swift - How do you apply a predicate while traversing through a fulfilled NSManagedObject? -


i'm trying apply predicate while traversing through to-many relationship using nsmanagedobject has been fulfilled in context. thought casting set array , applying filter algorithm, trigger bunch of faults don't want there possibly 500+ objects in set. possible when accessing nsset of faults through nsmanagedobject can apply predicate or filter set , fulfill faults?

filtering objects in relationship correct. far more efficient doing separate fetch. have learned personal experience relationship size in same ballpark (100-2000 entities), , found around 10 fold speed difference between doing fetch vs filtering relationship.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
