public MediaTypeUtils()

- Method Detail
  - parseMediaType
```
public static MediaType parseMediaType(java.lang.String mediaType)
```
    Parse the given String into a single MediaType. Recently parsed MediaType are cached for further retrieval.
    
    Parameters:
    
    mediaType - the string to parse
    
    Returns:
    
    the media type
    
    Throws:
    
    InvalidMediaTypeException - if the string cannot be parsed
  - parseMediaTypes
```
public static java.util.List<MediaType> parseMediaTypes(java.lang.String mediaTypes)
```
    Parse the comma-separated string into a list of MediaType objects.
    
    Parameters:
    
    mediaTypes - the string to parse
    
    Returns:
    
    the list of media types
    
    Throws:
    
    InvalidMediaTypeException - if the string cannot be parsed
  - tokenize
```
public static java.util.List<java.lang.String> tokenize(java.lang.String mediaTypes)
```
    Tokenize the given comma-separated string of MediaType objects into a List<String>. Unlike simple tokenization by ",", this method takes into account quoted parameters.
    
    Parameters:
    
    mediaTypes - the string to tokenize
    
    Returns:
    
    the list of tokens
  - toString
```
public static java.lang.String toString(java.util.Collection<MediaType> mediaTypes)
```
    Return a string representation of the given list of MediaType objects.
    
    Parameters:
    
    mediaTypes - the string to parse
    
    Returns:
    
    the list of media types
    
    Throws:
    
    java.lang.IllegalArgumentException - if the String cannot be parsed
  - sortBySpecificity
```
public static void sortBySpecificity(java.util.List<MediaType> mediaTypes)
```
    Sorts the given list of MediaType objects by specificity.
    Given two media types:
    
    if either media type has a wildcard type, then the media type without the wildcard is ordered before the other.
    
    if the two media types have different types, then they are considered equal and remain their current order.
    
    if either media type has a wildcard subtype , then the media type without the wildcard is sorted before the other.
    
    if the two media types have different subtypes, then they are considered equal and remain their current order.
    
    if the two media types have a different amount of parameters, then the media type with the most parameters is ordered before the other.
    
    For example:
    
    audio/basic < audio/* < */*
    
    audio/basic;level=1 < audio/basic
    
    audio/basic == text/html
    
    audio/basic == audio/wave
    Parameters:
    
    mediaTypes - the list of media types to be sorted
