Method Detail

persist

DegreeQuery<String> persist()

Persist the result in the graph after executing the query. Be default, the degree is saved as a resource of the vertex, with resource type name "degree".

Returns:

a DegreeQuery with persist flag set

persist

DegreeQuery<String> persist(String resourceTypeName)

Persist the result in the graph after executing the query. The degree is saved as a resource of the vertex.

Parameters:

resourceTypeName - the name of the resource type to save the degree

Returns:

a DegreeQuery with persist flag and customised resource type name set

in

DegreeQuery<T> in(String... subTypeNames)

Specified by:

in in interface ComputeQuery<T>

Parameters:

subTypeNames - an array of types to include in the subgraph

Returns:

a DegreeQuery with the subTypeNames set

in

DegreeQuery<T> in(Collection<String> subTypeNames)

Specified by:

in in interface ComputeQuery<T>

Parameters:

subTypeNames - a collection of types to include in the subgraph

Returns:

a DegreeQuery with the subTypeNames set

of

DegreeQuery<T> of(String... ofTypeNames)

Parameters:

ofTypeNames - an array of types in the subgraph to compute degree of. By default the degrees of all the types in the graph will be computed

Returns:

a DegreeQuery with the subTypeNames set

of

DegreeQuery<T> of(Collection<String> ofTypeNames)

Parameters:

ofTypeNames - a collection of types in the subgraph to compute degree of. By default the degrees of all the types in the graph will be computed

withGraph

DegreeQuery<T> withGraph(GraknGraph graph)

Specified by:

withGraph in interface ComputeQuery<T>

Specified by:

withGraph in interface Query<T>

Parameters:

graph - the graph to execute the query on

Returns:

a DegreeQuery with the graph set
