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.
es.source provides the translation from events to streams
triggers cause events to be scheduled in es.source and es.sink block event queues.
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
