class CCGVar(AbstractCCGCategory): (source)

Constructor: CCGVar(prim_only)

View In Hierarchy

Class representing a variable CCG category. Used for conjunctions (and possibly type-raising, if implemented as a unary rule).

Class Method new_id A class method allowing generation of unique variable identifiers.
Class Method reset_id Undocumented
Method __init__ Initialize a variable (selects a new identifier)
Method __str__ Undocumented
Method can_unify If the variable can be replaced with other a substitution is returned.
Method id Undocumented
Method is_function Returns true if the category is a function application.
Method is_primitive Returns true if the category is primitive.
Method is_var Returns true if the category is a variable.
Method substitute If there is a substitution corresponding to this variable, return the substituted category.

Undocumented

def is_function(self): (source)
overrides nltk.ccg.api.AbstractCCGCategory.is_function

Returns true if the category is a function application.

def is_primitive(self): (source)
overrides nltk.ccg.api.AbstractCCGCategory.is_primitive

Returns true if the category is primitive.

def is_var(self): (source)
overrides nltk.ccg.api.AbstractCCGCategory.is_var

Returns true if the category is a variable.

def substitute(self, substitutions): (source)
overrides nltk.ccg.api.AbstractCCGCategory.substitute

If there is a substitution corresponding to this variable, return the substituted category.
