Detailed Description

Class which contains the Nodes for the 'By Mime Type' view located in the File Types view, shows all files with a mime type. Will initially be empty until file type identification has been performed. Contains a Property Change Listener which is checking for changes in IngestJobEvent Completed or Cancelled and IngestModuleEvent Content Changed.

static boolean org.sleuthkit.autopsy.datamodel.FileTypesByMimeType.isEmptyMimeTypeNode ( Node  node )

static

Method to check if the node in question is a ByMimeTypeNode which is empty.

Parameters

node	the Node which you wish to check.

Returns

True if originNode is an instance of ByMimeTypeNode and is empty, false otherwise.

Member Data Documentation

final HashMap<String, List<String> > org.sleuthkit.autopsy.datamodel.FileTypesByMimeType.existingMimeTypes = new HashMap<>()

private

The nodes of this tree will be determined dynamically by the mimetypes which exist in the database. This hashmap will store them with the media type as the key and a list of media subtypes as the value.
