Method Details

create

public StreamingHttpClientFilter create(FilterableStreamingHttpClient client)

Description copied from interface: StreamingHttpClientFilterFactory

Creates a StreamingHttpClientFilter using the provided StreamingHttpClientFilter.

Specified by:

create in interface StreamingHttpClientFilterFactory

Parameters:

client - FilterableStreamingHttpClient to filter

Returns:

StreamingHttpClientFilter using the provided StreamingHttpClientFilter.

create

public StreamingHttpConnectionFilter create(FilterableStreamingHttpConnection connection)

Description copied from interface: StreamingHttpConnectionFilterFactory

Create a StreamingHttpConnectionFilter using the provided FilterableStreamingHttpConnection.

Specified by:

create in interface StreamingHttpConnectionFilterFactory

Parameters:

connection - FilterableStreamingHttpConnection to filter

Returns:

StreamingHttpConnectionFilter using the provided FilterableStreamingHttpConnection.

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).

Specified by:

requiredOffloads in interface ExecutionStrategyInfluencer<HttpExecutionStrategy>

Specified by:

requiredOffloads in interface HttpExecutionStrategyInfluencer

Returns:

the ExecutionStrategy required by the influencer.
