Method Summary
	`__init__(self, original, overlay)`
	`add(self, name, entry)` Overloaded VFSDirectory method.
	`expand(self)` Creates child objects based on what original and overlay contain.
Inherited from VFSDirectory
	`entries(self)` Return list of all the entries of a directory, as [(name, entry)].
	`entryname(self, entry)` Return the name under which the given entry has been added.
	`find(self, path)` Starting at this object, find a descendant at path.
	`get(self, name)` Get a directory entry by name.
	`set_filesystem(self, filesystem)` Set my and my children's filesystem.
Inherited from OverlayEntry
	`abspath(self)` (VFSEntry implementation)...
	`original(self)`
	`overlay(self)`
	`relpath(self, from_dir)` (VFSEntry implementation)...
Inherited from VFSEntry
	`del_property(self, name)`
	`filesystem(self)`
	`get_property(self, name)`
	`is_persistent(self)` Does this entry correspond to a physical OS file system entry that can be accessed directly? This information is quite useful under certain circumstances; for example when it is better to pass the file to python's execfile(), rather than exec'ing it from memory (execfile() gives better error messages).
	`name(self)`
	`parent(self)`
	`set_parent(self, parent)`
	`set_property(self, name, value)`
	`sync(self)` Write back to the backing storage, whatever this means.
Inherited from object
	`__delattr__(...)` x.__delattr__('name') <==> del x.name...
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name...
	`__hash__(x)` x.__hash__() <==> hash(x)...
	`__new__(T, S, ...)` T.__new__(S, ...) -> a new object with type S, a subtype of T...
	`__reduce__(...)` helper for pickle...
	`__reduce_ex__(...)` helper for pickle...
	`__repr__(x)` x.__repr__() <==> repr(x)...
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value...
	`__str__(x)` x.__str__() <==> str(x)...

Class Variable Summary

Method Details

add(self, name, entry)

Overloaded VFSDirectory method. Add the appropriate VFSEntry
to VFSDirectory, and the argument entry to the original.

Returns the compound entry, not the original.

Overrides:: libconfix.core.filesys.vfs_directory.VFSDirectory.add

expand(self)

Creates child objects based on what original and overlay
contain. Does this recursively until both trees are overlay'd.

Overrides:: libconfix.core.filesys.overlay_entry.OverlayEntry.expand
