TotalGroupSumQuotientPercentFunction
public class TotalGroupSumQuotientPercentFunction extends TotalGroupSumQuotientFunction (Code)
A report function that calculates the quotient of two summed fields (columns) from the data-row. This function produces a global total. The total sum of the group is known when the group processing starts and the report is not performing a prepare-run. The sum is calculated in the prepare run and recalled in the printing run.

The function can be used in two ways:

  • to calculate a quotient for the entire report;
  • to calculate a quotient within a particular group;
This function expects its input values to be either java.lang.Number instances or Strings that can be parsed to java.lang.Number instances using a java.text.DecimalFormat.

The function undestands three parameters. The dividend parameter is required and denotes the name of an ItemBand-field which gets summed up as dividend. The divisor parameter is required and denotes the name of an ItemBand-field which gets summed up as divisor.

The parameter group denotes the name of a group. When this group is started, the counter gets reseted to null. This parameter is optional.

This function scales the computed percentage to 100. A value of 100% will therefore be returned as 100 instead of 1. The result of this function cannot be used together with the percentage operator of the NumberFormat in a Number-field.
