object-file

Object-Oriented Folder/Directory Class.

• Each folder are an object.
• Each folder object could have many attributes.
  • It could be all defined in the index file(README) or .value file of a folder.
  • It could be defined in the attribute files(.[AttributeName]) of a folder separately.
  • The separately attributes priority is greater than the attributes in the index file.
  • The attribute could be an object(folder) too.
• The folder(directory) tree is the inheritance tree of the object.

Mechanism

• LRU Cache
  • All file objects are cached into a global LRU Cache.
  • Some parent object could not be in memory always.
• Lazy Loading

Inheritance

• The child object inherits all attributes of the parent object by default.
• The parent object can disable some attributes to be inherited by child(not allowed to be inherited).
  • Inheritable

Object on file system

• The folder name is an object name.
• The attribute name starts with the dot('.') char.
• The extension name means the format of the contents.
