getAttributes

public io.opentelemetry.api.common.Attributes getAttributes(E1 dimension1,
 E2 dimension2,
 E3 dimension3,
 E4 dimension4)

Manages the nested EnumMap structure for lazy initialization of Attributes. The structure is a Four-level nested EnumMap: EnumMap<E1, EnumMap<E2, EnumMap<E3, EnumMap<E4, Attributes>>>>. This allows efficient retrieval of Attributes based on Four enum dimensions (E1, E2, E3, E4). For thread safety considerations, refer MetricEntityStateOneEnum.getAttributes(E).
