Method Detail

sort

protected static void sort(List<ExtensionFileFilter> filters)

updateAllFormatsImporter

public static void updateAllFormatsImporter()

Updates the AllFormatsImporter that is contained in the importers list. If you do not use the importers variable directly, you don’t need to call this.

Updating the AllFormatsImporter is required when plugins add new importers that support new file extensions. The old AllFormatsImporter doesn’t include the new extensions and thus will not display these files.

getExportExtensionFileFilters

public static List<ExtensionFileFilter> getExportExtensionFileFilters()

Replies an ordered list of enabled ExtensionFileFilters for exporting. The list is ordered according to their description, an AllFormatsImporter is append at the end.

Returns:

an ordered list of enabled ExtensionFileFilters for exporting.
