eu.fbk.knowledgestore.filestore.FileMissingException

All Implemented Interfaces:

Serializable

public class FileMissingException
extends IOException

Signals an attempt at accessing a non existing file.

This exception may denote either an error of the caller (in case it previously created the specified file) or an external modification to the FileStore resulting in the removal of a file previously created, which thus becomes missing. Mandatory property getFilename() provides the name of the missing file.

Note: a specific exception has been introduced as the existing java.io.FileNotFoundException and java.nio.file.NoSuchFileException are strictly related to JDK classes and the access to files on an OS-managed filesystem.
