Method Detail

encode

public boolean encode(ClientEncoder clientEncoder,
                      Writer writer,
                      ActiveDataUpdateEvent event)
               throws IOException

Encode active data contents for the given ActiveDataEvent. The encoded contents is written to the writer. Encoder could optionally choose not to encode active data because of the high volum of change data. If active data is not encoded, active data channel will notify the component to refresh to get lastest data.

Overrides:

encode in class ActiveDataEncoder
