Method Summary

Modifier and Type	Method	Description
void	begin(Object stateId, I parentInput, E env, boolean skipOutput)	FIXME What exactly is id? Is it the value by which this acc connects to the parent? The context and skipOutput flag are stored on the accumulator until end is called.
Iterator<? extends AccState<I,E>>	children()	Sub-accumulators must be enumerated in the correct order.
void	end()
AccState<I,E>	getParent()
default AccState<I,E>	getRoot()
Object	getStateId()	Get the id of the state for which this accumulator is notified.
boolean	hasBegun()
AccState<I,E>	transition(Object inputStateId, I binding, E env)

Method Details

getParent

AccState<I,E> getParent()

getRoot

default AccState<I,E> getRoot()

getStateId

Object getStateId()

Get the id of the state for which this accumulator is notified.

begin

void begin(Object stateId,
 I parentInput,
 E env,
 boolean skipOutput)
    throws IOException

FIXME What exactly is id? Is it the value by which this acc connects to the parent? The context and skipOutput flag are stored on the accumulator until end is called.

Throws:

IOException

hasBegun

boolean hasBegun()

transition

AccState<I,E> transition(Object inputStateId,
 I binding,
 E env)
                  throws IOException

Parameters:

inputStateId - The stateId, typically extracted from the input by the driver. (Rationale: Only the driver needs to know how to extract the state from an input).

binding -

env -

Returns:

Throws:

IOException

end

void end()
  throws IOException

Throws:

IOException

children

Iterator<? extends AccState<I,E>> children()

Sub-accumulators must be enumerated in the correct order.
