Method Details

[hide private]

_first(self)

source code

Abstract method that defines first for the subclass.

The return value should be an iterable of tuples of integers denoting paths from this node through the term tree to a symbol.

Overrides: Node._first: (inherited documentation)

_last(self)

source code

Abstract method that defines last for the subclass.

The return value should be an iterable of tuples of integers denoting paths from this node through the term tree to a symbol.

Overrides: Node._last: (inherited documentation)

_nullable(self)

source code

Abstract method that defines nullable for the subclass.

The return value should be True or False.

Overrides: Node._nullable: (inherited documentation)

_follow(self)

source code

Abstract method that defines follow for the subclass.

The return value should be a map from tuples of integers (positions) to a list of transitions, where a transition is a position and an update instruction.

Overrides: Node._follow: (inherited documentation)

_walkTermTree(self, position, pre, post, arg)

source code

Abstract method implementing walkTermTree for the subclass.

Overrides: Node._walkTermTree: (inherited documentation)
