Method Details

create

public static Http2StreamManager create(Http2StreamManagerOptions options)

Factory function for Http2StreamManager instances

Parameters:

options - configuration options

Returns:

a new instance of an Http2StreamManager

acquireStream

public CompletableFuture<Http2Stream> acquireStream(Http2Request request,
 HttpStreamBaseResponseHandler streamHandler)

Request a Http2Stream from StreamManager.

Parameters:

request - The Request to make to the Server.

streamHandler - The Stream Handler to be called from the Native EventLoop

Returns:

A future for a Http2Stream that will be completed when the stream is acquired.

acquireStream

public CompletableFuture<Http2Stream> acquireStream(Http2Request request,
 HttpStreamBaseResponseHandler streamHandler,
 boolean useManualDataWrites)

Request a Http2Stream from StreamManager.

Parameters:

request - The Request to make to the Server.

streamHandler - The Stream Handler to be called from the Native EventLoop

useManualDataWrites - When true, request body data is provided via HttpStreamBase.writeData(byte[], boolean, software.amazon.awssdk.crt.http.HttpStreamBase.HttpStreamWriteDataCompletionCallback) instead of from the request's HttpRequestBodyStream. See Http2ClientConnection.makeRequest(HttpRequestBase, HttpStreamBaseResponseHandler, boolean) for caveats on combining a body stream with manual writes.

Returns:

A future for a Http2Stream that will be completed when the stream is acquired.

getMaxConnections

public int getMaxConnections()

Returns:

maximum number of connections this connection manager will pool

getManagerMetrics

public HttpManagerMetrics getManagerMetrics()

Returns:

concurrency metrics for the current manager

getShutdownCompleteFuture

public CompletableFuture<Void> getShutdownCompleteFuture()
