Method	__init__	Initialize.
Method	getChild	Retrieve a 'child' resource from me.

Inherited from Resource:

Class Variable	server	Undocumented
Instance Variable	children	Undocumented
Class Variable	isLeaf	Signal if this IResource implementor is a "leaf node" or not. If True, getChildWithDefault will not be called on this Resource.
Method	listStaticNames	Undocumented
Method	listStaticEntities	Undocumented
Method	listNames	Undocumented
Method	listEntities	Undocumented
Method	listDynamicNames	Undocumented
Method	listDynamicEntities	Undocumented
Method	getStaticEntity	Undocumented
Method	getDynamicEntity	Undocumented
Method	delEntity	Undocumented
Method	reallyPutEntity	Undocumented
Method	getChildWithDefault	Retrieve a static or dynamically generated child resource from me.
Method	getChildForRequest	Undocumented
Method	putChild	Register a static child.
Method	render_HEAD	Default handling of HEAD method.

Inherited from FilePath:

Instance Variable	alwaysCreate	When opening this file, only succeed if the file does not already exist.
Instance Variable	path	The path from which 'downward' traversal is permitted.
Method	__getstate__	Support serialization by discarding cached `os.stat` results and returning everything else.
Property	sep	Return a filesystem separator.
Method	asBytesMode	Return this `FilePath` in `bytes`-mode.
Method	asTextMode	Return this `FilePath` in `unicode`-mode.
Method	child	Create and return a new `FilePath` representing a path contained by `self`.
Method	preauthChild	Use me if `path` might have slashes in it, but you know they're safe.
Method	childSearchPreauth	Return my first existing child with a name in `paths`.
Method	siblingExtensionSearch	Attempt to return a path with my name, given multiple possible extensions.
Method	realpath	Returns the absolute target as a `FilePath` if self is a link, self otherwise.
Method	siblingExtension	Attempt to return a path with my name, given the extension at `ext`.
Method	linkTo	Creates a symlink to self to at the path in the `FilePath` `linkFilePath`.
Method	open	Open this file using `mode` or for writing if `alwaysCreate` is `True`.
Method	restat	Re-calculate cached effects of 'stat'. To refresh information on this path after you know the filesystem may have changed, call this method.
Method	changed	Clear any cached information about the state of this path on disk.
Method	chmod	Changes the permissions on self, if possible. Propagates errors from `os.chmod` up.
Method	getsize	Retrieve the size of this file in bytes.
Method	getModificationTime	Retrieve the time of last access from this file.
Method	getStatusChangeTime	Retrieve the time of the last status change for this file.
Method	getAccessTime	Retrieve the time that this file was last accessed.
Method	getInodeNumber	Retrieve the file serial number, also called inode number, which distinguishes this file from all other files on the same device.
Method	getDevice	Retrieves the device containing the file. The inode number and device number together uniquely identify the file, but the device number is not necessarily consistent across reboots or system crashes.
Method	getNumberOfHardLinks	Retrieves the number of hard links to the file.
Method	getUserID	Returns the user ID of the file's owner.
Method	getGroupID	Returns the group ID of the file.
Method	getPermissions	Returns the permissions of the file. Should also work on Windows, however, those permissions may not be what is expected in Windows.
Method	exists	Check if this `FilePath` exists.
Method	isdir	Check if this `FilePath` refers to a directory.
Method	isfile	Check if this file path refers to a regular file.
Method	isBlockDevice	Returns whether the underlying path is a block device.
Method	isSocket	Returns whether the underlying path is a socket.
Method	islink	Check if this `FilePath` points to a symbolic link.
Method	isabs	Check if this `FilePath` refers to an absolute path.
Method	listdir	List the base names of the direct children of this `FilePath`.
Method	splitext	Split the file path into a pair `(root, ext)` such that `root + ext == path`.
Method	__repr__	Undocumented
Method	touch	Updates the access and last modification times of the file at this file path to the current time. Also creates the file if it does not already exist.
Method	remove	Removes the file or directory that is represented by self. If `self.path` is a directory, recursively remove all its children before removing the directory. If it's a file or link, just delete it.
Method	makedirs	Create all directories not yet existing in `path` segments, using `os.makedirs`.
Method	globChildren	Assuming I am representing a directory, return a list of FilePaths representing my children that match the given pattern.
Method	basename	Retrieve the final component of the file path's path (everything after the final path separator).
Method	dirname	Retrieve all of the components of the `FilePath`'s path except the last one (everything up to the final path separator).
Method	parent	A file path for the directory containing the file at this file path.
Method	setContent	Replace the file at this path with a new file that contains the given bytes, trying to avoid data-loss in the meanwhile.
Method	__cmp__	Undocumented
Method	createDirectory	Create the directory the `FilePath` refers to.
Method	requireCreate	Sets the `alwaysCreate` variable.
Method	create	Exclusively create a file, only if this file previously did not exist.
Method	temporarySibling	Construct a path referring to a sibling of this path.
Method	copyTo	Copies self to destination.
Method	moveTo	Move self to destination - basically renaming self to whatever destination is named.
Instance Variable	_statinfo	Undocumented
Method	_asBytesPath	Return the path of this `FilePath` as bytes.
Method	_asTextPath	Return the path of this `FilePath` as text.
Method	_getPathAsSameTypeAs	If `pattern` is `bytes`, return `FilePath.path` as `bytes`. Otherwise, return `FilePath.path` as `unicode`.
Class Variable	_chunkSize	Undocumented

Inherited from AbstractFilePath (via FilePath):

Method	getContent	Retrieve the contents of the file at this path.
Method	parents	Retrieve an iterator of all the ancestors of this path.
Method	children	List the children of this path object.
Method	walk	Yield myself, then each of my children, and each of those children's children in turn.
Method	sibling	Return a `FilePath` with the same directory as this instance but with a basename of `path`.
Method	descendant	Retrieve a child or child's child of this path.
Method	segmentsFrom	Return a list of segments between a child and its ancestor.
Method	__hash__	Hash the same as another `FilePath` with the same path as mine.
Method	getmtime	Deprecated. Use getModificationTime instead.
Method	getatime	Deprecated. Use getAccessTime instead.
Method	getctime	Deprecated. Use getStatusChangeTime instead.

def __init__(self, pathname): (source)

overrides twisted.web.resource.Resource.__init__

Initialize.

def getChild(self, path, request): (source)

overrides twisted.web.resource.Resource.getChild

Retrieve a 'child' resource from me.

Implement this to create dynamic resource generation -- resources which are always available may be registered with self.putChild().

This will not be called if the class-level variable 'isLeaf' is set in your subclass; instead, the 'postpath' attribute of the request will be left as a list of the remaining path elements.

For example, the URL /foo/bar/baz will normally be:

  | site.resource.getChild('foo').getChild('bar').getChild('baz').

However, if the resource returned by 'bar' has isLeaf set to true, then the getChild call will never be made on it.

Parameters and return value have the same meaning and requirements as those defined by IResource.getChildWithDefault.

def render(self, request): (source)

from twisted.web.resource.IResource

overrides twisted.web.resource.Resource.render

Render a given resource. See IResource's render method.

I delegate to methods of self with the form 'render_METHOD' where METHOD is the HTTP that was used to make the request. Examples: render_GET, render_HEAD, render_POST, and so on. Generally you should implement those methods instead of overriding this one.

render_METHOD methods are expected to return a byte string which will be the rendered page, unless the return value is server.NOT_DONE_YET, in which case it is this class's responsibility to write the results using request.write(data) and then call request.finish().

Old code that overrides render() directly is likewise expected to return a byte string or NOT_DONE_YET.
