/**
 * Represents a single database table.
 *
 * Exposes methods for retrieving data out of it, and manages the associations
 * this table has to other tables. Multiple instances of this class can be created
 * for the same database table with different aliases, this allows you to address
 * your database structure in a richer and more expressive way.
 *
 * ### Retrieving data
 *
 * The primary way to retrieve data is using Table::find(). See that method
 * for more information.
 *
 * ### Dynamic finders
 *
 * In addition to the standard find($type) finder methods, CakePHP provides dynamic
 * finder methods. These methods allow you to easily set basic conditions up. For example
 * to filter users by username you would call
 *
 * ```
 * $query = $users->findByUsername('mark');
 * ```
 *
 * You can also combine conditions on multiple fields using either `Or` or `And`:
 *
 * ```
 * $query = $users->findByUsernameOrEmail('mark', 'mark@example.org');
 * ```
 *
 * ### Bulk updates/deletes
 *
 * You can use Table::updateAll() and Table::deleteAll() to do bulk updates/deletes.
 * You should be aware that events will *not* be fired for bulk updates/deletes.
 *
 * ### Callbacks/events
 *
 * Table objects provide a few callbacks/events you can hook into to augment/replace
 * find operations. Each event uses the standard event subsystem in CakePHP
 *
 * - `beforeFind(Event $event, Query $query, ArrayObject $options, boolean $primary)`
 *   Fired before each find operation. By stopping the event and supplying a
 *   return value you can bypass the find operation entirely. Any changes done
 *   to the $query instance will be retained for the rest of the find. The
 *   $primary parameter indicates whether or not this is the root query,
 *   or an associated query.
 *
 * - `buildValidator(Event $event, Validator $validator, string $name)`
 *   Allows listeners to modify validation rules for the provided named validator.
 *
 * - `buildRules(Event $event, RulesChecker $rules)`
 *   Allows listeners to modify the rules checker by adding more rules.
 *
 * - `beforeRules(Event $event, Entity $entity, ArrayObject $options, string $operation)`
 *   Fired before an entity is validated using the rules checker. By stopping this event,
 *   you can return the final value of the rules checking operation.
 *
 * - `afterRules(Event $event, Entity $entity, ArrayObject $options, bool $result, string $operation)`
 *   Fired after the rules have been checked on the entity. By stopping this event,
 *   you can return the final value of the rules checking operation.
 *
 * - `beforeSave(Event $event, Entity $entity, ArrayObject $options)`
 *   Fired before each entity is saved. Stopping this event will abort the save
 *   operation. When the event is stopped the result of the event will be returned.
 *
 * - `afterSave(Event $event, Entity $entity, ArrayObject $options)`
 *   Fired after an entity is saved.
 *
 * - `beforeDelete(Event $event, Entity $entity, ArrayObject $options)`
 *   Fired before an entity is deleted. By stopping this event you will abort
 *   the delete operation.
 *
 * - `afterDelete(Event $event, Entity $entity, ArrayObject $options)`
 *   Fired after an entity has been deleted.
 *
 * @see \Cake\Event\EventManager for reference on the events system.

     * ### Options
     *
     * The options array can receive the following keys:
     *
     * - atomic: Whether to execute the save and callbacks inside a database
     *   transaction (default: true)
     * - checkRules: Whether or not to check the rules on entity before saving, if the checking
     *   fails, it will abort the save operation. (default:true)
     * - associated: If true it will save all associated entities as they are found
     *   in the passed `$entity` whenever the property defined for the association
     *   is marked as dirty. Associated records are saved recursively unless told
     *   otherwise. If an array, it will be interpreted as the list of associations
     *   to be saved. It is possible to provide different options for saving on associated
     *   table objects using this key by making the custom options the array value.
     *   If false no associated records will be saved. (default: true)
     * - checkExisting: Whether or not to check if the entity already exists, assuming that the
     *   entity is marked as not new, and the primary key has been set.
     *
     * ### Events
     *
     * When saving, this method will trigger four events:
     *
     * - Model.beforeRules: Will be triggered right before any rule checking is done
     *   for the passed entity if the `checkRules` key in $options is not set to false.
     *   Listeners will receive as arguments the entity, options array and the operation type.
     *   If the event is stopped the checking result will be set to the result of the event itself.
     * - Model.afterRules: Will be triggered right after the `checkRules()` method is
     *   called for the entity. Listeners will receive as arguments the entity,
     *   options array, the result of checking the rules and the operation type.
     *   If the event is stopped the checking result will be set to the result of
     *   the event itself.
     * - Model.beforeSave: Will be triggered just before the list of fields to be
     *   persisted is calculated. It receives both the entity and the options as
     *   arguments. The options array is passed as an ArrayObject, so any changes in
     *   it will be reflected in every listener and remembered at the end of the event
     *   so it can be used for the rest of the save operation. Returning false in any
     *   of the listeners will abort the saving process. If the event is stopped
     *   using the event API, the event object's `result` property will be returned.
     *   This can be useful when having your own saving strategy implemented inside a
     *   listener.
     * - Model.afterSave: Will be triggered after a successful insert or save,
     *   listeners will receive the entity and the options array as arguments. The type
     *   of operation performed (insert or update) can be determined by checking the
     *   entity's method `isNew`, true meaning an insert and false an update.
     *
     * This method will determine whether the passed entity needs to be
     * inserted or updated in the database. It does that by checking the `isNew`
     * method on the entity. If the entity to be saved returns a non-empty value from
     * its `errors()` method, it will not be saved.
     *
     * ### Saving on associated tables
     *
     * This method will by default persist entities belonging to associated tables,
     * whenever a dirty property matching the name of the property name set for an
     * association in this table. It is possible to control what associations will
     * be saved and to pass additional option for saving them.
     *
     * ```
     * // Only save the comments association
     * $articles->save($entity, ['associated' => ['Comments']);
     *
     * // Save the company, the employees and related addresses for each of them.
     * // For employees do not check the entity rules
     * $companies->save($entity, [
     *   'associated' => [
     *     'Employees' => [
     *       'associated' => ['Addresses'],
     *       'checkRules' => false
     *     ]
     *   ]
     * ]);

     * $articles->save($entity, ['associated' => false]);
