class MetricCollector : public opentelemetry::sdk::metrics::MetricProducer, public opentelemetry::sdk::metrics::CollectorHandle 

An internal opaque interface that the MetricReader receives as MetricProducer. It acts as the storage key to the internal metric stream state for each MetricReader.

Public Functions

~MetricCollector() override = default

AggregationTemporality GetAggregationTemporality(InstrumentType instrument_type) noexcept override

virtual bool Collect(nostd::function_ref<bool(ResourceMetrics &metric_data)> callback) noexcept override

The callback to be called for each metric exporter. This will only be those metrics that have been produced since the last time this method was called.

Returns:: a status of completion of method.
