setInputBufferSizeback to summary
public void setInputBufferSize(int inputBufferSize)

Sets the size of the buffer used for QUIC network reads.

Default value is 2048 bytes.

Parameters
inputBufferSize:int

the buffer size in bytes

setMaxBlockedStreamsback to summary
public void setMaxBlockedStreams(int maxBlockedStreams)

Sets the local QPACK decoder max number of blocked streams.

The default value is 64.

This value is configured in the local QPACK decoder, and then communicated to the remote QPACK encoder via the SETTINGS frame.

Parameters
maxBlockedStreams:int

the QPACK decoder max blocked streams

setMaxDecoderTableCapacityback to summary
public void setMaxDecoderTableCapacity(int maxTableCapacity)

Sets the local QPACK decoder max dynamic table capacity.

The default value is 65536 bytes.

This value is configured on the local QPACK decoder, and then communicated to the remote QPACK encoder via the SETTINGS frame.

Parameters
maxTableCapacity:int

the QPACK decoder dynamic table max capacity

See Also
setMaxEncoderTableCapacity(int)
setMaxEncoderTableCapacityback to summary
public void setMaxEncoderTableCapacity(int maxTableCapacity)

Sets the local QPACK encoder initial dynamic table capacity.

The default value is 65536 bytes.

This value is configured in the local QPACK encoder, and may be overwritten by a smaller value received via the SETTINGS frame.

Parameters
maxTableCapacity:int

the QPACK encoder dynamic table initial capacity

See Also
setMaxDecoderTableCapacity(int)
setMaxRequestHeadersSizeback to summary
public void setMaxRequestHeadersSize(int maxRequestHeadersSize)

Sets max request headers size.

The default value is 8192 bytes.

This value is configured in the server-side QPACK decoder, and then communicated to the client-side QPACK encoder via the SETTINGS frame.

The client-side QPACK encoder uses this value to cap, if necessary, the value sent by the server-side QPACK decoder.

Parameters
maxRequestHeadersSize:int

the max request headers size in bytes

setMaxResponseHeadersSizeback to summary
public void setMaxResponseHeadersSize(int maxResponseHeadersSize)

Sets max response headers size.

The default value is 8192 bytes.

This value is configured in the client-side QPACK decoder, and then communicated to the server-side QPACK encoder via the SETTINGS frame.

The server-side QPACK encoder uses this value to cap, if necessary, the value sent by the client-side QPACK decoder.

Parameters
maxResponseHeadersSize:int

the max response headers size

setOutputBufferSizeback to summary
public void setOutputBufferSize(int outputBufferSize)

Sets the size of the buffer used for QUIC network writes.

Default value is 2048 bytes.

Parameters
outputBufferSize:int

the buffer size in bytes

setStreamIdleTimeoutback to summary
public void setStreamIdleTimeout(long streamIdleTimeout)

Sets the stream idle timeout in milliseconds.

Negative values and zero mean that the stream never times out.

Default value is 30 seconds.

Parameters
streamIdleTimeout:long

the stream idle timeout in milliseconds

setUseInputDirectByteBuffersback to summary
public void setUseInputDirectByteBuffers(boolean useInputDirectByteBuffers)

setUseOutputDirectByteBuffersback to summary
public void setUseOutputDirectByteBuffers(boolean useOutputDirectByteBuffers)

Sets whether to use direct buffers for QUIC network writes.

Default value is true.

Parameters
