getBuiltinParameters
public java.lang.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, java.util.Map<java.lang.String,? extends JRValueParameter> parameters) throws JRException
Description copied from interface:QueryExecuterFactory
Creates a query executer. This method is called at fill time for reports/datasets having a query supported by this factory.- Parameters:
jasperReportsContext
- the JasperReportsContextdataset
- the dataset containing the query, fields, etcparameters
- map of value parameters (instances ofJRValueParameter
) indexed by name- Returns:
- a query executer
- Throws:
JRException

supportsQueryParameterType
public boolean supportsQueryParameterType(java.lang.String className)
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
