|
|
| Parsing functions
|
|
|
| :: Monad m | | | => [String] | The result, a tuple of group
UUID and group object
| | -> m (String, Group) | | | Load a group from a field list.
|
|
|
|
| :: Monad m | | | => NameAssoc | Input data as a list of fields
| | -> [String] | The result, a tuple o node name
and node object
| | -> m (String, Node) | | | Load a node from a field list.
|
|
|
|
| :: NameAssoc | Association list with the current nodes
| | -> [String] | Input data as a list of fields
| | -> Result (String, Instance) | A tuple of
instance name and
the instance object
| | Load an instance from a field list.
|
|
|
|
| Loads a spec from a field list.
|
|
|
| Loads an ipolicy from a field list.
|
|
|
|
|
| Loads all policies from the policy section
|
|
|
| :: (Monad m, Element a) | | | => [String] | Conversion function
| | -> [String] -> m (String, a) | A tuple of an
association list (name
to object) and a set as
used in
Ganeti.HTools.Container
| | -> m (NameAssoc, Container a) | | Convert newline and delimiter-separated text.
This function converts a text in tabular format as generated by
gnt-instance list and gnt-node list to a list of objects using
a supplied conversion function.
|
|
|
|
| :: String | Path to the text file
| | -> IO String | Contents of the file
| Load the cluser data from disk.
This is an alias to readFile just for consistency with the other
modules.
|
|
|
|
|
|
|
| :: String | Path to the text file
| | -> IO (Result ClusterData) | | | Top level function for data loading.
