fromArray()

Create an Exemplar from a normalized array representation.


    public
            static        fromArray(array{value: float|int, timestamp: string, traceId: array{hex: string}, spanId: array{hex: string}, filteredAttributes: array} $data) : self

Parameters

$data : array{value: float|int, timestamp: string, traceId: array{hex: string}, spanId: array{hex: string}, filteredAttributes: array}: Normalized Exemplar data

Return values

self

normalize()
