frameListener
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets the listener of inbound frames. This listener will only be set if the decoder's listener isnull
. -
gracefulShutdownTimeoutMillis
public Http2ConnectionHandlerBuilder gracefulShutdownTimeoutMillis(long gracefulShutdownTimeoutMillis) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets the graceful shutdown timeout of theHttp2Connection
in milliseconds. -
server
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets ifAbstractHttp2ConnectionHandlerBuilder.build()
will to create aHttp2Connection
in server mode (true
) or client mode (false
).- Overrides:
server
in classAbstractHttp2ConnectionHandlerBuilder<Http2ConnectionHandler,
Http2ConnectionHandlerBuilder>
-
connection
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets theHttp2Connection
to use. -
maxReservedStreams
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Set the maximum number of streams which can be in the reserved state at any given time. -
codec
public Http2ConnectionHandlerBuilder codec(Http2ConnectionDecoder decoder, Http2ConnectionEncoder encoder) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets theHttp2ConnectionDecoder
andHttp2ConnectionEncoder
to use.- Overrides:
codec
in classAbstractHttp2ConnectionHandlerBuilder<Http2ConnectionHandler,
Http2ConnectionHandlerBuilder>
-
frameLogger
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets the logger that is used for the encoder and decoder. -
encoderEnforceMaxConcurrentStreams
public Http2ConnectionHandlerBuilder encoderEnforceMaxConcurrentStreams(boolean encoderEnforceMaxConcurrentStreams) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets if the encoder should queue frames if the maximum number of concurrent streams would otherwise be exceeded. -
encoderIgnoreMaxHeaderListSize
public Http2ConnectionHandlerBuilder encoderIgnoreMaxHeaderListSize(boolean encoderIgnoreMaxHeaderListSize) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets if the SETTINGS_MAX_HEADER_LIST_SIZE should be ignored when encoding headers.- Overrides:
encoderIgnoreMaxHeaderListSize
in classAbstractHttp2ConnectionHandlerBuilder<Http2ConnectionHandler,
Http2ConnectionHandlerBuilder> - Parameters:
encoderIgnoreMaxHeaderListSize
-true
to ignore SETTINGS_MAX_HEADER_LIST_SIZE.- Returns:
- this.
-

decoupleCloseAndGoAway
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Determine if theChannelOutboundInvoker.close()
should be coupled with goaway and graceful close.- Overrides:
decoupleCloseAndGoAway
in classAbstractHttp2ConnectionHandlerBuilder<Http2ConnectionHandler,
Http2ConnectionHandlerBuilder> - Parameters:
decoupleCloseAndGoAway
-true
to makeChannelOutboundInvoker.close()
directly close the underlying transport, and not attempt graceful closure via GOAWAY.- Returns:
this
.
-
flushPreface
Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Determine if the Preface should be automatically flushed when theChannel
becomes active or not.Client may choose to opt-out from this automatic behavior and manage flush manually if it's ready to send request frames immediately after the preface. It may help to avoid unnecessary latency.
- Overrides:
flushPreface
in classAbstractHttp2ConnectionHandlerBuilder<Http2ConnectionHandler,
Http2ConnectionHandlerBuilder> - Parameters:
flushPreface
-true
to automatically flush,false otherwise
.- Returns:
this

decoderEnforceMaxConsecutiveEmptyDataFrames
public int decoderEnforceMaxConsecutiveEmptyDataFrames()Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Returns the maximum number of consecutive empty DATA frames (without end_of_stream flag) that are allowed before the connection is closed. This allows to protect against the remote peer flooding us with such frames and so use up a lot of CPU. There is no valid use-case for empty DATA frames without end_of_stream flag.0
means no protection is in place. -
decoderEnforceMaxConsecutiveEmptyDataFrames
public Http2ConnectionHandlerBuilder decoderEnforceMaxConsecutiveEmptyDataFrames(int maxConsecutiveEmptyFrames) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets the maximum number of consecutive empty DATA frames (without end_of_stream flag) that are allowed before the connection is closed. This allows to protect against the remote peer flooding us with such frames and so use up a lot of CPU. There is no valid use-case for empty DATA frames without end_of_stream flag.0
means no protection should be applied. -
decoderEnforceMaxRstFramesPerWindow
public Http2ConnectionHandlerBuilder decoderEnforceMaxRstFramesPerWindow(int maxRstFramesPerWindow, int secondsPerWindow) Description copied from class:AbstractHttp2ConnectionHandlerBuilder
Sets the maximum number RST frames that are allowed per window before the connection is closed. This allows to protect against the remote peer flooding us with such frames and so use up a lot of CPU.0
for any of the parameters means no protection should be applied. -
