Method Detail

getUShort

public static final int getUShort(byte[] data,
                                  int pos)

Returns the 2-byte unsigned value at msg[pos]. The high order byte comes first. This has a range of 0 - Short.MAX_VALUE.

getUShortChar

public static final char getUShortChar(byte[] data,
                                       int pos)

Returns the 2-byte unsigned char at the pos. This reads from 0 - Short.MAX_VALUE * 2.

setUShort

public static final void setUShort(byte[] data,
                                   int pos,
                                   int value)

Set the 2-byte unsigned short at the position.

setUShortChar

public static final void setUShortChar(byte[] data,
                                       int pos,
                                       char value)

Set the 2-byte unsigned short at the position.

getUInt

public static final int getUInt(byte pValue)

Returns an unsigned int for the byte passed.

Parameters:

pValue - The byte.

Returns:

The unsigned int.

createIntB

public static final byte[] createIntB(int value)

Returns a new byte array (big endian) with the value.

Parameters:

value - The int to convert.

createInt

public static final byte[] createInt(int value)

Returns a new byte array with the passed value.

createUInt

public static final byte[] createUInt(long value)

Returns a new byte array with the passed value.

getUByte

public static final int getUByte(byte[] data,
                                 int pos)

Returns the 1-byte unsigned value at msg[pos].

setUInt

public static final void setUInt(byte[] data,
                                 int pos,
                                 long value)

Set the 4-byte unsigned short at the position.

getInt

public static final int getInt(byte[] data,
                               int pos)

Returns the 4-byte signed value at msg[pos]. The high order byte comes first.

setIntB

public static void setIntB(byte[] data,
                           int pos,
                           int value)

Set a int value in a byte array (big endian).

Parameters:

data - The value.

pos - The position.

value - The value.

getUInt

public static final long getUInt(byte[] data,
                                 int pos)

Returns the 4-byte unsigned value at msg[pos]. The high order byte comes first.

setLongL

public static final void setLongL(byte[] data,
                                  int pos,
                                  long value)

Set the 8-byte long (little endian).

getLongL

public static final long getLongL(byte[] data,
                                  int pos)

Returns the eight byte long (little endian). This came from: java.nio.Bits.

Parameters:

data - The place to read from.

pos - The position in the data.

Returns:

The little endian long.
