Class NotInReporterListFunction

java.lang.Object
net.sf.basedb.util.jep.NotInReporterListFunction
All Implemented Interfaces:
JepFunction, JepRestrictionFunction, org.nfunk.jep.function.PostfixMathCommandI
public class NotInReporterListFunction extends Object implements JepRestrictionFunction
A JEP function class that adds a notInList(reporterListId) function to a JEP expression parser. The function will check if a reporter doesn't exists in the reporter list with the ID given as an argument to this function.

To be able to use this function it must be registered with the JEP parser and, before the expression is evaluated, a SqlResult object must be set.
