Extension::getAlias()

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.

Return Value

string

The alias

Exceptions

BadMethodCallException

When the extension name does not follow conventions
