requiredOffloads

public HttpExecutionStrategy requiredOffloads()

Description copied from interface: HttpExecutionStrategyInfluencer

Return an ExecutionStrategy that describes the offloads required by the influencer.

The provided default implementation requests offloading of all operations. Implementations that require no offloading should be careful to return HttpExecutionStrategies.offloadNone() rather than HttpExecutionStrategies.offloadNever(). Implementations should avoid returning HttpExecutionStrategies.defaultStrategy(), instead returning the strategy they require or HttpExecutionStrategies.offloadAll() if offloading for all paths is required (safe default).
