Method Detail

numDistinctSubjects

public final Long numDistinctSubjects()

The number of distinct subjects in the graph.

Returns:

The number of distinct subjects in the graph.

numDistinctPredicates

public final Long numDistinctPredicates()

The number of distinct predicates in the graph.

Returns:

The number of distinct predicates in the graph.

numQuads

public final Long numQuads()

The number of quads in the graph.

Returns:

The number of quads in the graph.

numClasses

public final Long numClasses()

The number of classes in the graph.

Returns:

The number of classes in the graph.

hasClasses

public final boolean hasClasses()

For responses, this returns true if the service returned a value for the Classes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

classes

public final List<String> classes()

A list of the classes in the graph.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasClasses() method.

Returns:

A list of the classes in the graph.

hasPredicates

public final boolean hasPredicates()

For responses, this returns true if the service returned a value for the Predicates property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

predicates

public final List<Map<String,Long>> predicates()

"A list of predicates in the graph, along with the predicate counts.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPredicates() method.

Returns:

"A list of predicates in the graph, along with the predicate counts.

hasSubjectStructures

public final boolean hasSubjectStructures()

For responses, this returns true if the service returned a value for the SubjectStructures property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

subjectStructures

public final List<SubjectStructure> subjectStructures()

This field is only present when the request mode is DETAILED. It contains a list of subject structures.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSubjectStructures() method.

Returns:

This field is only present when the request mode is DETAILED. It contains a list of subject structures.
