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();
```
