java - Are multiple 'if' statements and 'if-else-if' statements the same for mutually exclusive conditions? -

is there difference between writing multiple if statements , if-else-if statements ? when tried write program multiple if statements, did not give expected results, worked if-else-if . the conditions mutually exclusive. when write multiple if statements, it's possible more 1 of them evaluated true, since statements independent of each other. when write single if else-if else-if ... else statement, 1 condition can evaluated true (once first condition evaluates true found, next else-if conditions skipped). you can make multiple if statements behave single if else-if .. else statement if each of condition blocks breaks out of block contains if statements (for example, returning method or breaking loop). for example : public void foo (int x) { if (x>5) { ... return; } if (x>7) { ... return; } } will have same behavior : public void foo (int x) { if (x>5) { ... } else if (x>7)

openid - Skip IdentityServer3 login screen -

Image
we have configured client app use identityserver3 authentication via openid connect protocol (it's asp.net mvc app uses owin middleware support oidc). the identityserver3 configured use both local login , external login (azure ad, instance). in regular flow once app need authenticate user redirects him identityserver3 login screen - it's fine. in cases, on per-request basis, want bypass login screen somehow letting identityserver3 know user want login specific external identity provider right away. is possible do? just found solution in identityserver3's authorization/authentication endpoint documentation ! acr_values (optional) allows pass additional authentication related information user service - there values special meaning: idp:name_of_idp bypasses login/home realm screen and forwards user directly selected identity provider (if allowed per client configuration) tenant:name_of_tenant can used pass tenant name user service how p

UIPickerView Width in iOS8 Swift -

i can not find out how width of component on uipickerview. it's not allowing simple (int) needs cgfloat. put in <#code#> section? func pickerview(pickerview: uipickerview, widthforcomponent component: int) -> cgfloat { <#code#> } thank you! that method. doesn't "get width of component..." picker view calls method ask how wide component should be. your method simple as: func pickerview(pickerview: uipickerview, widthforcomponent component: int) -> cgfloat { return cgfloat(25.0) } (or whatever width appropriate picker view...) you need cast result exptected type.

What is the significance of this JavaScript code? -

what think doing looking see if object has been instantiated , exists within scope? why need use triple equal sign determine? function viewmodel(parent) { if (false === (this instanceof viewmodel)) { return new viewmodel(parent); } }; you don't need strict equality comparison there. instanceof yields true or false , entirely sufficient: if (!(this instanceof viewmodel))

c - Issue in passing a structure to a function accepting void * parameter -

i want call function of type foo(void * data) having input parameter struct variable. i have heard when input format of type void, accepts every type of input variable type. nevertheless, error message. struct info{ int element; }; struct info inserter_info; inserter_info.element = 0; inserter(inserter_info); where inserter() prototyped void * inserter(void * data) . i tried casting got error messages. i have heard when input format of type void, accepts every type of input variable type absolutely wrong !!! void means nothing . accepts nothing. however, void * considered generic pointer. quote c11 standard document, chapter 6.3.2.3, pointers, paragaraph 1, a pointer void may converted or pointer object type. pointer object type may converted pointer void , again; result shall compare equal original pointer. using attribute, many times, function parameter written void * that, function can accept different types of pointer , then, insi

c++ - Returning multiple arguments from an overloaded operator -

i may not doing correctly possible multiple return values overload? using overload compare between objects in binary search tree. i have 5 of them, post 2 (they similar anyways). bool extpersontype::operator > (extpersontype bob){ return (this->getlastname() > bob.getlastname()); //return (getdate().getmonth() > bob.getdate().getmonth()); //return (this->getstatus() > bob.getstatus()); } bool extpersontype::operator==(extpersontype bob){ return (this->getlastname() == bob.getlastname()); //return (getdate().getmonth() == bob.getdate().getmonth()); //return (this->getstatus() == bob.getstatus()); } so have 3 functions compare objects of "extpersontype" in bst. tried saw examples no luck (the output spits out randomly , data doesn't make sense). bool extpersontype::operator > (extpersontype bob){ return (this->getlastname() > bob.getlastname() && getdate().getmonth()

How linux device drivers are loaded? -

can explain me in simple terms following thing. how linux drivers loaded kernel space? functions exported, after drivers being loaded? how driver functions called? normally use insmod or modprobe userspace application load module (and possibly dependencies in case of 2nd one). both of them same under hood load single module - read file memory , use init_module system call, providing address of memory module loaded. call tells kernel module should loaded. now kernel modules elf files , not different shared libraries used in userspace. kernel has equivalent of shared library linker, parse files, list of symbols provided it, updating list of functions known kernel. check if symbols module needs in kernel , proper relocations. 1 of last thing call initialization function in module. note cannot compile kernel directly call function provided module. similarly, can call function provided module in module before loading first one. kernel refuse load module symbols not known
