beginActual

public void beginActual()
                 throws IOException

Sets the source node which subsequent triples must match in addition to the fieldId. This method should be called by the owner of the edge such as AccJsonObject.

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 an input tuple (usually binding) 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.
