Module contents¶

class opentelemetry.propagators.composite.CompositePropagator(propagators)[source]¶

Bases: opentelemetry.propagators.textmap.TextMapPropagator

CompositePropagator provides a mechanism for combining multiple propagators into a single one.

Parameters: propagators (Sequence[TextMapPropagator]) – the list of propagators to use

extract(carrier, context=None, getter=<opentelemetry.propagators.textmap.DefaultGetter object>)[source]¶

Run each of the configured propagators with the given context and carrier. Propagators are run in the order they are configured, if multiple propagators write the same context key, the propagator later in the list will override previous propagators.

See opentelemetry.propagators.textmap.TextMapPropagator.extract

Return type: Context

inject(carrier, context=None, setter=<opentelemetry.propagators.textmap.DefaultSetter object>)[source]¶

Run each of the configured propagators with the given context and carrier. Propagators are run in the order they are configured, if multiple propagators write the same carrier key, the propagator later in the list will override previous propagators.

See opentelemetry.propagators.textmap.TextMapPropagator.inject

Return type: None

property fields¶

Returns a set with the fields set in inject.

See opentelemetry.propagators.textmap.TextMapPropagator.fields

Return type: Set[str]

class opentelemetry.propagators.composite.CompositeHTTPPropagator(propagators)[source]¶

Bases: opentelemetry.propagators.composite.CompositePropagator

CompositeHTTPPropagator provides a mechanism for combining multiple propagators into a single one.
