Class NotInReporterListFunction

java.lang.Object
  extended by 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.

Constructor Detail

NotInReporterListFunction

public NotInReporterListFunction(DbControl dc)
Create a new instance of this function. The new instance cannot be used to dynamically evaluate expressions. It should only be used for converting JEP formulas to Restriction:s.

Parameters:
dc - Open DbControl to use when accessing database and checking permissions.
