Interface State

All Known Implementing Classes:

AutomatonState, CountingState, DeterminizedState, NonDeterminizedState, SuffixState

public interface State

A State is a dynamic state of the finite state machine. It may either be a static (non-counting) AutomatonState, or a dynamically-created CountingState, which represents the combination of an AutomatonState and a counter value

Method Detail

getTransition

Edge getTransition(int token,
                 UserComplexType type)

Find the edge representing the transition from this state to another state, that is triggered by a given input token

Parameters:

token - the input token, specifically the fingerprint of an element name

type - the complex type whose content model we are validating against

Returns:

the Edge representing the selected transition of the finite state machine, or null if this token is not accepted when in this State (which implies a validation error).

isFinalState

boolean isFinalState()

listAllowedElements

CharSequence listAllowedElements()

getWildcardEdges

Edge[] getWildcardEdges()

Get an array of the wildcard transitions (edges) allowed from this state.

Returns:

an array containing all the edges that represent element wildcards.

getEdges

Iterator<Edge> getEdges()

Get an iterator over all the transitions (edges) allowed from this state

Returns:

an Iterator over all the edges from this state. The objects returned by this Iterator are Edge objects.
