Methods


					
	public

getXsdValidationBasePath(): string|false

Returns the base path for the XSD files.


					
	public

getNamespace(): string

Returns the namespace to be used for this extension (XML namespace).


					
	public

getAlias(): string

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.
