Method Detail

injectBaggage

protected void injectBaggage(io.opentracing.propagation.TextMap carrier,
                             java.lang.String key,
                             java.lang.String value)

Injects one baggage item to the carrier. Sub-class is responsible of providing exactly this key/value once AbstractPropagator.extractBaggage(Object) is called, but can wrap the key/value in what ever they want.

Specified by:

injectBaggage in class AbstractPropagator<io.opentracing.propagation.TextMap>

Parameters:

carrier - carrier

key - key

value - value

extractBaggage

protected java.lang.Iterable<java.util.Map.Entry<java.lang.String,java.lang.String>> extractBaggage(io.opentracing.propagation.TextMap carrier)

Gets all baggage (not only tracing related) from the carrier. For example the HTTP carrier would here provide all headers. Subclasses can deal here with additional operations as encoding.

Specified by:

extractBaggage in class AbstractPropagator<io.opentracing.propagation.TextMap>

Parameters:

carrier - carrier

Returns:
