Method Detail

registerEntity

protected void registerEntity(Entity entity)

Description copied from class: AbstractEntityRegistrationManager

Registers in the report's JasperDesign instance whatever is needed to show a given entity.

Specified by:

transformEntity

protected Object transformEntity(Entity entity)
                          throws net.sf.jasperreports.engine.JRException

Description copied from class: AbstractEntityRegistrationManager

Transforms a DynamicJasper entity into a JasperReport one (JRDesignField, JRDesignParameter, JRDesignVariable)

Specified by:

transformEntity in class AbstractEntityRegistrationManager

Throws:

net.sf.jasperreports.engine.JRException

useVariableForCustomExpression

protected void useVariableForCustomExpression(net.sf.jasperreports.engine.design.JRDesignGroup group,
                                              net.sf.jasperreports.engine.design.JRDesignExpression jrExpression,
                                              CustomExpression customExpression)
                                       throws net.sf.jasperreports.engine.JRException

When a group expression gets its value from a CustomExpression, a variable must be used otherwise it will fail to work as expected.

Instead of using: GROUP -> CUSTOM_EXPRESSION

we use: GROUP -> VARIABLE -> CUSTOM_EXPRESSION

Parameters:

group -

jrExpression -

customExpression -

Throws:
