Abstract Model used for representing user-generated geometry features. 
Inherits from Feature and adds geometry-related methods/properties
common to all geometry types.

    ``manipulators``        List of manipulators to be applied when geom

Nested Classes

[hide private]

save(self, *args, **kwargs)

source code

Overrides: Feature.save

geom_kml(self)

source code

Basic KML representation of the feature geometry

Decorators:

@property

kml(self)

source code

Fully-styled KML placemark representation of the feature. The Feature's kml property MUST

return a string containing a valid KML placemark element
the placemark must have id= [the feature's uid]
if it references any style URLs, the corresponding Style element(s) must be provided by the feature's .kml_style property

Decorators:

@property

kml_style(self)

source code

Must return a string with one or more KML Style elements whose id's may be referenced by relative URL from within the feature's .kml string In any given KML document, each *unique* kml_style string will get included so don't worry if you have 10 million features with "blah-default" style... only one will appear in the final document and all the placemarks can refer to it. BEST TO TREAT THIS LIKE A CLASS METHOD - no instance specific vars.

Decorators:

@property

active_manipulators(self)

source code


This method contains all the logic to determine which manipulators get applied to a feature

If self.manipulators doesnt exist or is null or blank, 
   apply the required manipulators (or the NullManipulator if none are required)

If there is a self.manipulators string and there are optional manipulators contained in it,
   apply the required manipulators PLUS the specified optional manipulators

Decorators:

@property
