| public abstract addParameter(string $name, $value) : void Adds a parameter to the service locator that can be injected in a tag's factory method. When calling a tag's "create" method we always check the signature for dependencies to inject. One way is to typehint a parameter in the signature so that we can use that interface or class name to inject a dependency (see {@see \addService()} for more information on that). Another way is to check the name of the argument against the names in the Service Locator. With this method you can add a variable that will be inserted when a tag's create method is not typehinted and has a matching name. Be aware that there are two reserved names:
These parameters are injected at the last moment and will override any existing parameter with those names.

| public abstract addService(object $service) : void Registers a service with the Service Locator using the FQCN of the class or the alias, if provided. When calling a tag's "create" method we always check the signature for dependencies to inject. If a parameter has a typehint then the ServiceLocator is queried to see if a Service is registered for that typehint. Because interfaces are regularly used as type-hints this method provides an alias parameter; if the FQCN of the interface is passed as alias then every time that interface is requested the provided service will be returned. |
| public abstract registerTagHandler(string $tagName, $handler) : void Registers a handler for tags. If you want to use your own tags then you can use this method to instruct the TagFactory to register the name of a tag with the FQCN of a 'Tag Handler'. The Tag handler should implement the {@see \Tag} interface (and thus the create method).
