Method	__str__	Undocumented
Method	free	Set of free variables.
Method	replace	Replace all instances of variable v with expression E in self, where v is free in self.
Method	_pretty	Undocumented

Inherited from DrtExpression:

Class Method	fromstring	Undocumented
Method	__add__	Undocumented
Method	__and__	Undocumented
Method	__gt__	Undocumented
Method	__neg__	Undocumented
Method	__or__	Undocumented
Method	applyto	Undocumented
Method	draw	Undocumented
Method	eliminate_equality	Undocumented
Method	equiv	Check for logical equivalence. Pass the expression (self <-> other) to the theorem prover. If the prover says it is valid, then the self and other are equal.
Method	get_refs	Return the set of discourse referents in this DRS. :param recursive: bool Also find discourse referents in subterms? :return: list of Variable objects
Method	is_pronoun_function	Is self of the form "PRO(x)"?
Method	make_EqualityExpression	Undocumented
Method	make_VariableExpression	Undocumented
Method	pretty_format	Draw the DRS :return: the pretty print string

Method	__eq__	Undocumented
Method	__hash__	Undocumented
Method	__lt__	Undocumented
Method	__ne__	Undocumented
Method	__repr__	Undocumented
Method	constants	Return a set of individual constants (non-predicates). :return: set of Variable objects
Method	findtype	Find the type of the given variable as it is used in this expression. For example, finding the type of "P" in "P(x) & Q(x,y)" yields "<e,t>"
Method	negate	If this is a negated expression, remove the negation. Otherwise add a negation.
Method	normalize	Rename auto-generated unique variables
Method	predicates	Return a set of predicates (constants, not variables). :return: set of Variable objects
Method	simplify	No summary
Method	substitute_bindings	No summary
Method	variables	Return a set of all the variables for binding substitution. The variables returned include all free (non-bound) individual variables and any variable starting with '?' or '@'. :return: set of Variable objects...
Method	visit	Recursively visit subexpressions. Apply 'function' to each subexpression and pass the result of each function application to the 'combinator' for aggregation:
Method	visit_structured	Recursively visit subexpressions. Apply 'function' to each subexpression and pass the result of each function application to the 'combinator' for aggregation. The combinator must have the same signature as the constructor...
Method	_set_type	Set the type of this expression to be the given type. Raise type exceptions where applicable.
