Class BindingDict

object --+ | BindingDict

Instance Methods

__init__(self, binding_list=None)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

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)

source code

__add__(self, other)
Returns: BindingDict A new dict containing all the elements of both parameters source code

__len__(self)

source code

__str__(self)
str(x)

source code

__repr__(self)
repr(x)

init(self, binding_list=None)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

binding_list - list of (VariableExpression, 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

str(x)

Overrides: object.__str__: (inherited documentation)

repr(self)
(Representation operator)

source code

repr(x)

Overrides: object.__repr__: (inherited documentation)
