source code

__setitem__(self, variable, binding)
A binding is consistent with the dict if its variable is not already bound, OR if its variable is already bound to its argument.

source code

__getitem__(self, variable)
Return the expression to which 'variable' is bound

source code

__contains__(self, item)

Returns: BindingDict A new dict containing all the elements of both parameters source code

Method Details

[hide private]

init(self, binding_list=None)
(Constructor)

source code

Parameters:

binding_list - list of (AbstractVariableExpression, AtomicExpression) to initialize the dictionary

Overrides: object.__init__

setitem(self, variable, binding)
(Index assignment operator)

source code

A binding is consistent with the dict if its variable is not already bound, OR if its variable is already bound to its argument.

Parameters:

variable - Variable The variable to bind
binding - Expression The atomic to which 'variable' should be bound

Raises:

BindingException - If the variable cannot be bound in this dictionary

add(self, other)
(Addition operator)

source code

Parameters:

other - BindingDict The dict with which to combine self

Returns:

BindingDict A new dict containing all the elements of both parameters

Raises:

BindingException - If the parameter dictionaries are not consistent with each other

str(self)
(Informal representation operator)

source code

Overrides: object.__str__: (inherited documentation)

repr(self)
(Representation operator)

source code

Overrides: object.__repr__: (inherited documentation)
