Class MimeType

java.lang.Object
  de.grogra.util.MimeType

All Implemented Interfaces:

java.io.Serializable

public final class MimeType
extends java.lang.Object
implements java.io.Serializable

This class implements a MIME type as specified by RFC 2045 and 2046. A MIME type consists of the specification of a top-level media type and a subtype, e.g., text/plain, and a (possibly empty) set of parameters. In the string representation of a MIME type, parameters are specified as the parameter charset in text/plain; charset=iso-8859-1.
