FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package event-dispatcher-util
PSR-14 Event Dispatcher Utility Library
This package contains a series of traits and base classes to cover the common, boilerplate portions of implementing a PSR-14-compliant event dispatcher library.
Install
Via Composer
Usage
Aggregate provider
The AggregateProvider class is a ListenerProvider implementation that collects and concatenates other listener providers. It is a simple wrapper that yields from a series of configured providers, in order.
The aggregate provider will now return all the listeners from YourProvider, followed by all the listeners from SomeOtherProvider.
Delegating provider
The DelegatingProvider is another multi-provider front-end. In this case, it can be configured such that certain event types will use one sub-provider, and others will use a different one. A given type can be configured with multiple sub-providers, and events will be matched using instanceof so that sub-classes of an event are also affected.
Now, events sent to the dispatcher that implement HttpEvent will be passed along to KernelListenerProvider only, while those that implement OrmEvent will be passed along to OrmListenerProvider only. Any other events will be passed on to the default provider only.
AggregateProvider and DelegateProvider are fully compatible with each other, so either can use an instance of the other as one of its sub-providers.
Parameter provider helpers
The ParameterDeriverTrait is a set of tools to help listener provider implementations with deriving the type of a callable's parameter, to know what type of event it is. PHP supports a wide variety of callable types, which are not always easy to disambiguate. The tools in this class help ease that process.
If you are not writing your own Provider registration mechanism, this trait will not be useful.
