Method Summary

Modifier and Type	Method	Description
void	acceptContribution(RdfElement value, AccContextRdf context)	For materialization: Whenever end() is called on a state with materialization enabled, then it passes its accumulated value to the parent using this method.
void	begin(org.apache.jena.graph.Node node, AccContextRdf context, boolean skipOutput)	Start accumulation based on a given node in the underlying graph.
void	end(AccContextRdf context)	End the accumulator's current node
org.aksw.commons.path.json.PathJson	getPath()
String	toString()
AccJson	transition(org.apache.jena.graph.Triple edge, AccContextRdf context)	Process an edge.

Method Details

getPath

public org.aksw.commons.path.json.PathJson getPath()

Specified by:

getPath in interface AccJson

begin

public void begin(org.apache.jena.graph.Node node,
 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:

node - 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 edge,
 AccContextRdf context)

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.

Specified by:

transition in interface AccJson

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

acceptContribution

public void acceptContribution(RdfElement value,
 AccContextRdf context)

Description copied from interface: AccJson

For materialization: Whenever end() is called on a state with materialization enabled, then it passes its accumulated value to the parent using this method.

Specified by:

acceptContribution in interface AccJson
