eu.fbk.knowledgestore.filestore.FileExistsException

All Implemented Interfaces:

Serializable

public class FileExistsException
extends IOException

Signals an attempt at creating a file that already exists.

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 external creation of a file with the same filename. Mandatory property getFilename() provides the name of the existing file.

Note: a specific exception has been introduced as the existing java.nio.file.FileAlreadyExistsException is strictly related to the JDK FileSystem class and to the access to files on OS-managed filesystems.
