is there wrong design point of view having global object returns singletons spring context? i started work @ new place, , daos accessed via global object called daoutils, each dao gets singleton dao bean spring context. if want save purchase order, example, say daoutils.getpurchaseorderdao().savepurchaseorder(po); or that. i've been used injecting daos required each class needs them, , shocked me little. there wrong design point of view, , if can explain why bad idea? i can see makes unit testing difficult, because there's no way stop code calling actual daoutils class..? guess described problem caused tight coupling? this bad design pattern since cannot substitute daoutils else e.g. testing purposes. spring uses dependency injection , that's best way retrieve dao instance.

i'm looking pythonic solution on how store method called on object right inside object. because in python, if want catch example abs() method, overload operator like: catcher(object): def __abs__(self): self.function = abs c = catcher() abs(c) # c.function stores 'abs' called on c if want catch function, have other attribute in it, example pow() , i'm going use this: catcher(object): def __pow__(self, value): self.function = pow self.value = value c = catcher() c ** 2 # c.function stores 'pow', , c.value stores '2' now, i'm looking general solution, catch , store kind of function called on catcher , without implementing overloads, , other cases. , can see, want store values ( maybe in list, if there more 1 of them? ) attributes of method. thanks in advance! a metaclass won't here; although special methods looked on type of current object (so class instances), __getattribute__ or __get

how can send/passing local variable in procedure procedure in delphi? procedure tform1.button1click(sender: tobject); var a,b:integer; c: array [o..3] smallint; begin a:=1; b:=2; end; i want send 1 or more local variable(a,b,c) has value procedure use them there like: procedure tform1.button2click(sender: tobject); var d:integer; begin d:=a*b; end; i want send 1 or more local variable(a,b,c) has value procedure use them there. this shows misunderstanding lifetime of local variables. local variables have scope duration of function owns them. since 2 event handlers have disjoint lifetimes, local variables never in existence simultaneously. so when "that has value", mistaken. local variables exist when button1click executing not exist when button2click executing. you'd need variables members of class rather local variables. way variables' lifetimes span separate execution of event handlers. type tform1 = class(tform) .... pr

i'm trying change colour of datagrid cell based on if it's min or max value in observablecollection value of cell part of. now have following datagrid , style template: <grid itemssource="{binding mydata.myobscollection}"> <datagrid.resources> <style targettype="{x:type datagridcell}"> <setter property="foreground"> <setter.value> <multibinding converter="{staticresource myvalidconverter}"> <binding path="mdtime" /> //myobscollection doesn't work here <binding path="mdisvalid" /> </multibinding> </setter.value> </setter> </style>... the collection, simplified, consists of following: public class myclass : inotifypropertychanged { ... public observablecollection<mydata> myobscollection { get; set

i able plot date against price, date on x-axis , price shown in y-axis. later want plot volume-date graph in same chart, i've used combinedrangexyplot purpose. common data here both graphs date. ideally want graphs displayed 1 below other (horizontal orientation) common x-axis being date , each having own y-axis, 1 being price , other being volume but issue facing is, when orientation horizontal dates displayed in y-axis graphs appeared tilted @ 90 degree angle. if orientation vertical, x-axis consists of dates , y-axis handles both price , volume. since price movement in 100's , volume movement in millions, not able spot price movements in graph. ideally want x-axis common both graphs containing dates when orientation horizontal, require 2 y-axis values 1 each graph. final xyplot priceplot = new xyplot(dataset, new dateaxis("date"), null, new standardxyitemrenderer()); numberaxis numberaxis = (numberaxis)priceplot.getrangeaxis(); numberaxis.setr

currently have following code: //loop here foreach ($doc['a'] $link) { $href = pq($link)->attr('href'); if (preg_match($url,$href)) { //delete matched string , append custom url href attr } else { //prepend custom url href attr } } //end loop basically i've fetched vial curl external page. need append own custom url each href link in dom. need check via regex if each href attr has base url e.g. www.domain.com/mainpage.html/subpage.html if yes, replace www.domain.com part custom url. if not, append custom url relative url. my question is, regex syntax should use , php function? preg_replace() proper function this? cheers you should use internals opposed regex whenever possible, because authors of functions have considered edge cases (or read really long rfc urls details of cases). case, use parse_url() , http_build_
