javascript - dojo wrapper or adapter classes -

-

i have started using dojo, wondering if there anyway implement wrapper/adapter class. in pure javascript following

function person(name){     this.name=name; }  function employee(name,id){     this.person=person;     this.person(name);     this.id=id;      this.promotedemployee=promotedemployee; }  function promotedemployee(employees){     this.employees=employees;  //number of people working him/her }  var employee=new employee("john stamos",123); employee.promotedemployee(10);   //promote manage 10 people

how do dojo. such not work

dojo.declare("person",null,{     constructor: function(name){         this.name=name;     } });  dojo.declare("promotedemployee",null,{     constructor: function(employees){         this.employees=employees;     } });  dojo.declare("employee",[person],{     constructor: function(name,id){         this.id=id;     },     promotedemployee=promotedemployee; });  var employee=new employee("john stamos",123); employee.promotedemployee(10);   //promote manage 10 people 

dojo.declare("promotedemployee",null,{     employees: 0,     constructor: function(){      },     promoteemployees: function(employees){          this.employees = employees;     } }); dojo.declare("employee",[person],{     constructor: function(name,id){         this.id=id;         this.promotedemployee = new promotedemployee();     } });  var employee=new employee("john stamos",123); employee.promotedemployee.promoteemployees(10);

//or

dojo.declare("promotedemployee",null,{         constructor: function(employees){            this.employees = employees;         }     });     dojo.declare("employee",[person],{         constructor: function(name,id,employees){             this.id=id;             this.promotedemployee = new promotedemployee(employees);         }     });      var employee=new employee("john stamos",123, 10);  //alert(employee.promotedemployee.employees);

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
