Method Detail

results

List<Map<VarName,Concept>> results()

Get a list of results. This differs from MatchQuery#execute because the keys are instances of VarName.

Returns:

a list of results

streamWithVarNames

java.util.stream.Stream<Map<VarName,Concept>> streamWithVarNames()

Get a stream of results. This differs from MatchQuery#execute because the keys are instances of VarName.

Returns:

a stream of results

streamWithAnswers

java.util.stream.Stream<Answer> streamWithAnswers()

Get a stream of answers. This differs from MatchQuery#execute because it returns a stream of Answer objects containing the original map with VarName as key.

Returns:

a stream of answers

getTypes

Set<Type> getTypes(GraknGraph graph)

Parameters:

graph - the graph to use to get types from

Returns:

all concept types referred to explicitly in the query

getTypes

Set<Type> getTypes()

Returns:

all concept types referred to explicitly in the query

getPattern

Conjunction<PatternAdmin> getPattern()

Returns:

the pattern to match in the graph

getGraph

Optional<GraknGraph> getGraph()

Returns:

the graph the query operates on, if one was provided

getSelectedNames

Set<VarName> getSelectedNames()

Returns:

all selected variable names in the query
