customEvaluate
Description copied from class:JRFillElementDatasetEvaluates the expressions associated with the dataset.Usually, the result of the evaluation would be preserved so that it is used in
JRFillElementDataset.customIncrement()- Specified by:
customEvaluatein classJRFillElementDataset- Parameters:
calculator- used to evaluate expressions- Throws:
JRExpressionEvalException- any exception that occurs while evaluating expressions
-
customIncrement
protected void customIncrement()Description copied from class:JRFillElementDatasetIncrements the dataset by collecting the result of the expression evaluation.- Specified by:
customIncrementin classJRFillElementDataset
-
customInitialize
protected void customInitialize()Description copied from class:JRFillElementDatasetInitializes the element dataset.The dataset is initialized before being used and after each time the dataset gets reset.
