Interface AccStateGon<I,E,K,V>

Type Parameters:

I - Input type (e.g. Binding)

E - Environment type (such as FunctionEnv, ExecutionContext)

K - Type of fields in object output

V - Type of primitives in object output

All Superinterfaces:

AccState<I,E>

public interface AccStateGon<I,E,K,V>
extends AccState<I,E>

AccState for producing generalized object notation (gon) structures.

Method Summary

Modifier and Type	Method	Description
Iterator<? extends AccStateGon<I,E,K,V>>	children()	Sub-accumulators must be enumerated in the correct order.
GonType	getGonType()	The GON type which this accumulator produces.
AccStateGon<I,E,K,V>	getParent()	The immediate parent of this AccState.
default AccStateGon<I,E,K,V>	getRoot()	The ancestor to which to attach produced values.
void	setContext(AccContext<K,V> context)	The state to which to backtrack if an input cannot be processed by the current state
void	setParent(AccStateGon<I,E,K,V> parent)
AccStateGon<I,E,K,V>	transition(Object inputStateId, I input, E env)	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.

Method Details

getParent

AccStateGon<I,E,K,V> getParent()

The immediate parent of this AccState.

Specified by:

getParent in interface AccState<I,E>

getGonType

GonType getGonType()

The GON type which this accumulator produces.

getRoot

default AccStateGon<I,E,K,V> getRoot()

The ancestor to which to attach produced values.

Specified by:

getRoot in interface AccState<I,E>

setParent

void setParent(AccStateGon<I,E,K,V> parent)

setContext

void setContext(AccContext<K,V> context)

The state to which to backtrack if an input cannot be processed by the current state

transition

AccStateGon<I,E,K,V> transition(Object inputStateId,
 I input,
 E env)
                         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.

Specified by:

transition in interface AccState<I,E>

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).

Returns:

Throws:

IOException

children

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

Description copied from interface: AccState

Sub-accumulators must be enumerated in the correct order.

Specified by:

children in interface AccState<I,E>
