org.jfree.report.function.DateCutExpression
| DateCutExpression | | public class DateCutExpression extends AbstractExpression (Code) | | Prunes a date in a calendar-unware way. This method can be used to zero the milli-seconds or seconds and so on from a
date-object. For more complex operations, the
org.jfree.report.function.date.VariableDateExpression should be
used instead.
This expression simply executes a integer division followed by a integer multiplication on the milliseconds since
01-01-1970. For a factor of 1000, this sets the milliseconds to zero.
