repeat

I want to dynamically add triggers to a job, but can't find any helpful methods off of Scheduler I though i would just be able to call the scheduleJob method an repetitively, but this gives me tthe ObjectAlreadyExists Exception "because one already exists with this identification". How can i do this? EDIT private boolean scheduleLoadJob( XfuScheduleTimeInfo time ) { LoadScheduleJob job = new LoadScheduleJob( time ); JobDetail detail; Integer id = Integer.valueOf( time.getScheduleId() ); if( _hashMap.containsKey( id ) ) { detail = _hashMap.get( Integer.valueOf( time.getScheduleId() ) ); } else

I want to allocate a new array with the length N and fill it up by repeating a given array. The interface looks like this: <T> T[] repeat(T[] array, int n); To clarify what I mean here is a small example: String a = {"a", "b", "c"}; // b = {"a", "b", "c", "a", "b", "c", "a", "b", "c", "a"} String b = repeat(a, 10); Most of the programmer will come up with the following solution (for simplicity of array generation a specific type was chosen): public String[] repeat(String[] array, int n) { String[] repeated = new String[n]; for (int i = 0; i < n; i++) { repeated[i] = array[i % array.length]; }

I am Peter Pilgrim. I watched Martin Odersky create a control abstraction in Scala. However I can not yet seem to repeat it inside IntelliJ IDEA 9. Is it the IDE? package demo class Control { def repeatLoop ( body: => Unit ) = new Until( body ) class Until( body: => Unit ) { def until( cond: => Boolean ) { body; val value: Boolean = cond; println("value="+value) if ( value ) repeatLoop(body).until(cond) // if (cond) until(cond) } } def doTest2(): Unit = { var y: Int = 1 println("testing ... repeatUntil() control structure") repeatLoop { println("found y="+y) y = y + 1 } { until ( y < 10 ) } }

I'm trying to perform auto repeat of my image rotation animation with CABasicAnimation. I have tried to search on web how to set such property but was unable to find that. Is it really no such property for CA animation? I know that you can set some huge value ( here ) to repeatCount property but hey, why then does UIView animateWithDuration has an option UIViewAnimationOptionRepeat and what the value is hardcoded for it? No, this is the way you're supposed to do it according to the documentation . Setting this property to HUGE_VALF will cause the animation to repeat forever. Update for Swift:

In Ruby I could repeat a String n times with the following: E.G. "my_string" * 2 -> "my_stringmy_string" Is there an equally simple way for doing this in R? You can use replicate or rep : replicate(2, "my_string") # [1] "my_string" "my_string" rep("my_string", 2) # [1] "my_string" "my_string" paste will put it together: paste(replicate(2, "my_string"), collapse = "") # [1] "my_stringmy_string" With R 3.3.0 , we can use strrep from base R strrep("my_string",2) #[1] "my_stringmy_string" We can also pass a vector of values in times strrep("my_string",1:3) #[1] "my_string" "my_stringmy_string" #[3
