+ * A collection represents a group of objects.
+ *
+ * Each object in the collection is of a specific, defined type.
+ *
+ * This is a direct implementation of `CollectionInterface`, provided for
+ * the sake of convenience.
+ *
+ * Example usage:
+ *
+ * ``` php
+ * $collection = new \Ramsey\Collection\Collection('My\\Foo');
+ * $collection->add(new \My\Foo());
+ * $collection->add(new \My\Foo());
+ *
+ * foreach ($collection as $foo) {
+ *     // Do something with $foo
+ * }
+ * ```
+ *
+ * It is preferable to subclass `AbstractCollection` to create your own typed
+ * collections. For example:
+ *
+ * ``` php
+ * namespace My\Foo;
+ *
+ * class FooCollection extends \Ramsey\Collection\AbstractCollection
+ * {
+ *     public function getType()
+ *     {
+ *         return 'My\\Foo';
+ *     }
+ * }
+ * ```
+ *
+ * And then use it similarly to the earlier example:
+ *
+ * ``` php
+ * $fooCollection = new \My\Foo\FooCollection();
+ * $fooCollection->add(new \My\Foo());
+ * $fooCollection->add(new \My\Foo());
+ *
+ * foreach ($fooCollection as $foo) {
+ *     // Do something with $foo
+ * }
+ * ```
+ *
+ * The benefit with this approach is that you may do type-checking on the
+ * collection object:
+ *
+ * ``` php
+ * if ($collection instanceof \My\Foo\FooCollection) {
+ *     // the collection is a collection of My\Foo objects

+/**
+ * A linear collection that supports element insertion and removal at both ends.
+ *
+ * Most `DoubleEndedQueueInterface` implementations place no fixed limits on the
+ * number of elements they may contain, but this interface supports
+ * capacity-restricted double-ended queues as well as those with no fixed size
+ * limit.
+ *
+ * This interface defines methods to access the elements at both ends of the
+ * double-ended queue. Methods are provided to insert, remove, and examine the
+ * element. Each of these methods exists in two forms: one throws an exception
+ * if the operation fails, the other returns a special value (either `null` or
+ * `false`, depending on the operation). The latter form of the insert operation
+ * is designed specifically for use with capacity-restricted implementations; in
+ * most implementations, insert operations cannot fail.
+ *
+ * The twelve methods described above are summarized in the following table:
+ *
+ * <table>
+ * <caption>Summary of DoubleEndedQueueInterface methods</caption>
+ * <thead>
+ * <tr>
+ * <th></th>
+ * <th colspan=2>First Element (Head)</th>
+ * <th colspan=2>Last Element (Tail)</th>
+ * </tr>
+ * <tr>
+ * <td></td>
+ * <td><em>Throws exception</em></td>
+ * <td><em>Special value</em></td>
+ * <td><em>Throws exception</em></td>
+ * <td><em>Special value</em></td>
+ * </tr>
+ * </thead>
+ * <tbody>
+ * <tr>
+ * <th>Insert</th>
+ * <td><code>addFirst()</code></td>
+ * <td><code>offerFirst()</code></td>
+ * <td><code>addLast()</code></td>
+ * <td><code>offerLast()</code></td>
+ * </tr>
+ * <tr>
+ * <th>Remove</th>
+ * <td><code>removeFirst()</code></td>
+ * <td><code>pollFirst()</code></td>
+ * <td><code>removeLast()</code></td>
+ * <td><code>pollLast()</code></td>
+ * </tr>
+ * <tr>
+ * <th>Examine</th>
+ * <td><code>firstElement()</code></td>
+ * <td><code>peekFirst()</code></td>
+ * <td><code>lastElement()</code></td>
+ * <td><code>peekLast()</code></td>
+ * </tr>
+ * </tbody>
+ * </table>
+ *
+ * This interface extends the `QueueInterface`. When a double-ended queue is
+ * used as a queue, FIFO (first-in-first-out) behavior results. Elements are
+ * added at the end of the double-ended queue and removed from the beginning.
+ * The methods inherited from the `QueueInterface` are precisely equivalent to
+ * `DoubleEndedQueueInterface` methods as indicated in the following table:
+ *
+ * <table>
+ * <caption>Comparison of QueueInterface and DoubleEndedQueueInterface methods</caption>
+ * <thead>
+ * <tr>
+ * <th>QueueInterface Method</th>
+ * <th>DoubleEndedQueueInterface Method</th>
+ * </tr>
+ * </thead>
+ * <tbody>
+ * <tr>
+ * <td><code>add()</code></td>
+ * <td><code>addLast()</code></td>
+ * </tr>
+ * <tr>
+ * <td><code>offer()</code></td>
+ * <td><code>offerLast()</code></td>
+ * </tr>
+ * <tr>
+ * <td><code>remove()</code></td>
+ * <td><code>removeFirst()</code></td>
+ * </tr>
+ * <tr>
+ * <td><code>poll()</code></td>
+ * <td><code>pollFirst()</code></td>
+ * </tr>
+ * <tr>
+ * <td><code>element()</code></td>
+ * <td><code>firstElement()</code></td>
+ * </tr>
+ * <tr>
+ * <td><code>peek()</code></td>
+ * <td><code>peekFirst()</code></td>
+ * </tr>
+ * </tbody>
+ * </table>
+ *
+ * Double-ended queues can also be used as LIFO (last-in-first-out) stacks. When
+ * a double-ended queue is used as a stack, elements are pushed and popped from
+ * the beginning of the double-ended queue. Stack concepts are precisely
+ * equivalent to `DoubleEndedQueueInterface` methods as indicated in the table
+ * below:
+ *
+ * <table>
+ * <caption>Comparison of stack concepts and DoubleEndedQueueInterface methods</caption>
+ * <thead>
+ * <tr>
+ * <th>Stack concept</th>
+ * <th>DoubleEndedQueueInterface Method</th>
+ * </tr>
+ * </thead>
+ * <tbody>
+ * <tr>
+ * <td><em>push</em></td>
+ * <td><code>addFirst()</code></td>
+ * </tr>
+ * <tr>
+ * <td><em>pop</em></td>
+ * <td><code>removeFirst()</code></td>
+ * </tr>
+ * <tr>
+ * <td><em>peek</em></td>
+ * <td><code>peekFirst()</code></td>
+ * </tr>
+ * </tbody>
+ * </table>
+ *
+ * Note that the `peek()` method works equally well when a double-ended queue is
+ * used as a queue or a stack; in either case, elements are drawn from the
+ * beginning of the double-ended queue.
+ *
+ * While `DoubleEndedQueueInterface` implementations are not strictly required
+ * to prohibit the insertion of `null` elements, they are strongly encouraged to
+ * do so. Users of any `DoubleEndedQueueInterface` implementations that do allow
+ * `null` elements are strongly encouraged *not* to take advantage of the
+ * ability to insert nulls. This is so because `null` is used as a special
+ * return value by various methods to indicated that the double-ended queue is
+ * empty.

