@Generated("software.amazon.awssdk:codegen") public final class RDFGraphSummary extends Object implements SdkPojo, Serializable, ToCopyableBuilder<RDFGraphSummary.Builder,RDFGraphSummary>

The RDF graph summary API returns a read-only list of classes and predicate keys, along with counts of quads, subjects, and predicates.

  • Method Details

    • 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.

    • toBuilder

      public RDFGraphSummary.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<RDFGraphSummary.Builder,RDFGraphSummary>
      Returns:
      a builder for type T

    • builder

      public static RDFGraphSummary.Builder builder()

    • serializableBuilderClass

      public static Class<? extends RDFGraphSummary.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
