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.
ConfigurationInterface|null
getConfiguration(array $config, ContainerBuilder $container)
Returns extension configuration.
