ConfigurableExtension
abstract class ConfigurableExtension extends Extension
This extension sub-class provides first-class integration with the Config/Definition Component.
You can use this as base class if
a) you use the Config/Definition component for configuration, b) your configuration class is named "Configuration", and c) the configuration class resides in the DependencyInjection sub-folder.
Methods

Adds annotated classes to the class cache.
Configures the passed container according to the merged configuration.
Details
string
getAlias()
Returns the recommended alias to use in XML.
This alias is also the mandatory prefix to use when using YAML.
This convention is to remove the "Extension" postfix from the class name and then lowercase and underscore the result. So:
AcmeHelloExtension
becomes
acme_hello
This can be overridden in a sub-class to specify the alias manually.
