Type ActionDependencies

object --+

        ActionDependencies


Class representing dependencies associated with an extended action.

Execution ordering for extended actions is done in one of two ways: either by using index values (lower index gets run first) or by having the extended action specify dependencies in terms of other named actions. This class encapsulates the dependency information for an extended action.

As with all of the other classes that represent configuration sections, all of these values are optional. It is up to some higher-level construct to decide whether everything they need is filled in. Some validation is done on non-None assignments through the use of the Python property() construct.

The following restrictions exist on data in this class:
Method Summary
  __init__(self, beforeList, afterList)
Constructor for the ActionDependencies class.
  __repr__(self)
Official string representation for class instance.
  __str__(self)
Informal string representation for class instance.
  __cmp__(self, other)
Definition of equals operator for this class.
    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__(...)

Method Details

__init__(self, beforeList=None, afterList=None)
(Constructor)

Constructor for the ActionDependencies class.
Parameters:
beforeList - List of named actions that this action must be run before
afterList - List of named actions that this action must be run after
Raises:
ValueError - If one of the values is invalid.
Overrides:
__builtin__.object.__init__

__repr__(self)
(Representation operator)

Official string representation for class instance.
Overrides:
__builtin__.object.__repr__

__str__(self)
(Informal representation operator)

Informal string representation for class instance.
Overrides:
__builtin__.object.__str__

__cmp__(self, other)
(Comparison operator)

Definition of equals operator for this class.
Parameters:
other - Other object to compare to.
Returns:
-1/0/1 depending on whether self is <, = or > other.

Property Details

afterList
