Class AccStateArrayInit<I,E,K,V>

java.lang.Object

org.aksw.jenax.graphql.sparql.v2.acc.state.api.AccStateBase<I,E,K,V>

org.aksw.jenax.graphql.sparql.v2.acc.state.api.impl.AccStateArrayInit<I,E,K,V>

All Implemented Interfaces:

AccState<I,E>, AccStateGon<I,E,K,V>, AccStateTypeNonObject<I,E,K,V>

public class AccStateArrayInit<I,E,K,V>
extends AccStateBase<I,E,K,V>
implements AccStateTypeNonObject<I,E,K,V>

AccState for yielding a sequence of items without enclosing them in an array; because the array would be a single object-notation entity on its own. This is needed for streaming the individual items of a multi-valued top-level field.

Method Details

getGonType

public GonType getGonType()

Description copied from interface: AccStateGon

The GON type which this accumulator produces.

Specified by:

getGonType in interface AccStateGon<I,E,K,V>

getMatchStateId

public Object getMatchStateId()

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 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.

Specified by:

children in interface AccState<I,E>

Specified by:
