Properties

crowdingTag → IndexDatapoint_CrowdingTag?
Optional. CrowdingTag of the datapoint, the number of neighbors to return in each crowding can be configured during query.
final
datapointId → String
Required. Unique identifier of the datapoint.
final
embeddingMetadata → Struct?
Optional. The key-value map of additional metadata for the datapoint.
final
featureVector → List<double>
Required. Feature embedding vector for dense index. An array of numbers with the length of NearestNeighborSearchConfig.dimensions.
final
hashCode → int

no setterinherited
numericRestricts → List<IndexDatapoint_NumericRestriction>
Optional. List of Restrict of the datapoint, used to perform "restricted searches" where boolean rule are used to filter the subset of the database eligible for matching. This uses numeric comparisons.
final
qualifiedName → String
The fully qualified name of this message, i.e., google.protobuf.Duration or google.rpc.ErrorInfo.

restricts → List<IndexDatapoint_Restriction>
Optional. List of Restrict of the datapoint, used to perform "restricted searches" where boolean rule are used to filter the subset of the database eligible for matching. This uses categorical tokens. See: https://cloud.google.com/vertex-ai/docs/matching-engine/filtering
final
runtimeType → Type
A representation of the runtime type of the object.
