Class JRExpressionCollector

java.lang.Object
  net.sf.jasperreports.engine.JRExpressionCollector

public class JRExpressionCollector
extends java.lang.Object

An expression collector traverses a report and collects report expressions out of it.

The expressions are then included into evaluator classes which are compiled and used at report fill time to evaluate expressions.
