<h4 id="title">Lazy source example</h4>
<p id="shortdesc">Example of setting a layer source after construction.</p>
<div id="docs">
<p>
Typically, the source for a layer is provided to the layer constructor.
If you need to set a layer source after construction, this can be
done with the <code>layer.setSource()</code> method.
</p>
<p>
The layer in the map above is constructed with no source. Use the
links below to set/unset the layer source. A layer is not rendered
until its source is set.

<button id="set-source" class="code">layer.setSource(source)</button>
<button id="unset-source" class="code">layer.setSource(null)</button>
</p>
<p>See the <a href="lazy-source.js" target="_blank">lazy-source.js source</a> for details on how this is done.</p>
