Class _DFAState

object --+ | _DFAState

Base class for a suspended DFA interpretation.

Instance Methods

[hide private]

__init__(self, content_model, state=1)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

state(self)
The current state of the automaton, represented as an integer.

source code

contentModel(self)
The ContentModel to which the state belongs.

source code

updateState(self, state)
Change the automaton state recorded in this DFA state.

source code

step(self, dfa_stack, ctd_instance, value, element_use)
Execute a step within the content model.

source code

isFinal(self)
Return True iff the current state of the content model is a final state. source code

step(self, dfa_stack, ctd_instance, value, element_use)

source code

Execute a step within the content model.

This determines whether the current state in the content model allows a transition on the given value. If a transition can be performed, the instance element use corresponding to the value is used to record the value.

The input value should be an instance of basis._TypeBinding_mixin, or a value that can be uniquely converted into such a instance using the transitions from the current state as clues.

Parameters:

dfa_stack (DFAStack) - The current state of the parse. Upon return, this may have been augmented with suspended content models.
value (xml.dom.Node or basis._TypeBinding_mixin or other value) - A value upon which transition should occur.

Returns:

True iff a transition successfully consumed the value
