Package org.apache.log4j.rule
Class InequalityRule
java.lang.Object
org.apache.log4j.rule.AbstractRule
org.apache.log4j.rule.InequalityRule
- All Implemented Interfaces:
Serializable
,Rule
A Rule class implementing inequality evaluation.
expects to be able to convert two values to longs.
If a specific inequality evaluation class has been provided
for the event field, the appropriate rule is returned.
(For example, if the expression is Level < DEBUG,
a LevelInequalityRule is returned).

evaluate
Returns true if this implementation of the rule accepts the LoggingEvent, or false if not.What True/False means can be client-specific.
- Parameters:
event
- LoggingEvent this instance will evaluatematches
- a Map of event field keys to Sets of matching strings (may be null) which will be updated during execution of this method to include field and string matches based on the rule evaluation results- Returns:
- true if this Rule instance accepts the event, otherwise false.
