i'm working kue workers set , have discovered strange. if create queue using default kue redis connection works perfectly: var kue = require('kue') , redis = require('redis'); var q = kue.createqueue(); q.process('cypher', function(job, done){}); the worker starts perfectly. however, if try override default redis connection 1 of own error: connection in subscriber mode, subscriber commands may used when execution hits q.process function below: var kue = require('kue') , redis = require('redis'); var redisclient = redis.createclient(); var q = kue.createqueue({ redis: { createclientfactory: function(){ return redisclient; } } }); q.process('cypher', function(job, done){}); it doesn't seem sense. thought maybe committing classic async error, following same error. any insights? redisclient.on('connect', function () { console.log('gotten here!!...

i make == generic function. when run: setgeneric("==") , definition not appear change: > `==` function (e1, e2) .primitive("==") > setgeneric("==") [1] "==" > `==` function (e1, e2) .primitive("==") and when call setgeneric("`==`") , following error: > setgeneric("`==`") error in setgeneric("`==`") : must supply function skeleton ‘`==`’, explicitly or via existing function i can define == function with: `==` <- function(x,y) 42; and can use setgeneric on it. i'd have put body of original == there, seems clunky. so there way make == generic in s4? thanks mrflick's response: it turns out == generic (implement in c). don't need call setgeneric . rather, can use setmethod . setmethod("==", c(e1="class1",e2="class2"), funciton(e1,e2) { .... })

this question has answer here: setup/teardown (@before/@after) why need them in junit? 6 answers being new junit have done far setting dependencies (i.e. creating objects) within test methods itself. questions: eclipse mocks unused variables, though. setup , teardown for? is practice create objects within setup , null them out via teardown ? what other use cases methods above? what purpose of working pre-suite setup , teardown . can give example when comes in handy? cheers, andrew being new junit have done far setting dependencies (i.e. creating objects) within test methods itself. if initialized , cleaned correctly there nothing wrong approach. have way, if different tests need different dependencies. eclipse mocks unused variables, though. setup , teardown for? unused variables have nothing setup , teardown methods. should eit...
