Field Summary |
|
final public static byte | CALCULATION_AVERAGE The value is obtained by calculating the average for the series of values obtained by evaluating the variable's
expression for each record in the data source. |
final public static byte | CALCULATION_COUNT The value is calculated by counting the non-null values of the variable expression with every iteration in the data source. |
final public static byte | CALCULATION_DISTINCT_COUNT The value is calculated by counting the distinct non-null values of the variable expression with every iteration in the data source. |
final public static byte | CALCULATION_FIRST The variable keeps the first value and does not increment it on subsequent iterations. |
final public static byte | CALCULATION_HIGHEST The value of the variable represents the highest in the series of values obtained by evaluating the variable's
expression for each data source record. |
final public static byte | CALCULATION_LOWEST The value of the variable represents the lowest in the series of values obtained by evaluating the variable's
expression for each data source record. |
final public static byte | CALCULATION_NOTHING The value is calculated by simply evaluating the variable expression. |
final public static byte | CALCULATION_STANDARD_DEVIATION The value is obtained by calculating the standard deviation for the series of values returned by evaluating the
variable's expression.
Just like for the variables that calculate the average, the engine creates and uses helper report variables
for first obtaining the sum and the count that correspond to your current series of values. |
final public static byte | CALCULATION_SUM The value is calculated by summing up the values returned by the variable's expression. |
final public static byte | CALCULATION_SYSTEM The value is not calculated by JasperReports. |
final public static byte | CALCULATION_VARIANCE The value is obtained by calculating the variance for the series of values returned by evaluating the
variable's expression. |
final public static String | COLUMN_COUNT This variable contains the number of records that were processed when generating the current column. |
final public static String | COLUMN_NUMBER Built-in variable containing the current column number. |
final public static String | PAGE_COUNT Built-in variable containing the number of records that were processed when generating the current page. |
final public static String | PAGE_NUMBER Built-in variable containing the current page number. |
final public static String | REPORT_COUNT Built-in variable that contains the total number of records read from the datasource. |
final public static byte | RESET_TYPE_COLUMN The variable is reinitialized at the beginning of each new column. |
final public static byte | RESET_TYPE_GROUP The variable is reinitialized every time the group specified by the
JRVariable.getResetGroup method breaks. |
final public static byte | RESET_TYPE_NONE The variable will never be initialized using its initial value expression and will only contain values obtained by
evaluating the variable's expression. |
final public static byte | RESET_TYPE_PAGE The variable is reinitialized at the beginning of each new page. |
final public static byte | RESET_TYPE_REPORT The variable is initialized only once, at the beginning of the report filling process, with the value returned by
the variable's initial value expression. |
