Method Details

convertKeyValueListToMap

public static Map<String,String> convertKeyValueListToMap(List<String> headers)

Converts a list of "key=value" pairs into a map. Empty entries will be removed. In case of duplicate keys, the latest takes precedence.

Parameters:

headers - nullable list of "key=value" pairs

Returns:

non-null map of key-value pairs

setMDCData

public static void setMDCData(io.opentelemetry.context.Context otelContext,
 io.vertx.core.Context vertxContext)

Sets MDC data by using the current span from the otelContext.

This method is in the hot path and was optimized to not use getSpanData()

Parameters:

otelContext - opentelemetry otelContext

vertxContext - vertx otelContext

getSpanData

public static Map<String,String> getSpanData(io.opentelemetry.context.Context context)

Gets current span data from the MDC context.

Parameters:

context - opentelemetry context

clearMDCData

public static void clearMDCData(io.vertx.core.Context vertxContext)

Clears MDC data related to OpenTelemetry

Parameters:

vertxContext - vertx context
