Avaya DXX-1015-01 manual Relational Operators, Symbol Definition Description

Setting Event Monitoring Criteria

This assign criteria watches all EDUs in the system because all EDU IDs are longer than empty strings.

Change events that do not reflect a change in the loginid, any matching data.*, or any

￿subcontainer of the call container are also suppressed.

Change events that not suppressed are trimmed to list only the names that are provided on the projection list. The duid, time, and modifier fields are also provided.

Note: Watch and drop events are not modified and they are always sent with their full content. User events, which are very rare, would be modified as they are actually change events with a different name.

Relational Operators

Values can be compared to each other as described below. There are four permissible relational operators. In the description column, the term couple refers to a name/value pair.

Symbol	Definition	Description
=	equal	Find a couple that matches the specified name and value.
		Wildcards are accepted.
<	less than	For a given name, find all couples with values less than the
		specified search value (string-based).
>	greater than	For a given name, find the set of couples with values
		greater than the specified criteria (string-based).
:	exactly equal to	For a given name, find a couple that exactly matches the
		specified value. Wildcards are not accepted.
#	not	Expressions are not equal to each other.

The ADU Server compares the name/value data within an ADU against the criteria string one character at a time, starting with the leftmost character, until either a mismatch occurs or one field runs out of characters. Comparisons are case-sensitive. “Foo” is not the same as “foo” or “FOO”. To avoid ambiguity, enclose the specified value within double quotes (“”). Within a quoted string, (\") means quote and (\\) means backslash.

If the strings match character for character, they are equal. Strings can also be relatively compared. If one field runs out of characters without a mismatch, the relatively longer field is greater (for example, abc < abcd). If a mismatch occurs, the field containing the greater character is greater, (for example, 111 < 119). Because the comparison is string-based, not numeric, the field with the greater initial character is greater, (for example, 2 > 119).

Wildcards are permitted only with the equal (=) operator.
