Advanced CCL Programming Techniques

Use advanced CCL techniques to develop sophisticated and complex projects.

Use declare blocks to define variables, constants, SPLASH functions, and custom datatypes.

Create modules to encapsulate reusable code.

Use explicit memory stores to fine tune performance. Use log stores to retain the contents of named windows on disk, to allow for recovery in the event of a failure.

• Declare Blocks
  Declare blocks allow a model designer to include elements of functional programming, such as variables, parameters, typedefs, and function definitions in CCL data models.
• Flex Operators
  Flex operators provide extensibility to CCL, allowing custom event handlers, written in SPLASH, to produce derived streams or windows.
• Modularity
  A module in Sybase Event Stream Processor offers reusability; it can be loaded and used multiple times in a single project or in many projects.
• Data Recovery
  A log store allows data recovery inside a window if a server fails or is shut down.
• Error Streams
  Error streams gather errors and the records that caused them.
