Method Detail

init

@Deprecated
public void init(java.util.function.UnaryOperator<Parser.Listener> wrapper)

Deprecated.

init

public void init(Parser.Listener listener)

rateControlOnEvent

public boolean rateControlOnEvent(java.lang.Object event)

getListener

protected Parser.Listener getListener()

getHpackDecoder

public HpackDecoder getHpackDecoder()

reset

private void reset()

parse

public void parse(java.nio.ByteBuffer buffer)

Parses the given buffer bytes and emit events to a Parser.Listener.

When this method returns, the buffer may not be fully consumed, so invocations to this method should be wrapped in a loop:

 while (buffer.hasRemaining())
     parser.parse(buffer);
 

Parameters:

buffer - the buffer to parse

parseHeader

protected boolean parseHeader(java.nio.ByteBuffer buffer)

parseBody

protected boolean parseBody(java.nio.ByteBuffer buffer)

connectionFailure

private boolean connectionFailure(java.nio.ByteBuffer buffer,
                                  ErrorCode error,
                                  java.lang.String reason)

getFrameType

protected int getFrameType()

hasFlag

protected boolean hasFlag(int bit)

getMaxFrameLength

@Deprecated
public int getMaxFrameLength()

Deprecated.

setMaxFrameLength

@Deprecated
public void setMaxFrameLength(int maxFrameSize)

Deprecated.

getMaxFrameSize

public int getMaxFrameSize()

setMaxFrameSize

public void setMaxFrameSize(int maxFrameSize)

getMaxSettingsKeys

public int getMaxSettingsKeys()

setMaxSettingsKeys
