Method Detail

reset

protected void reset()

public int getMaxKeys()

emptyBody

protected void emptyBody(java.nio.ByteBuffer buffer)

Overrides:

emptyBody in class BodyParser

validateFrame

private boolean validateFrame(java.nio.ByteBuffer buffer,
                              int streamId,
                              int bodyLength)

parse

public boolean parse(java.nio.ByteBuffer buffer)

Description copied from class: BodyParser

Parses the body bytes in the given buffer; only the body bytes are consumed, therefore when this method returns, the buffer may contain unconsumed bytes.

Specified by:

parse in class BodyParser

Parameters:

buffer - the buffer to parse

Returns:

true if the whole body bytes were parsed, false if not enough body bytes were present in the buffer

parse

private boolean parse(java.nio.ByteBuffer buffer,
                      int streamId,
                      int bodyLength)

onSetting

protected boolean onSetting(java.nio.ByteBuffer buffer,
                            java.util.Map<java.lang.Integer,java.lang.Integer> settings,
                            int key,
                            int value)

onSettings

protected boolean onSettings(java.nio.ByteBuffer buffer,
                             java.util.Map<java.lang.Integer,java.lang.Integer> settings)

onSettings

private boolean onSettings(java.nio.ByteBuffer buffer,
                           SettingsFrame frame)

parseBody

public static SettingsFrame parseBody(java.nio.ByteBuffer buffer)

Parses the given buffer containing the whole body of a SETTINGS frame (without header bytes), typically from the HTTP2-Settings header.

Parameters:

buffer - the buffer containing the body of SETTINGS frame

Returns:

the SETTINGS frame from the parsed body bytes
