  com.saxonica.fsa.CountingState

All Implemented Interfaces:

State

public class CountingState
extends java.lang.Object
implements State

A counting state is a dynamic object representing the combination of an AutomatonState and a counter value

getTransition

public Edge getTransition(int token,
                          NamePool pool)

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

pool - the Name Pool

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 java.lang.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 java.util.Iterator 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(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
