Method Detail

compileReport

JasperReport compileReport(JasperDesign jasperDesign)
                           throws JRException

Compiles a report design.

The compilation consists of verification of the design, generation of expression evaluators and construction of a serializable read-only version of the report.

A report compiler should usually extend JRAbstractCompiler.

Parameters:

jasperDesign - the report design

Returns:

the compiled report

Throws:

JRException

loadEvaluator

JREvaluator loadEvaluator(JasperReport jasperReport)
                          throws JRException

Loads the evaluator for a report's main dataset.

Parameters:

jasperReport - the report

Returns:

the evaluator for the report's main dataset

Throws:

JRException

loadEvaluator

JREvaluator loadEvaluator(JasperReport jasperReport,
                          JRDataset dataset)
                          throws JRException

Loads a expression evaluator class for a dataset of a report.

Parameters:

jasperReport - the report

dataset - the dataset

Returns:

an instance of the dataset evaluator class

Throws:

JRException

loadEvaluator

JREvaluator loadEvaluator(JasperReport jasperReport,
                          JRCrosstab crosstab)
                          throws JRException

Loads a expression evaluator class for a crosstab of a report.

Parameters:

jasperReport - the report

crosstab - the crosstab

Returns:

an instance of the dataset evaluator class

Throws:

JRException
