Conventions
The notation conventions used in each chapter of this document are as follows:
Chapter 1, "Complex Event Processing Language Reference" conventions
The following notation is used in the complex event processing language syntax:
Square brackets, "[" and "]", indicate that the part enclosed by the brackets is optional.
A vertical line, "|", indicates the need to make a selection from the items separated by the vertical line. If the boundary between the selection options and surrounding syntax is not clear, the list of selection options is enclosed in parentheses, "(" and ")".
Three periods, "..." indicates a continuation of the previous part in a similar way.
Variable information or content that can be modified is italicized and written in mixed case (for example: newBkpDir).
If square brackets or parentheses are used as part of sentence structure, they are underlined "[" "]" "(" ")" to distinguish them from the square brackets and parentheses used as notation conventions.
Chapter 2, "Filter Rule Language Reference" conventions
The symbols used in the filter rule language format have the following meanings:
Symbol | Explanation |
|---|---|
| The part branching below the line indicates elements that are optional. Example:
|
| The parts branching vertically in parallel indicate that one of these elements must be selected. Example:
|
| The arrow line pointing backwards over the top of the line indicates that the element is repeated. Example:
|
