Class ElementReader

java.lang.Object

net.named_data.jndn.encoding.ElementReader

public class ElementReader
extends Object

A ElementReader lets you call onReceivedData multiple times which uses a TlvStructureDecoder to detect the end of an NDN-TLV element and calls elementListener.onReceivedElement(element) with the element. This handles the case where a single call to onReceivedData may contain multiple elements.

onReceivedData

public void onReceivedData(ByteBuffer data)
                    throws EncodingException

Continue to read data until the end of an element, then call elementListener.onReceivedElement(element ). The buffer passed to onReceivedElement is only valid during this call. If you need the data later, you must copy.

Parameters:

data - The input data containing bytes of the element to read. This reads from position() to limit(), but does not change the position.

Throws:

EncodingException - For invalid encoding.
