decodeBinary

public final void decodeBinary(LLRPBitList binary)

decodeBinary should be called from Constructor Taking binary encoded parameter as argument

Specified by:

decodeBinary in class LLRPParameter

Parameters:

binary - list to be decoded

Throws:

java.lang.IllegalArgumentException - in case of any error or unexpected behaviour

encodeBinary

public final LLRPBitList encodeBinary()

create binary encoding of this parameter. Returns a LLRPBitList which can concatenated with binary encoding of other parameters to form a binary encoded messages

Specified by:

encodeBinary in class LLRPParameter

Returns:

LLRPBitList

decodeBinarySpecific

protected abstract void decodeBinarySpecific(LLRPBitList binary)

decoding function to be implemented by each parameter

Parameters:

binary - binary representation of the parameter

encodeBinarySpecific

protected abstract LLRPBitList encodeBinarySpecific()

protected method to force subclasses to implement their specific encoding

Returns:

LLRPBitList
