# The Fragment component
The library provides a `Fragment` class to ease fragment creation and manipulation.
## Creating a new object
~~~php
<?php
public Fragment::__construct(?string $content = null): void
~~~
<p class="message-notice">submitted string is normalized to be <code>RFC3986</code> compliant.</p>
<p class="message-warning">If the submitted value is not valid a <code>League\Uri\Components\Exception</code> exception is thrown.</p>
The `League\Uri\Components\Exception` extends PHP's SPL `InvalidArgumentException`.
## Properties and methods
This URI component object only exposes the [package common API](/components/1.0/api/).
## Usage
~~~php
<?php
use League\Uri\Components\Fragment;
$fragment = new Fragment('%E2%82%AC');
$fragment->isNull(); //returns false
$fragment->isEmpty(); //return false
echo $fragment->getContent(Fragment::RFC3986_ENCODING); //display '%E2%82%AC'
echo $fragment->getContent(Fragment::RFC3987_ENCODING); //display '€'
echo $fragment->getContent(Fragment::NO_ENCODING); //display '€'
echo $fragment; //display '%E2%82%AC'
echo $fragment->getUriComponent(); //display '#%E2%82%AC'
$new_fragment = $fragment->getContent(null);
$new_fragment->isNull(); //returns true
$new_fragment->isEmpty(); //return true
echo $new_fragment->getContent(); //display null
echo $new_fragment; //display ''
echo $new_fragment->getUriComponent(); //display ''
$alt_fragment = $fragment->getContent('');
$alt_fragment->isNull(); //returns false
$alt_fragment->isEmpty(); //return true
echo $alt_fragment->getContent(); //display ''
echo $alt_fragment; //display ''
echo $alt_fragment->getUriComponent(); //display '#'
~~~
<p class="message-notice">The delimiter <code>#</code> is not part of the component value and <strong>must not</strong> be added.</p>
<p class="message-warning">If the submitted value is not valid a <code>League\Uri\Components\Exception</code> exception is thrown.</p>
