Special operator to represent coordination. Beta reduction collapses nested coordinations into one.

Method Details [hide private]

__init__(self, cadences=[], *args, **kwargs)
(Constructor)

source code 

Builds a basic logical form object.

Overrides: object.__init__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

str(x)

Overrides: object.__str__
(inherited documentation)

__eq__(self, other)
(Equality operator)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.__eq__
(inherited documentation)

set_time(self, time)

source code 

Should be overridden by subclasses.

Sets the start time of this logical form. This is different to just setting the time property: using set_time() may pass the time property down to its children if that is appropriate for the semantic type.

It is also distinct from set_all_times(), which recursively sets the time on all children.

This must be provided by all subclasses.

Overrides: base.semantics.temporal.Temporal.set_time
(inherited documentation)

copy(self)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.copy
(inherited documentation)

alpha_convert(self, src, trg)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.alpha_convert
(inherited documentation)

beta_reduce(self, *args, **kwargs)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.beta_reduce
(inherited documentation)

substitute(self, src, trg)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.substitute
(inherited documentation)

replace_immediate_constituent(self, old_lf, new_lf)

source code 

This should be overridden by subclasses. It should replace the LogicalForm old_lf with new_lf if it appears as an immediate constituent of this LogicalForm.

Overrides: base.semantics.lambdacalc.LogicalForm.replace_immediate_constituent
(inherited documentation)

get_variables(self)

source code 

This should be overridden by subclasses.

This method returns a list of all the variables used in this LF. This includes bound and unbound variables. (Only unbound variables need to be alpha-converted to avoid accidental binding, but we will convert bound variables too for readability.)

Note that this only contains one instance of each variable, not every occurrence.

Overrides: base.semantics.lambdacalc.LogicalForm.get_variables
(inherited documentation)

get_bound_variables(self)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.get_bound_variables
(inherited documentation)

get_children(self)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.get_children
(inherited documentation)

alpha_equivalent(self, other, substitution)

source code 

This should be overridden by subclasses.

Overrides: base.semantics.lambdacalc.LogicalForm.alpha_equivalent
(inherited documentation)
