Method Details

create

public static <E1 extends Enum<E1> & VeniceDimensionInterface,
E2 extends Enum<E2> & VeniceDimensionInterface,
E3 extends Enum<E3> & VeniceDimensionInterface>
MetricEntityStateThreeEnums<E1,E2,E3> create(MetricEntity metricEntity,
 VeniceOpenTelemetryMetricsRepository otelRepository,
 Map<VeniceMetricsDimensions,String> baseDimensionsMap,
 Class<E1> enumTypeClass1,
 Class<E2> enumTypeClass2,
 Class<E3> enumTypeClass3)

Factory method with named parameters to ensure the passed in enumTypeClass are in the same order as E

create

public static <E1 extends Enum<E1> & VeniceDimensionInterface,
E2 extends Enum<E2> & VeniceDimensionInterface,
E3 extends Enum<E3> & VeniceDimensionInterface>
MetricEntityStateThreeEnums<E1,E2,E3> create(MetricEntity metricEntity,

 Map<VeniceMetricsDimensions,String> baseDimensionsMap,
 Class<E1> enumTypeClass1,
 Class<E2> enumTypeClass2,
 Class<E3> enumTypeClass3)

Overloaded Factory method for constructor with Tehuti parameters

getAttributes

public io.opentelemetry.api.common.Attributes getAttributes(E1 dimension1,
 E2 dimension2,
 E3 dimension3)

Manages the nested EnumMap structure for lazy initialization of Attributes. The structure is a three-level nested EnumMap: EnumMap<E1, EnumMap<E2, EnumMap<E3, Attributes>>>. This allows efficient retrieval of Attributes based on three enum dimensions (E1, E2, E3). For thread safety considerations, refer MetricEntityStateOneEnum.getAttributes(E).
