Method Detail

getBuiltinParameters

public Object[] getBuiltinParameters()

Description copied from interface: QueryExecuterFactory

Returns the built-in parameters associated with this query type.

These parameters will be created as system-defined parameters for each report/dataset having a query of this type.

The returned array should contain consecutive pairs of parameter names and parameter classes (e.g. {"Param1", String.class, "Param2", "List.class"}).

Returns:

array of built-in parameter names and types associated with this query type

createQueryExecuter

public JRQueryExecuter createQueryExecuter(JasperReportsContext jasperReportsContext,
                                  JRDataset dataset,
                                  Map<String,? extends JRValueParameter> parameters)
                                    throws JRException

Description copied from interface: QueryExecuterFactory

Creates a query executer.

Parameters:

jasperReportsContext - the JasperReportsContext

dataset - the dataset containing the query, fields, etc

parameters - map of value parameters (instances of JRValueParameter) indexed by name

Returns:

a query executer

Throws:

JRException

supportsQueryParameterType

Description copied from interface: QueryExecuterFactory

Decides whether the query executers created by this factory support a query parameter type.

This check is performed for all $P{..} parameters in the query.

Parameters:

className - the value class name of the parameter

Returns:

whether the parameter value type is supported
