 AccStateTypeProduceNode<I,E,K,V> targetAcc)

Method Details

getGonType

public GonType getGonType()

Description copied from interface: AccStateGon

The GON type which this accumulator produces.

getMatchStateId

Overrides:

beginActual in class AccStateBase<I,E,K,V>

Throws:

IOException

transitionActual

public AccStateGon<I,E,K,V> transitionActual(Object inputStateId,
 I input,
 E env)
                                      throws IOException

Accepts a triple if source and field id match that of the current state

Specified by:

transitionActual in class AccStateBase<I,E,K,V>

Throws:

IOException

endActual

public void endActual()
               throws IOException

Overrides:

endActual in class AccStateBase<I,E,K,V>

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object

children

public Iterator<? extends AccStateGon<I,E,K,V>> children()

Description copied from interface: AccState

Sub-accumulators must be enumerated in the correct order.
