Package teamwork :: Package action :: Module DecisionSpace :: Class DecisionSpace

Class DecisionSpace

Known Subclasses:

Space of possible options that an agent may have Each option is assumed to be a dictionary-type object. A DecisionSpace object generates all of the possible objects that can be generated by extending a given base (partially filled) object with a given key, whose value ranges over a supplied list of possible fillers.

Instance Methods

source code

append(self, value)
Adds the given value to the list of possible fillers

source code

remove(self, value)

Method Details

[hide private]

init(self, key=None, values=`[]`, base=None)
(Constructor)

source code

Constructor that initializes the base option and relevant key

Parameters:

key (string) - the dictionary key over which this decision space generates possible fillers
base - the original dictionary object that is to be filled in (by default, a list containing a single empty Action object)

directAdd(self, option)

source code

Adds the given option directly to the space

Parameters:

option (Action[]) - the option to add to the space

append(self, value)

source code

Adds the given value to the list of possible fillers

Parameters:

value (str)

remove(self, value)

source code

Removes the given value from the list of possible fillers

Returns:: false if the value is not present; otherwise, true

replace(self, old, new)

source code

Replaces single old value with new values

Parameters:

old - a single value
new - a list of values
The method continues the replacement by descending recursively if there are any nested decision spaces

getOptions(self)

source code

Accessor for the options in this space

Returns:: a list of possible options (typically, Action instances)
