Methods

Inherited from SettingsContainerAbstract

method	return	info
`__construct(iterable $properties = null)`	-	calls `construct()` internally after the properties have been set
(protected) `construct()`	`void`	calls a method with trait name as replacement constructor for each used trait (similar to PHP4 constructors)
`__get(string $property)`	`mixed`	calls `$this->{'get_'.$property}()` if such a method exists
`__set(string $property, $value)`	`void`	calls `$this->{'set_'.$property}($value)` if such a method exists
`__isset(string $property)`	`bool`
`__unset(string $property)`	`void`
`__toString()`	`string`	a JSON string
`toArray()`	`array`
`fromIterable(iterable $properties)`	`SettingsContainerInterface`
`toJSON(int $jsonOptions = null)`	`string`	accepts JSON options constants
`fromJSON(string $json)`	`SettingsContainerInterface`
`jsonSerialize()`	`mixed`	implements the `JsonSerializable` interface
