The only requirement for an object to be initialized using this syntactic sugar is that the type implements System.Collections.IEnumerable and the Add method. Although we call it a collection initializer, the object does not have to be an collection.

There are several kinds of collection: Array List Queue SortedList Stack Dictionary

The collections framework in java.util provides a number of generic classes for sets of data with functionality that can't be provided by regular arrays. Collections framework contains interfaces for Collection<O>, with main sub-interfaces List<O> and Set<O>, and mapping collectio...

The built-in collections package provides several specialized, flexible collection types that are both high-performance and provide alternatives to the general collection types of dict, list, tuple and set. The module also defines abstract base classes describing different types of collection functi...

'() → () '(1 2 3 4 5) → (1 2 3 4 5) '(1 foo 2 bar 3) → (1 'foo 2 'bar 3) (list 1 2 3 4 5) → (1 2 3 4 5) (list* [1 2 3 4 5]) → (1 2 3 4 5) [] → [] [1 2 3 4 5] → [1 2 3 4 5] (vector 1 2 3 4 5) → [1 2 3 4 5] (vec '(1 2 3 4 5)) → [1 2 3 4 5] {} => {} {:keyA 1 :keyB 2} → {:keyA 1 :keyB 2} ...

$collection = collect(['Value1', 'Value2', 'Value3']); // Keys default to 0, 1, 2, ..., Illuminate\Support\Collection provides a fluent and convenient interface to deal with arrays of data. You may well have used these without knowing, for instance Model queries that fetch multiple records...

At its core, Python's garbage collector (as of 3.5) is a simple reference counting implementation. Every time you make a reference to an object (for example, a = myobject) the reference count on that object (myobject) is incremented. Every time a reference gets removed, the reference count is dec...

This topic about Java collections from guava, apache, eclipse: Multiset, Bag, Multimap, utils function from this lib and so on.

Parallel collections facilitate parallel programming by hiding low-level parallelization details. This makes taking advantage of multi-core architectures easy. Examples of parallel collections include ParArray, ParVector, mutable.ParHashMap, immutable.ParHashMap, and ParRange. A full list can be f...

A useful way to think about Mongo collections is in terms of Who, What, When, Where, Why, and How. Mongo has the following optimizations for different types of data: Where - GeoJSON When - ObjectID timestamps Who - Meteor Account Strings How - JSON for decision trees Which leaves the default...

A Collection is a container object that is included in the VBA runtime. No additional references are required in order to use it. A Collection can be used to store items of any data type and allows retrieval by either the ordinal index of the item or by using an optional unique key. Feature C...
