public static net.sf.jasperreports.engine.design.JRDesignExpression createExpression(net.sf.jasperreports.engine.design.JasperDesign jasperDesign,
                                                                                     SubreportParameter sp)

createAndRegisterExpression

public static net.sf.jasperreports.engine.design.JRDesignExpression createAndRegisterExpression(DynamicJasperDesign design,
                                                                                                String name,

createExpression

@Deprecated
public static net.sf.jasperreports.engine.design.JRDesignExpression createExpression(String name,
                                                                                                 CustomExpression expression)

Deprecated.

Use createAndRegisterExpression(DynamicJasperDesign, String, CustomExpression) This deprecated version may cause wrong field values when expression is executed in a group footer

Parameters:

name -

expression -

Returns:

createExpression

public static net.sf.jasperreports.engine.design.JRDesignExpression createExpression(String name,
                                                                                     CustomExpression expression,

Parameters:

name -

expression -

usePreviousFieldValues - if true, the Map with field values passed to the CustomExpresion contains the previous field value. This is needed when in group footer bands were at the time of executing the CustomExpression the fields values already corresponds to the next group value.

Returns:

getFieldsMapExpression

public static String getFieldsMapExpression(Collection columnsAndFields)

Returns:

getVariablesMapExpression

public static String getVariablesMapExpression(Collection variables)

Collection of JRVariable

Parameters:

variables -

Returns:

getParametersMapExpression

public static String getParametersMapExpression()

public static String createParameterName(String preffix,
                                         Object obj)

createCustomExpressionInvocationText

public static String createCustomExpressionInvocationText(CustomExpression customExpression,
