Method Details

customInitialize

protected void customInitialize()

Description copied from class: JRFillElementDataset

Initializes the element dataset.

The dataset is initialized before being used and after each time the dataset gets reset.

Specified by:

customInitialize in class JRFillElementDataset

See Also:

• JRFillElementDataset.getDatasetResetType()

createService

protected MultiAxisDataService createService(byte evaluation)
                                      throws JRException

Throws:

JRException

customEvaluate

protected void customEvaluate(JRCalculator calculator)
                       throws JRExpressionEvalException

Description copied from class: JRFillElementDataset

Evaluates 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:

customEvaluate in class JRFillElementDataset

Parameters:

calculator - used to evaluate expressions

Throws:

JRExpressionEvalException - any exception that occurs while evaluating expressions

customIncrement

protected void customIncrement()

Description copied from class: JRFillElementDataset

Increments the dataset by collecting the result of the expression evaluation.

Specified by:

customIncrement in class JRFillElementDataset

evaluateData

public void evaluateData(byte evaluationType)
                  throws JRException

Throws:

JRException

getDataSource

public MultiAxisDataSource getDataSource()
                                  throws JRException

Throws:

JRException

collectExpressions

public void collectExpressions(JRExpressionCollector collector)
