Details
public string getXsdValidationBasePath()
Returns the base path for the XSD files.
public string getNamespace()
Returns the namespace to be used for this extension (XML namespace).
public 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.
public ConfigurationInterface|null getConfiguration(array $config, ContainerBuilder $container)
Returns extension configuration.
