README

This library provides the interface BjoernGoetschke\UniqueID\UidGeneratorInterface to generate unique identifiers.

Basic usage

Software that needs unique identifiers can use an object that implements the interface BjoernGoetschke\UniqueID\UidGeneratorInterface to request unique identifiers on demand by calling the generate() method.

/** @var \BjoernGoetschke\UniqueID\UidGeneratorInterface $generator */
// `$uid` will contain a random uid string that is between 10 and 50 characters long
$uid = $generator->generate(10, 50);

Installation

The library is available via Composer:

composer require bjoern-goetschke/unique-id:^4.0

Versioning

Releases will be numbered with the following format using semantic versioning:

<major>.<minor>.<patch>

And constructed with the following guidelines:

Breaking backwards compatibility bumps the major
New additions without breaking backwards compatibility bumps the minor
Bug fixes and misc changes bump the patch

For more information on semantic versioning, please visit http://semver.org/.

See API usage and backwards compatibility for detailed information about how to use the library in a way that will not break on updates and what is considered a backward incompatible change.

LICENSE

The library is released under the BSD-2-Clause license. You can find a copy of this license in LICENSE.txt.

API usage and backwards compatibility

Information about the intended usage of interfaces, classes, methods, etc. is specified with the @api tag.

If an element does not contain the @api tag it should be considered internal and usage may break at any time.

One exception to this rule are special elements like constructors, destructors or other hook methods that are defined by the programming language. These elements will not have their own @api tag but can be considered as if they have the same @api tag as the class or whatever other element they belong to.

The library DOES NOT provide a backwards-compatibility promise for parameter names. Methods will have the @no-named-arguments tag to help static analysis tools in detecting and warning about using the library with named arguments, but in case it is missing somewhere that does not mean that a backwards-compatibility promise is given for that specific method.

`@api usage`

Classes
- Create new instances of the class
  - may break on major-releases
- Extending the class and adding a new constructor
  - may break on major-releases
- Extending the class and adding new methods
  - may break at any time, but minor-releases should be ok most of the time (will break if a non-private method has been added to the base class that was also declared in the extending class)
Methods
- Calling the method
  - may break on major-releases
- Overriding the method (extending the class and declaring a method with the same name) and eventually adding additional optional arguments
  - may break at any time, but minor-releases should be ok most of the time (will break if an optional argument has been added to the method in the base-class)
Interfaces
- Using the interface in type-hints (require an instance of the interface as argument)
  - may break on major-releases
- Calling methods of the interface
  - may break on major-releases
- Implementing the interface
  - may break at any time, but minor-releases should be ok most of the time (will break if new methods have been added to the interface)
- Extending the interface
  - may break at any time, but minor-releases should be ok most of the time (will break if a method has been added to the base interface that was also declared in the extending interface)

`@api extend`

Classes
- Create new instances of the class
  - may break on major-releases
- Extending the class and adding a new constructor
  - may break on major-releases
- Extending the class and adding new methods
  - may break on minor-releases, but it should be ok most of the time and may only break on major-releases (will break if a non-private method has been added to the base class that was also declared in the extending class)
Methods
- Calling the method
  - may break on major-releases
- Overriding the method (extending the class and declaring a method with the same name) and eventually adding additional optional arguments
  - may break on major-releases
Interfaces
- Using the interface in type-hints (require an instance of the interface as argument)
  - may break on major-releases
- Calling methods of the interface
  - may break on major-releases
- Implementing the interface
  - may break on major-releases
- Extending the interface
  - may break on major-releases

`@api stable`

Everything that is marked as stable may only break on major-releases, this means that except some minor internal changes or bugfixes the code will just never change at all

`@api internal`

Everything that is marked as internal may break at any time, but patch-releases should be ok most of the time
