Class DerivationTrace

        DerivationTrace

Stores a trace of the derivation of a particular CCGCategory node and is associated with that category. For parse results, these structures will often be so large that there's no hope of being able to print the thing (even recursing to count the size can be prohibitively slow!).

Instance Methods

[hide private]

__init__(self, result, rule=None, args=[], word=None)
rule and args may be specified to give the derivation node an initial pointer to a rule that was applied and a list of the arguments for that rule. source code

add_rule(self, rule, args=[])
Add a rule application to the derivation node (that resulted in the same category as other rule applications stored here). source code

add_rules_from_trace(self, other_trace)

source code

__str__(self)

init(self, result, rule=None, args=`[]`, word=None)
(Constructor)

source code

rule and args may be specified to give the derivation node an initial pointer to a rule that was applied and a list of the arguments for that rule. Add more rules using add_rule().

All rule applications stored should have resulted in result.

Overrides: object.__init__

add_rule(self, rule, args=`[]`)

source code

Add a rule application to the derivation node (that resulted in the same category as other rule applications stored here). The rule is a pointer to the rule object that was applied. The args is a list of the arguments to which the rule was applied.
