Class InequalityRule

java.lang.Object
org.apache.log4j.rule.AbstractRule
org.apache.log4j.rule.InequalityRule
All Implemented Interfaces:
Serializable, Rule

public class InequalityRule extends AbstractRule
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 &lt DEBUG, a LevelInequalityRule is returned).

    • getRule

      public static Rule getRule(String inequalitySymbol, Stack stack)
      Create new instance from top two elements on stack.
      Parameters:
      inequalitySymbol - inequality symbol.
      stack - stack.
      Returns:
      rule.
    • getRule

      public static Rule getRule(String inequalitySymbol, String field, String value)
      Create new instance from top two elements on stack.
      Parameters:
      inequalitySymbol - inequality symbol.
      field - field.
      value - comparison value.

    • evaluate

      public boolean evaluate(org.apache.log4j.spi.LoggingEvent event, Map matches)
      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 evaluate
      matches - 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.
