Method Detail
__construct() ¶ public
__construct(array|null $locations = null)Constructor.
Parameters
-
array|null$locations optional Locations where tables should be looked for. If none provided, the default
Model\Tableunder your app's namespace is used.
_create() ¶ protected
_create(array $options): Cake\ORM\TableWrapper for creating table instances
Parameters
-
array$options The alias to check for.
Returns
Cake\ORM\Table_getClassName() ¶ protected
_getClassName(string $alias, array $options = []): string|falseGets the table class name.
Parameters
-
string$alias The alias name you want to get.
-
array$options optional Table options array.
Returns
string|falseaddLocation() ¶ public
addLocation(string $location): $thisAdds a location where tables should be looked for.
Parameters
-
string$location Location to add.
Returns
$thisconfig() ¶ public
config(string|null $alias = null, array|null $options = null): arrayStores a list of options to be used when instantiating an object with a matching alias.
The options that can be stored are those that are recognized by get()
If second argument is omitted, it will return the current settings
for $alias.
If no arguments are passed it will return the full configuration array for all aliases
Parameters
-
string|null$alias optional Name of the alias
-
array|null$options optional list of options for the alias
Returns
arrayThrows
RuntimeExceptionWhen you attempt to configure an existing table instance.
exists() ¶ public
exists(string $alias): boolCheck to see if an instance exists in the registry.
Parameters
-
string$alias
Returns
boolgenericInstances() ¶ public
genericInstances(): Cake\ORM\Table[]Returns the list of tables that were created by this registry that could not be instantiated from a specific subclass. This method is useful for debugging common mistakes when setting up associations or created new table classes.
Returns
Cake\ORM\Table[]get() ¶ public
get(string $alias, array $options = []): Cake\ORM\TableGet a table instance from the registry.
Tables are only created once until the registry is flushed. This means that aliases must be unique across your application. This is important because table associations are resolved at runtime and cyclic references need to be handled correctly.
The options that can be passed are the same as in Cake\ORM\Table::__construct(), but the
className key is also recognized.
Options
classNameDefine the specific class name to use. If undefined, CakePHP will generate the class name based on the alias. For example 'Users' would result inApp\Model\Table\UsersTablebeing used. If this class does not exist, then the defaultCake\ORM\Tableclass will be used. By setting theclassNameoption you can define the specific class to use. The className option supports plugin short class references {@link Cake\Core\App::shortName()}.tableDefine the table name to use. If undefined, this option will default to the underscored version of the alias name.connectionInject the specific connection object to use. If this option andconnectionNameare undefined, The table class'defaultConnectionName()method will be invoked to fetch the connection name.connectionNameDefine the connection name to use. The named connection will be fetched from Cake\Datasource\ConnectionManager.
Note If your $alias uses plugin syntax only the name part will be used as
key in the registry. This means that if two plugins, or a plugin and app provide
the same alias, the registry will only store the first instance.
Parameters
-
string$alias The alias name you want to get.
-
array$options optional The options you want to build the table with. If a table has already been loaded the options will be ignored.
Returns
Cake\ORM\TableThrows
RuntimeExceptionWhen you try to configure an alias that already exists.
getConfig() ¶ public
getConfig(mixed $alias = null): arrayReturns configuration for an alias or the full configuration array for all aliases.
Parameters
-
$alias optional Alias to get config for, null for complete config.
Returns
arrayremove() ¶ public
remove(string $alias): voidRemoves an instance from the registry.
Parameters
-
string$alias
Returns
voidset() ¶ public
set(string $alias, Cake\ORM\Table $object): Cake\ORM\TableSet an instance.
Parameters
-
string$alias -
Cake\ORM\Table$object
Returns
Cake\ORM\TablesetConfig() ¶ public
setConfig(mixed $alias, mixed $options = null): $thisStores a list of options to be used when instantiating an object with a matching alias.
