publish

public final void publish(Name interestName,
                          Name dataName,
                          Blob content,

                          IOException

Put all the segments in the memory store.

Parameters:

interestName - If the Interest name ends in a segment, immediately send the Data packet for the segment to the Face.

dataName - The Data name, which has components after the Interest name.

content - The content of the data to be segmented.

freshnessPeriod - The freshness period of the segments, in milliseconds.

signingInfo - The SigningInfo for signing segment Data packets.

Throws:

EncodingException

Parameters:

interestName - If the Interest name ends in a segment, immediately send the Data packet for the segment to the Face.

dataName - The Data name, which has components after the Interest name.

content - The content of the data to be segmented.

freshnessPeriod - The freshness period of the segments, in milliseconds.

IOException

replyFromStore

public final boolean replyFromStore(Name interestName)
                             throws IOException

Try to reply to the Interest name from the memory store.

Parameters:

interestName - The Interest name for looking up in the memory store.

Returns:

True if sent the segment Data packet to the Face, or false if we cannot find the segment, in which case the caller is expected to publish the segment.

Throws:

IOException
