets cat. so basically, why not getting 3 different animals? isn't cage 'packaged' local scope of nested function? if not, how call nested function local variables? i know running these kind of problems means 1 'doing wrong', i'd understand happens. the nested function loo...

in java program want kill process named "dummybroker"(which java program). kill using taskkill needs pid of process. how can fetch pid specific java process , kill it? you should take @ link : killing process using java and use : runtime.getruntime().exec("taskkill /f /im <processname>.<extension>") otherwise can maybe use combinaison of tasklist and split find containing line , find pid .

if managing project , have 2 developers working me , starting track project today. project located publicly on www.somedomain.com . then create centralized repository would: //ssh + cd directory want track, git init --bare myrootdirectory.git then developers working on project clone repository onto local machine , use wish, making changes , developing projects on local machine. bit confused. how developers commit code onto central repository, if used --bare , wouldn't prevent them doing that? what happens after project component has been tested developer , track on centralized repository used --bare on? also, changes developers make on local machine commit, available on local machine, or on centralized repository well? read there link between centralized repository , local 1 on developers machine, why asking. i appreciate clarification, in advance! the answer 2 git repositories, (one bare, , 1 not), linked hooks. can read more in this article , i'll ...
