getTransition

public Edge getTransition(int token,
                          Configuration config)

Description copied from interface: State

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

Specified by:

getTransition in interface State

Parameters:

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

config - the Saxon configuration

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

public boolean isFinalState()

Specified by:

isFinalState in interface State

getUnderlyingState

public AutomatonState getUnderlyingState()

listAllowedElements

public CharSequence listAllowedElements()

Specified by:

listAllowedElements in interface State

getWildcardEdges

public Edge[] getWildcardEdges()

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

Specified by:

getWildcardEdges in interface State

Returns:

an Iterator over the edges that represent element wildcards. The objects returned by this Iterator are Edge objects.

getEdges

public Iterator<Edge> getEdges()

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

Specified by:

getEdges in interface State

Returns:

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

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
