public class StreamParser
- extends java.lang.Object
Constructor Summary |
StreamParser(int parserType,
DataListener listener,
java.lang.Object listenerData)
Constructs a ThinkGear parser object of the given @c parserType,
and registers the given @c listener. |
Method Summary |
static float |
bigEndianBytesToFloat(byte[] bytes)
Assuming the @c bytes array contains the 4 bytes of an IEEE 754
floating point number in network byte order (big-endian), this
function returns the corresponding Java floating point number. |
int |
parseByte(int b)
Parses the byte @b as part of a ThinkGear data stream. |

StreamParser
public StreamParser(int parserType,
DataListener listener,
java.lang.Object listenerData)
- Constructs a ThinkGear parser object of the given @c parserType,
and registers the given @c listener.
- Parameters:
parserType
- One of the PARSER_TYPE_* constants, either:
PARSER_TYPE_PACKETS (ThinkGear-EM)
PARSER_TYPE_2BYTERAW (legacy 5V support only)listener
- An object that implements the ThinkGearListener
interface, which implements the dataValueReceived()
event handler (callback method).listenerData
- Any arbitrary object that should be passed to the
dataValueReceived() method as well. This parameter
is ot really necessary in Java, but is included
here for consistency with the C implementation of
this StreamParser class.
parseByte
public int parseByte(int b)
- Parses the byte @b as part of a ThinkGear data stream.
- Parameters:
b
- The byte from the ThinkGear data stream to parse.
- Returns:
- -2 if a complete Packet was received, but the checksum failed.
bigEndianBytesToFloat
public static float bigEndianBytesToFloat(byte[] bytes)
- Assuming the @c bytes array contains the 4 bytes of an IEEE 754
floating point number in network byte order (big-endian), this
function returns the corresponding Java floating point number.
- Parameters:
bytes
- An array of 4 bytes corresponding to the 4 bytes
of an IEEE 754 floating point number in network
byte order (big-endian).
- Returns:
- The Java floating point number corresponding to the
IEEE 754 floating poing number in @c bytes.
