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.
Property Summary
-
$_config protected static
arrayConfiguration sets.
Method Summary
-
configured() public static
Returns an array containing the named configurations
-
drop() public static
Drops a constructed adapter.
-
getConfig() public static
Reads existing configuration.
-
getConfigOrFail() public static
Reads existing configuration for a specific key.
-
getDsnClassMap() public static
Returns the DSN class map for this class.
-
parseDsn() public static
Parses a DSN into a valid connection configuration
-
setConfig() public static
This method can be used to define configuration adapters for an application.
-
setDsnClassMap() public static
Updates the DSN class map for this class.
Method Detail
configured() ¶ public static
configured(): string[]Returns an array containing the named configurations
Returns
string[]drop() ¶ public static
drop(string $config): boolDrops 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
boolgetConfig() ¶ public static
getConfig(string $key): mixed|nullReads existing configuration.
Parameters
-
string$key The name of the configuration.
Returns
mixed|nullgetConfigOrFail() ¶ public static
getConfigOrFail(string $key): mixedReads existing configuration for a specific key.
The config value for this key must exist, it can never be null.
Parameters
-
string$key The name of the configuration.
Returns
mixedThrows
InvalidArgumentExceptionIf value does not exist.
getDsnClassMap() ¶ public static
getDsnClassMap(): string[]Returns the DSN class map for this class.
Returns
string[]parseDsn() ¶ public static
parseDsn(string $dsn): arrayParses 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
arrayThrows
InvalidArgumentExceptionIf not passed a string, or passed an invalid string
setConfig() ¶ public static
setConfig(string|array $key, array|object|null $config = null): voidThis method can be used to define configuration adapters for an application.
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:
Setting a cache engine up.
Cache::setConfig('default', $settings);Injecting a constructed adapter in:
Cache::setConfig('default', $instance);Configure multiple adapters at once:
Cache::setConfig($arrayOfConfig);Parameters
-
string|array$key The name of the configuration, or an array of multiple configs.
-
array|object|null$config optional An array of name => configuration data for adapter.
Returns
voidThrows
BadMethodCallExceptionWhen trying to modify an existing config.
LogicExceptionWhen trying to store an invalid structured config array.
setDsnClassMap() ¶ public static
setDsnClassMap(string[] $map): voidUpdates the DSN class map for this class.
Parameters
-
string[]$map Additions/edits to the class map to apply.
Returns
void
