Integrating SPLASH into CCL

CCL uses Flex operators to execute SPLASH code to process events. They have local declaration blocks, which are blocks of SPLASH function and variable declarations. They also have one method block per input stream and an optional timer block also written in SPLASH.

• Access to the Event
  When an event arrives at a Flex operator from an input stream, the method for that input stream is run.
• Access to Input Streams
  Within method and timer code in Flex operators, you can examine records in any of the input streams.
• Output Statement
  Typically, a Flex operator method creates one or more events in response to an event. In order to use these events to affect the store of records, and to send downstream to other streams, use the output statement.
• Notes on Transactions
  A Flex operator method processes one event at a time. The Event Stream Processor can, however, be fed data in transaction blocks (groups of insert, update, and delete events).
