class Default(object) |
| |
Abstract holder for a default-value or function
This is the base class for property default
classes. It is primarily an interface definition.
|
| |
Methods defined here:
- __call__(self, property, client)
- Return appropriate default value
This just returns the results of:
get( property, client )
- __init__(self, value)
- Initialize the Default holder
value -- the base value stored in the
object, see sub-classes for semantics
of how the object is treated.
- get(self, property, client)
- Get the value
Data and other attributes defined here:
- __dict__ = <dictproxy object at 0x01FE0C70>
- dictionary for instance variables (if defined)
- __weakref__ = <attribute '__weakref__' of 'Default' objects>
- list of weak references to the object (if defined)

class DefaultCallable(Default) |
| |
A holder for a callable object producing default values
The callable object is called with the signature:
callable( property, client )
where client is the instance object and property
is the BasicProperty itself.

- Method resolution order:
- DefaultCallable
- Default
- object
Methods defined here:
- __init__(self, value)
- Initialize the Default holder
value -- the base value stored in the
object, see sub-classes for semantics
of how the object is treated.
- get(self, property, client)
- Return the result of our callable value
Methods inherited from Default:
- __call__(self, property, client)
- Return appropriate default value
This just returns the results of:
get( property, client )
Data and other attributes inherited from Default:
- __dict__ = <dictproxy object at 0x01FE0CB0>
- dictionary for instance variables (if defined)
- __weakref__ = <attribute '__weakref__' of 'Default' objects>
- list of weak references to the object (if defined)

class DefaultValue(Default) |
| |
A holder for a default value
The default value is returned without modification,
so using mutable objects will retrieve the same
instance for all calls to get()
