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,
 VeniceOpenTelemetryMetricsRepository otelRepository,
 MetricEntityState.TehutiSensorRegistrationFunction registerTehutiSensorFn,
 TehutiMetricNameEnum tehutiMetricNameEnum,
 List<io.tehuti.metrics.MeasurableStat> tehutiMetricStats,
 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).

record

public void record(long value,
 E1 dimension1,
 E2 dimension2,
 E3 dimension3)

record

public void record(double value,
 E1 dimension1,
 E2 dimension2,
 E3 dimension3)

getAttributesEnumMap

public EnumMap<E1,EnumMap<E2,EnumMap<E3,io.opentelemetry.api.common.Attributes>>> getAttributesEnumMap()
