ReflectionDocBlock
|
|
==================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser
|
|
that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest).
|
|
|
|
With this component, a library can provide support for annotations via DocBlocks
|
|
or otherwise retrieve information that is embedded in a DocBlock.
|
|
|
|
Installation
|
|
------------
|
|
|
|
```bash
|
|
composer require phpdocumentor/reflection-docblock
|
|
```
|
|
|
|
Usage
|
|
-----
|
|
|
|
In order to parse the DocBlock one needs a DocBlockFactory that can be
|
|
instantiated using its `createInstance` factory method like this:
|
|
|
|
```php
|
|
$factory = \phpDocumentor\Reflection\DocBlockFactory::createInstance();
|
|
```
|
|
|
|
Then we can use the `create` method of the factory to interpret the DocBlock.
|
|
Please note that it is also possible to provide a class that has the
|
|
`getDocComment()` method, such as an object of type `ReflectionClass`, the
|
|
create method will read that if it exists.
|
|
|
|
```php
|
|
$docComment = <<<DOCCOMMENT
|
|
/**
|
|
* This is an example of a summary.
|
|
*
|
|
* This is a Description. A Summary and Description are separated by either
|
|
* two subsequent newlines (thus a whiteline in between as can be seen in this
|
|
* example), or when the Summary ends with a dot (`.`) and some form of
|
|
* whitespace.
|
|
*/
|
|
DOCCOMMENT;
|
|
|
|
$docblock = $factory->create($docComment);
|
|
```
|
|
|
|
The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock`
|
|
whose methods can be queried:
|
|
|
|
```php
|
|
// Contains the summary for this DocBlock
|
|
$summary = $docblock->getSummary();
|
|
|
|
// Contains \phpDocumentor\Reflection\DocBlock\Description object
|
|
$description = $docblock->getDescription();
|
|
|
|
// You can either cast it to string
|
|
$description = (string) $docblock->getDescription();
|
|
|
|
// Or use the render method to get a string representation of the Description.
|
|
$description = $docblock->getDescription()->render();
|
|
```
|
