Trait StaticConfigTrait
A trait that provides a set of static methods to manage configuration for classes that provide an adapter facade or need to have sets of configuration data registered and manipulated.
Implementing objects are expected to declare a static $_dsnClassMap
property.

configsource public static
config( string|array $key , array $config null )
This method can be used to define configuration adapters for an application or read existing configuration.
To change an adapter's configuration at runtime, first drop the adapter and then reconfigure it.
Adapters will not be constructed until the first operation is done.
Usage
Assuming that the class' name is Cache
the following scenarios are supported:
Reading config data back:
Cache::config('default');
Setting a cache engine up.
Cache::config('default', $settings);
Injecting a constructed adapter in:
Cache::config('default', $instance);
Configure multiple adapters at once:
Cache::config($arrayOfConfig);
Parameters
- string|array
$key
- The name of the configuration, or an array of multiple configs.
- array
$config
optional null - An array of name => configuration data for adapter.
Returns
array|null
Null when adding configuration or an array of configuration data when reading.
Throws
BadMethodCallException
When trying to modify an existing config.
configuredsource public static
configured( )
Returns an array containing the named configurations
Returns
array
Array of configurations.
dropsource public static
drop( string $config )
Drops a constructed adapter.
If you wish to modify an existing configuration, you should drop it, change configuration and then re-add it.
If the implementing objects supports a $_registry
object the named configuration will also be unloaded from the registry.
Parameters
- string
$config
- An existing configuration you wish to remove.
Returns
boolean
Success of the removal, returns false when the config does not exist.
dsnClassMapsource public static
dsnClassMap( array $map null )
Returns or updates the DSN class map for this class
Parameters
- array
$map
optional null - Additions/edits to the class map to apply
Returns
array
array
parseDsnsource public static
parseDsn( string $dsn )
Parses a DSN into a valid connection configuration
This method allows setting a DSN using formatting similar to that used by PEAR::DB. The following is an example of its usage:
$dsn = 'mysql://user:pass@localhost/database?'; $config = ConnectionManager::parseDsn($dsn); $dsn = 'Cake\Log\Engine\FileLog://?types=notice,info,debug&file=debug&path=LOGS'; $config = Log::parseDsn($dsn); $dsn = 'smtp://user:secret@localhost:25?timeout=30&client=null&tls=null'; $config = Email::parseDsn($dsn); $dsn = 'file:///?className=\My\Cache\Engine\FileEngine'; $config = Cache::parseDsn($dsn); $dsn = 'File://?prefix=myapp_cake_core_&serialize=true&duration=+2 minutes&path=/tmp/persistent/'; $config = Cache::parseDsn($dsn);
For all classes, the value of scheme
is set as the value of both the className
unless they have been otherwise specified.
Note that querystring arguments are also parsed and set as values in the returned configuration.
Parameters
- string
$dsn
- The DSN string to convert to a configuration array
Returns
array
The configuration array to be stored after parsing the DSN
Throws
InvalidArgumentException
If not passed a string
