AbstractEncodedDataObject

protected AbstractEncodedDataObject()

Constructs a new AbstractEncodedDataObject with uninitialised encoded state.

AbstractEncodedDataObject

protected AbstractEncodedDataObject(byte[] data,
                         int start,
                         int len)

Constructs a new AbstractEncodedDataObject from part of given network-encoded data. The part starts at index start and is len bytes long. The data is not decoded and might not be decodable.

Parameters:

data - network-encoded data

start - starting offset of network-encoded data

len - length of encoded data in bytes

Throws:

NullPointerException - if data is null

IllegalArgumentException - if len is negative

ArrayIndexOutOfBoundsException - if the part is not within the data
