public interface JRQueryExecuterFactory

Factory classes used to create query executers.

For each query language, a query executer factory must be created and registered as a JR property.

Query executer factory instances must be thread-safe as they are cached and used as singletons.

Field Detail

QUERY_EXECUTER_FACTORY_PREFIX

static final String QUERY_EXECUTER_FACTORY_PREFIX

Deprecated. Replaced by QueryExecuterFactory.QUERY_EXECUTER_FACTORY_PREFIX.

Prefix for query executer factory properties.

To obtain query executer factories, a property having the query language appended to this prefix is used to get the query executer factory name.

Method Detail

getBuiltinParameters

Object[] getBuiltinParameters()

Deprecated.

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

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

Deprecated. Replaced by QueryExecuterFactory.createQueryExecuter(net.sf.jasperreports.engine.JasperReportsContext, JRDataset, Map).

Creates a query executer.

This method is called at fill time for reports/datasets having a query supported by this factory.

Parameters:

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

boolean supportsQueryParameterType(String className)

Deprecated.

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
