/**

 * 1) This class does not support APOP authentication.
 * 2) Opening and closing lots of POP3 connections can be quite slow. If you need
 *   to send a batch of emails then just perform the authentication once at the start,
 *   and then loop through your mail sending script. Providing this process doesn't
 *   take longer than the verification period lasts on your POP3 server, you should be fine.
 * 3) This is really ancient technology; you should only need to use it to talk to very old systems.
 * 4) This POP3 class is deliberately lightweight and incomplete, implementing just
 *   enough to do authentication.
 *   If you want a more complete class there are other POP3 classes for PHP available.

/**
 * Guid represents a UUID with "native" (little-endian) byte order
 *
 * From Wikipedia:
 *
 * > The first three fields are unsigned 32- and 16-bit integers and are subject
 * > to swapping, while the last two fields consist of uninterpreted bytes, not
 * > subject to swapping. This byte swapping applies even for versions 3, 4, and
 * > 5, where the canonical fields do not correspond to the content of the UUID.
 *
 * The first three fields of a GUID are encoded in little-endian byte order,
 * while the last three fields are in network (big-endian) byte order. This is
 * according to the history of the Microsoft definition of a GUID.
 *
 * According to the .NET Guid.ToByteArray method documentation:
 *
 * > Note that the order of bytes in the returned byte array is different from
 * > the string representation of a Guid value. The order of the beginning
 * > four-byte group and the next two two-byte groups is reversed, whereas the
 * > order of the last two-byte group and the closing six-byte group is the
 * > same.

 * The CombGenerator, when used with the StringCodec (and, by proxy, the
 * TimestampLastCombCodec) or the TimestampFirstCombCodec, combines the current
 * timestamp with a UUID (hence the name "COMB"). The timestamp either appears
 * as the first or last 48 bits of the COMB, depending on the codec used.
 *
 * By default, COMBs will have the timestamp set as the last 48 bits of the
 * identifier.
 *
 * ``` php
 * $factory = new UuidFactory();
 *
 * $factory->setRandomGenerator(new CombGenerator(
 *     $factory->getRandomGenerator(),
 *     $factory->getNumberConverter()
 * ));
 *
 * $comb = $factory->uuid4();
 * ```
 *
 * To generate a COMB with the timestamp as the first 48 bits, set the
 * TimestampFirstCombCodec as the codec.
 *
 * ``` php
 * $factory->setCodec(new TimestampFirstCombCodec($factory->getUuidBuilder()));
 * ```

/**
 * 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 collection represents a group of objects.

 * Each object in the collection is of a specific, defined type.

 *
 * 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

 *
 * ``` php
 * namespace My\Foo;
 *
 * class FooCollection extends \Ramsey\Collection\AbstractCollection
 * {
 *     public function getType()
 *     {

 * ``` 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

 *
 * ``` php
 * if ($collection instanceof \My\Foo\FooCollection) {
 *     // the collection is a collection of My\Foo objects

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

 * <tr>
 * <th>Insert</th>
 * <td><code>add()</code></td>
 * <td><code>offer()</code></td>

 * <td><code>poll()</code></td>
 * </tr>
 * <tr>
 * <th>Examine</th>
 * <td><code>element()</code></td>
 * <td><code>peek()</code></td>
 * </tr>
 * </tbody>
 * </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.
