## Class ContentType

- java.lang.Object
- - org.apache.tapestry5.ContentType

-     public final class ContentType
      extends Object

  Represents an HTTP content type. Allows to set various elements like the MIME type, the character set, and other parameters. This is similar to a number of other implementations of the same concept in JAF, etc. We have created this simple implementation to avoid including the whole libraries. As of Tapestry 5.4, this is now an immutable data type.
