Class AccStateLiteral<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.AccStateLiteral<I,E,K,V>

All Implemented Interfaces:

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

public class AccStateLiteral<I,E,K,V>
extends AccStateBase<I,E,K,V>
implements AccStateTypeProduceNode<I,E,K,V>

AccStateLiteral: Extracts a value from the input and forwards it to the writer. ValueParent must be 'entry' or 'array. Always accepts the current state. (Matches the same stateId as the parent) Never transitions into a new state.
