i'm making game in java need character listen on time event handled in class. i been using this answer make own listener it. so fare have defined interface this: public interface timelistener { public void ontick(timeevent event); } and the timeevent this: public class timeevent { private int time; public timeevent(int time) { this.time = time; } public int gettime() { return time; } } in answer wrote eatevent simple wrapper class food. not quite how that. timeevent cover this? my timeevent, unlike eatevent, needs give time along time class listeners. proper way send time along? simply use observer design pattern it

python uses pythonpath environment-variable determine in folders should modules. can play around modifying sys.path , works nicely pure python-modules. when module uses shared object files or static libraries, looks in ld_library_path (on linux), can't changed , platform dependent far know. the quick-fix problem of course set environment-variable or invoke script ld_library_path=. ./script.py , you'll have set again every new shell open. also, .so files in case in same directory .py file, may moved absolute path, i'd set them automatically every time invoke script. how can edit path in python interpreter looks libraries platform-independently on runtime? edit: i tried os.environ['ld_library_path'] = os.getcwd() , no avail. i use: import os os.environ['ld_library_path'] = os.getcwd() # or whatever path want this sets ld_library_path environment variable duration/lifetime of execution of current process only. edit: looks need

suppose have following code a<-c(1,2,3) b<-'a' now treat string in 'b' variable 'a' when input function or operation. imagine "treat.as.variable()" real function this: treat.as.variable(b)+c(1,2,4) [1] 2 4 7 is there function this, predefined? or way in general? use get function > get(b) + c(1,2,4) [1] 2 4 7

i working on xml using fhir resource. found element of resource cross reference other resources. e.g. in encounter (resource), element :serviceprovider cross reference resource(organization). in such case, there way specify elements of resource(organization) on encounter (resource) xml such can validated correctly? i think you're asking is: can constrain information care have captured organization associated encounter (as opposed organization communicated in other manner or context). example, encounter, might want name , phone number while in other contexts may want other information. if that's indeed you're looking for,, solution profile. create profile on encounter and, serviceprovider reference organization, on "type" element, in addition "code" element indicating "organization", you'd specify "profile" element pointing structure wanted enforced on content of organization. structure might defined in same

my application under test has been developed external suppliers have no control on html structure. application extremely javascript , ajax heavy, numerous dynamically generated buttons , auto-complete lists. in other words, characteristics of pages filled with: elements no fixed ids (ids generated on fly , have numbers or other text dynamically added them) the same happens classes most of times buttons have no text associated them since either custom coded 'down' arrows lookup lists (which aren't lookup lists hidden divs) or '+' , '-' icons maximise or minimise portions of content. - it therefore difficult identify these elements, buttons. i trying write generic 'i click on button near y' type of step not necessary hardcode each , every button (assuming can identify them with) each , every test. the thinking behind there label of sort close button @ least. what want to find text label, see if there button inside same scope, , if t
