Method Detail

bytesToInt

public static final int bytesToInt(byte[] array,
                                   int offset)

Unmarshal a byte array to an integer. Assume the bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+3] is the least-significant-byte.

Parameters:

array - The array of bytes.

offset - The offset from which to start unmarshalling.

intToBytes

public static final byte[] intToBytes(int value)

Marshal an integer to a byte array. The bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+3] is the least-significant-byte.

intToBytes

public static final void intToBytes(int value,
                                    byte[] array,
                                    int offset)

longToBytes

public static final byte[] longToBytes(long value)

Unmarshal a byte array to an long. Assume the bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+7] is the least-significant-byte.

bytesToLong

public static final long bytesToLong(byte[] array,
                                     int offset)

longToBytes

public static final void longToBytes(long value,
                                     byte[] array,
                                     int offset)

Marshal an long to a byte array. The bytes are in BIGENDIAN order. i.e. array[offset] is the most-significant-byte and array[offset+7] is the least-significant-byte.

Parameters:

array - The array of bytes.

offset - The offset from which to start marshalling.
