i need azure service bus notify end point (rest - post) whenever message comes particular topic. in aws, done way aws llink what equivalent in azure. note: dont want write code receive message , call end point. azure service bus messaging service, not notifications service. such, deals solely messaging, , doesn't create notifications you. aws combines sqs (simple queuing service) sns (simple notification service) behind scenes allow functionality you're describing. allow sqs have behaviour of events. azure service bus has native support topics , subscriptions (if that's you're looking for). i.e. rather sending messages queue, message sent topic , appropriate subscriber(s) it. so short answer question in case don't want receive message , trigger notification "no". saying that, if you're ok "serverless" functions (similar aws lambdas), use azure functions achieve goal.

so i'm building data hub. want store large amounts of data in database. in order there these pipes of data data providers have make using apis. i want secure apis know who's making streams , can limit makes them. can send them. make sense oauth non-ingestion api methods , use api key ingestion methods? oauth tokens tend expire , ingestion of data long running process. doesn't feel right solution since there's 2 separate security protocols being used. the other option see right force users check expiration time of tokens , try refresh them if it's expire , still need send data. oauth 2.0 allows clients long-running offline processes via usage of refresh token allows client new access token when current 1 expires. user doesn't need involved since proper oauth 2.0 client should able deal expired tokens on own.

(ps: not objc, focused on swift) note error mentions "forward class object 'cllocation'". this means use @class cllocation somewhere (probably in .h file). doesn't provide details cllocation other class. to fix code need import proper .h file in .m file tries access properties of clloca...

i have directory structure this: file1.txt file2.txt dir1/ file3.txt file4.txt i want use gradle copy entire structure directory. tried this: task mytest << { copy { "file1.txt" "file2.txt" "dir1" "mytest" } } but results in following: mytest/ file1.txt file2.txt file3.txt file4.txt see, copy dir1 copied files in dir1 , whereas want copy dir1 itself . is possible directly gradle copy ? so far, have been able come solution: task mytest << { copy { "file1.txt" "file2.txt" "mytest" } copy { "dir1" "mytest/dir1" } } for simple example there's not it, in actual case there many directories want copy, , i'd not have repeat much. you can use . directory path , include specify, files , directories want copy: copy { '....

pardon me if stupid question.. wondering if there support following comparison in java: (a, b, c .... != null) in place : (a != null && b != null && c != null && d ! null , on ..) i trying make code more readable code unreadable due multiple condition in single statement. code : variable = (rest.host != null && rest.payload != null && rest.lockqueue != null && rest.endpoint != null ) || rest.default.setstate || rest.scheduler.locked && rest.scheduler.queue.isfull() && lastpayload.getactivity.status.executing ? onexecute(rest.payload) : wait(time); if elements in collection, use collection.stream().allmatch(x -> x != null) . actually, there's predicate that: collection.stream().allmatch(objects::nonnull) . if elements aren't in collection, can still use arrays.aslist() create ad-hoc list them. so, in case: arrays.aslist(rest.host, rest.payload, rest.lockqueue, rest.en...