+/**
+ * A `TypedMap` represents a map of elements where key and value are typed.
+ *
+ * Each element is identified by a key with defined type and a value of defined
+ * type. The keys of the map must be unique. The values on the map can be=
+ * repeated but each with its own different key.
+ *
+ * The most common case is to use a string type key, but it's not limited to
+ * this type of keys.
+ *
+ * This is a direct implementation of `TypedMapInterface`, provided for the sake
+ * of convenience.
+ *
+ * Example usage:
+ *
+ * ```php
+ * $map = new TypedMap('string', Foo::class);
+ * $map['x'] = new Foo();
+ * foreach ($map as $key => $value) {
+ *     // do something with $key, it will be a Foo::class
+ * }
+ *
+ * // this will throw an exception since key must be string
+ * $map[10] = new Foo();
+ *
+ * // this will throw an exception since value must be a Foo
+ * $map['bar'] = 'bar';
+ *
+ * // initialize map with contents
+ * $map = new TypedMap('string', Foo::class, [
+ *     new Foo(), new Foo(), new Foo()
+ * ]);
+ * ```
+ *
+ * It is preferable to subclass `AbstractTypedMap` to create your own typed map
+ * implementation:
+ *
+ * ```php
+ * class FooTypedMap extends AbstractTypedMap
+ * {
+ *     public function getKeyType()
+ *     {
+ *         return 'int';
+ *     }
+ *
+ *     public function getValueType()
+ *     {
+ *          return Foo::class;
+ *     }
+ * }
+ * ```
+ *
+ * … but you also may use the `TypedMap` class:
+ *
+ * ```php
+ * class FooTypedMap extends TypedMap
+ * {
+ *     public function __constructor(array $data = [])
+ *     {
+ *         parent::__construct('int', Foo::class, $data);

+/**
+ * A queue is a collection in which the entities in the collection are kept in
+ * order.
+ *
+ * The principal operations on the queue are the addition of entities to the end
+ * (tail), also known as *enqueue*, and removal of entities from the front
+ * (head), also known as *dequeue*. This makes the queue a first-in-first-out
+ * (FIFO) data structure.
+ *
+ * Besides basic array operations, queues provide additional insertion,
+ * extraction, and inspection operations. Each of these methods exists in two
+ * forms: one throws an exception if the operation fails, the other returns a
+ * special value (either `null` or `false`, depending on the operation). The
+ * latter form of the insert operation is designed specifically for use with
+ * capacity-restricted `QueueInterface` implementations; in most
+ * implementations, insert operations cannot fail.
+ *
+ * <table>
+ * <caption>Summary of QueueInterface methods</caption>

+ * <tr>
+ * <td></td>
+ * <td><em>Throws exception</em></td>
+ * <td><em>Returns special value</em></td>

+ * </table>
+ *
+ * Queues typically, but do not necessarily, order elements in a FIFO
+ * (first-in-first-out) manner. Among the exceptions are priority queues, which
+ * order elements according to a supplied comparator, or the elements' natural
+ * ordering, and LIFO queues (or stacks) which order the elements LIFO
+ * (last-in-first-out). Whatever the ordering used, the head of the queue is
+ * that element which would be removed by a call to remove() or poll(). In a
+ * FIFO queue, all new elements are inserted at the tail of the queue. Other
+ * kinds of queues may use different placement rules. Every `QueueInterface`
+ * implementation must specify its ordering properties.
+ *
+ * The `offer()` method inserts an element if possible, otherwise returning
+ * `false`. This differs from the `add()` method, which can fail to add an
+ * element only by throwing an unchecked exception. The `offer()` method is
+ * designed for use when failure is a normal, rather than exceptional
+ * occurrence, for example, in fixed-capacity (or "bounded") queues.
+ *
+ * The `remove()` and `poll()` methods remove and return the head of the queue.
+ * Exactly which element is removed from the queue is a function of the queue's
+ * ordering policy, which differs from implementation to implementation. The
+ * `remove()` and `poll()` methods differ only in their behavior when the queue
+ * is empty: the `remove()` method throws an exception, while the `poll()`
+ * method returns `null`.
+ *
+ * The `element()` and `peek()` methods return, but do not remove, the head of
+ * the queue.
+ *
+ * `QueueInterface` implementations generally do not allow insertion of `null`
+ * elements, although some implementations do not prohibit insertion of `null`.
+ * Even in the implementations that permit it, `null` should not be inserted
+ * into a queue, as `null` is also used as a special return value by the
+ * `poll()` method to indicate that the queue contains no elements.
