get

public Object get(String column)

Specified by:

get in interface TupleSnapshot

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface TupleSnapshot

getColumnNames

public Set<String> getColumnNames()

Specified by:

getColumnNames in interface TupleSnapshot

getNode

public org.neo4j.graphdb.Node getNode()

setNode

public void setNode(org.neo4j.graphdb.Node node)

isNew

public boolean isNew()

Whether this snapshot has been newly created (meaning it doesn't have an actual Node yet) or not. A node will be in the "new" state between the createTuple() call and the next insertOrUpdateTuple() call.
