Examples of org.apache.derby.io.StorageFile.list()

org.apache.derby.io.StorageFile.list()
Get the names of all files and sub-directories in the directory named by this path name. This method is only used in a writable database. @return An array of the names of the files and directories in thisdirectory denoted by this abstract pathname. The returned array will have length 0 if this directory is empty. Returns null if this StorageFile is not a directory, or if an I/O error occurs. The return value is undefined if the database is read-only.
