Module Info

These blocks are intended to help improve the translation of streams of data items into scheduled-finite length events occurring in the data streams in both directions.

Some examples of specific triggers included are,

- es_trigger_edge_f: cause an event when float stream rises
                     above a fixed threshold value
- es_trigger_sample_timer: cause an event to occur on
                a periodic sample increment in the stream

Some example of specific handlers included are,

- es_handler_print: print the event to STDOUT
- es_handler_pdu: convert the event to a PDU and send
                    it out a message port
- es_handler_insert_vector: a source handler which
            populates an event window from a PMT vector
- es_handler_file: a sink handler which writes event
            contents out to a file
