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 cacheable
Cacheable
Convert Closures and objects to strings in order to provide callable caching
Release notes
v1.0.0 :
- Breaking change : CacheableCall now extends CallableType from ascetik/callapsule package. Methods have been updated to match with required behavior.
- CacheableCall decorates a CallableType.
Purpose
Each time a client switches the page or submits some data, the server has to build whole system, with services, routes, middlewares... I wondered if it was possible to store some instances or functions in cache for faster system build. The main problem was the serialization of a Closure, which may be used by a router or a service container.
A short time was necessary to find the opis/closure package. This was the base to find out how to resolve my problem. This package may be still incomplete. I have to test it in a production context to get some feedback with some logs. Self-made logger package is still not done.
Vocabulary
Cacheable is the main interface. It just extends Serializable interface and nothing else for now. CacheableCall abstracts the idea of a wrapper able to serialize any callable. CacheableInstance extends an instance to be fully serializable. CacheableProperty holds the name and the value of each CacheableInstance wrapped instance.
Descriptions & Exposed Methods
Notice : The use of serialize and unserialize methods is not recommended and will certainly lead to serialization inconsistencies. Use native serialize/unserialize functions instead.
CacheableFactory (not Cacheable itself)
- wrapCall(callable): CacheableCall : Returns a CacheableCall instance
- wrapInstance(object): CacheableInstance : Returns a CacheableInstance instance
- wrapProperty(string, mixed): CacheableProperty : Returns a CacheableProperty
CacheableCall
- action(): callable : Returns registered callable as is
- apply(iterable): mixed : Calls registered callable
CacheableCall is invokable to keep it simple to use on runtime
CacheableInstance
- getClass(): string : Returns registered class name
- getProperties(): Ds\Set : Returns a container of CacheableProperties built from registered instance properties
- getInstance(): object : Returns registered instance
CacheableProperty
- getName(): string : Returns property name
- getValue(): mixed : Returns property value
Usage
Callable Wrap
The CacheableFactory provides methods to build Cacheable instances for callable types. There are three sorts of wrapper to serialize a callable :
As they all are Cacheable, so Serializable, serialization is easy :
And unserialization is easy too :
Instances Wrap
When using wrapper magic methods, Exceptions are thrown if :
- called method does not exist
- property does not exist
- property is public
Finalities
This package provides serialization and unserialization. The usage of the output is up to you.
