public class MimeType extends java.lang.Object implements java.lang.Comparable<MimeType>, java.io.Serializable
This class, however, does not contain support for the q-parameters used
in HTTP content negotiation. Those can be found in the sub-class
org.springframework.http.MediaType
in the spring-web
module.
Consists of a type and a subtype.
Also has functionality to parse media types from a string using
valueOf(String)
. For more parsing options see MimeTypeUtils
.
