Class File

java.lang.Object

file.File

public class File
extends java.lang.Object

Class File and its related classes derive from Section 2.7 of the requirements, which in turn derives from the commands on the 'File' menu.

A File is an abstraction of a file stored in the file space. It has a name, permissions, type, and data. These are the components sufficient to specify the behavior of Calendar Tool file operations.

Field Detail

name

java.lang.String name

The string representation of a file name is an abstraction of file names used in specific operating environments. Implementations may obey any syntactic or semantic constraints imposed by a particular environment.

permissions

FilePermissions permissions

FilePermissions indicate whether a file is readable and/or writable.

type

FileType type

File type is either "calendar" or "other".

size

int size

The size in megabytes of a file. This concrete measure is used here instead of number of calendar elements since at this level we are concerned with physical file storage, not logical number of items.

data

FileData data

File data is defined abstractly as a UserCalendar. In the concrete implementation, these data will be serialized or otherwise suitably represented to be stored on a concrete file storage medium.
