This function can be used to convert simple running-functions into total-functions by wrapping them up. The wrapped up function will be evaluated as usual and the result at the end of the report and/or end of the group will be stored in the TotalCalculationFunction. author:    Thomas Morgner Constructor Summary public   TotalCalculationFunction()      Constructs a new function. Method Summary public  String getField()      Returns the field used by the function. public  String getGroup()      Returns the name of the group to be totalled. public  Expression getInstance()      public  Object getValue()      Return the current expression value. public  void groupFinished(ReportEvent event)      Receives notification that a group has finished. public  void groupStarted(ReportEvent event)      Receives notification that a group has started. public  void reportFinished(ReportEvent event)      Receives notification that the report has finished. public  void reportInitialized(ReportEvent event)      Receives notification that the report has started. public  void setField(String field)      Sets the field name for the function. public  void setGroup(String group)      Defines the name of the group to be totalled. Constructor Detail TotalCalculationFunction public TotalCalculationFunction()(Code) Constructs a new function. Initially the function has no name...be sure to assign one before using the function. Method Detail getField public String getField()(Code) Returns the field used by the function. The field name corresponds to a column name in the report's data-row. The field name. getGroup public String getGroup()(Code) Returns the name of the group to be totalled. the group name. getInstance public Expression getInstance()(Code) getValue public Object getValue()(Code) Return the current expression value. The value depends (obviously) on the expression implementation. the value of the function. groupFinished public void groupFinished(ReportEvent event)(Code) Receives notification that a group has finished. Parameters:   event - the event. groupStarted public void groupStarted(ReportEvent event)(Code) Receives notification that a group has started. Parameters:   event - the event. reportFinished public void reportFinished(ReportEvent event)(Code) Receives notification that the report has finished. Parameters:   event - the event. reportInitialized public void reportInitialized(ReportEvent event)(Code) Receives notification that the report has started. Parameters:   event - the event. setField public void setField(String field)(Code) Sets the field name for the function. The field name corresponds to a column name in the report's data-row. Parameters:   field - the field name. setGroup public void setGroup(String group)(Code) Defines the name of the group to be totalled. If the name is null, all groups are totalled. Parameters:   group - the group name.
