 AccJsonEdge[] edgeAccs)

Method Details

of

public static AccJsonFragmentBody of(Map<org.apache.jena.graph.Node,Integer> fieldIdToIndex,
 AccJsonEdge[] edgeAccs)

Create a new instance and set it as the parent on all the property accumulators

begin

public void begin(org.apache.jena.graph.Node source,
 AccContextRdf context,
 boolean skipOutput)
           throws IOException

Description copied from interface: AccJson

Start accumulation based on a given node in the underlying graph. Calls cannot be nested.

Specified by:

begin in interface AccJson

Overrides:

begin in class AccJsonBase

Parameters:

source - The source node to which the next incoming edge(s) will connect to

context - The context which holds the JSON serializers

skipOutput - When output should be disabled (used e.g. to skip over lists of items where just one was expected)

Throws:

IOException

transition

public AccJson transition(org.apache.jena.graph.Triple input,
 AccContextRdf context)
                   throws IOException

Description copied from interface: AccJson

Process an edge. Based on the given edge, this accumulator attempts to transition to another AccJson instance and return it. If there is no valid transition then this method returns null.

Throws:

IOException

end

public void end(AccContextRdf context)
         throws IOException

Description copied from interface: AccJson

End the accumulator's current node

Specified by:

end in interface AccJson

Overrides:

end in class AccJsonBase

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
