Serialize an int value into an array of bytes.

Parameters:

value - the int value to serialize.

data - the array of bytes into which to serialize the value.

offset - the position in the array of byte at which the serializatrion should start.

Returns:

an array of bytes filled with the value's representation, starting at the specified offset.

writeInt

public static byte[] writeInt(int value,
                              byte[] data,
                              int offset)

Serialize an int value into an array of bytes.

Parameters:

value - the int value to serialize.

data - the array of bytes into which to serialize the value.

offset - the position in the array of byte at which the serializatrion should start.

Returns:

an array of bytes filled with the value's representation, starting at the specified offset.

writeLong

public static byte[] writeLong(long value,
                               byte[] data,
                               int offset)

Serialize a long value into an array of bytes.

Parameters:

value - the int value to serialize.

data - the array of bytes into which to serialize the value.

offset - the position in the array of byte at which the serializatrion should start.

Returns:

an array of bytes filled with the value's representation, starting at the specified offset.
