Method Detail

decode

public int decode(byte[] data)

Decode the given bytearray to an integer value.

Parameters:

data - the bytearray

Returns:

the integer value

encode

public abstract byte[] encode(int value)

Encode the given value to a new bytearray

Parameters:

value - the value

Returns:

a new bytearray

encodeTo

public abstract void encodeTo(int value,
            byte[] toArray,
            int start)

Encode the given value to some location in an existing bytearray

Parameters:

value - the value

toArray - the array to populate

start - the start index to begin encoding at

decode

public abstract int decode(byte[] data,
         int start,
         int len)

Decode a value from some part of a bytearray

Parameters:

data - the bytearray

start - where to start decoding

len - how many bytes to decode

rangeCheck

public abstract void rangeCheck(int value)
                         throws EncodeException

Check if a given value is in the encodable range for this codec.

Parameters:

value - the value to check

Throws:

EncodeException - if value is out of range
