Field Detail

COMPILER_PREFIX

static final java.lang.String COMPILER_PREFIX

Prefix for properties that map report compilers to expression languages.

Properties having this prefix are used to indicate the JRCompiler implementation to be used when compiling report designs that rely on the expression language specified as propety suffix.

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
