Class FilterMIMEType

java.lang.Object

freenet.client.filter.FilterMIMEType

public class FilterMIMEType
extends java.lang.Object

A MIME type, for purposes of the filter. There is one instance of this class for every MIME type that we have a filter for or that we have some knowledge of. Hence we can either filter the content or generate a localised warning page with specific information such as the name of the format and what the likely threats are.

See Also:

MediaType represents an individual parsed MIME type string, e.g. "text/plain; charset=ISO-8859-1".
