IPublishedContent IsHelpers

The IsHelper methods are a set of extension methods for IPublishedContent to help perform quick conditional queries against IPublishedContent nodes in a collection.

IsHelper methods are ternary operators, however they work a little nicer since they can be embedded in properties. They are also quicker to write because fewer brackets are needed for Razor to understand them.

How to use

An IsHelper can be invoked as a method of an IPublishedContent.

@{
if(item.IsVisible())
{
<a href="@item.Url()">@item.Name</a>
}
}
