Method Detail

addHeaderFromStringback to summary
private void addHeaderFromString(String headerString) throws ProtocolException
canContinueParsingback to summary
private boolean canContinueParsing(ByteBuffer buffer)
checkMaxHeaderSizeback to summary
private void checkMaxHeaderSize(int sz) throws ProtocolException
currentStateMessageback to summary
public String currentStateMessage()

A current-state message suitable for inclusion in an exception detail message.

getback to summary
private char get(ByteBuffer input)

Returns a character (char) corresponding to the next byte in the input, interpreted as an ISO-8859-1 encoded character.

The ISO-8859-1 encoding is a 8-bit character coding that corresponds to the first 256 Unicode characters - from U+0000 to U+00FF. UTF-16 is backward compatible with ISO-8859-1 - which means each byte in the input should be interpreted as an unsigned value from [0, 255] representing the character code.

Parameters
input:ByteBuffer

a ByteBuffer containing a partial input

Returns:char

the next byte in the input, interpreted as an ISO-8859-1 encoded char

Exceptions
BufferUnderflowException:
if the input buffer's current position is not smaller than its limit
headersback to summary
pack-priv HttpHeaders headers()

Returns the headers, possibly empty.

maybeEndHeadersback to summary
private void maybeEndHeaders(ByteBuffer input) throws ProtocolException
maybeStartHeadersback to summary
private void maybeStartHeaders(ByteBuffer input) throws ProtocolException
newSizeback to summary
private static long newSize(long size, int name, int value) throws ProtocolException
parseback to summary
pack-priv boolean parse(ByteBuffer input) throws ProtocolException

Parses HTTP/1.X status-line and headers from the given bytes. Must be called successive times, with additional data, until returns true. All given ByteBuffers will be consumed, until ( possibly ) the last one ( when true is returned ), which may not be fully consumed.

Parameters
input:ByteBuffer

the ( partial ) header data

Returns:boolean

true iff the end of the headers block has been reached
