```
public class ContentTypeUtil
extends Object
```
A utility for selecting content types, in the context of the Accept header. ------------------- This does not support matching against content types with extensions, like "level=1", as illustrated in RFC-2616: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1 However, as long as we don't offer such extensions on our available types, the use of extensions in the Accept header is moot.

public static String bestContentType(String acceptHeader,
                                     Collection<String> availableTypeNames)
                              throws AcceptHeaderParsingException,
                                     NotAcceptableException
```
    Given an Accept header value and a list of available type names, decide which type is the best fit. If there is no fit, throw a NotAcceptableException The only thing to do is to match all available against all acceptable, and pick the best match. Try to do as little work as possible inside the nested loop.
    
    Throws:
    
    AcceptHeaderParsingException
    
    NotAcceptableException

```
    The order of items in the Accept header is not important. We rely on the specificity of the match and the "q" factor, in that order. Since q ranges between 1.0 and 0.001, we add a specificity offset of 2, 3 or 4. That way, matches with equal specificity are decided by q factor.
    
    Throws:
    
    AcceptHeaderParsingException
