| JRQueryExecuterFactory | | public interface JRQueryExecuterFactory (Code) | | 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.

| Method Summary | |
| public JRQueryExecuter | createQueryExecuter(JRDataset dataset, Map parameters)
Creates a query executer. | | public Object[] | getBuiltinParameters()
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. | | public boolean | supportsQueryParameterType(String className)
Decides whether the query executers created by this factory support a query parameter type. |
| QUERY_EXECUTER_FACTORY_PREFIX | | final public static String QUERY_EXECUTER_FACTORY_PREFIX(Code) | | 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.
|
| createQueryExecuter | | public JRQueryExecuter createQueryExecuter(JRDataset dataset, Map parameters) throws JRException(Code) | | 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:
parameters - map of value parameters (instances of JRValueParameter JRValueParameter)indexed by name a query executer
throws:
JRException - |
| getBuiltinParameters | | public Object[] getBuiltinParameters()(Code) | | 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"}).
array of built-in parameter names and types associated with this query type |
| supportsQueryParameterType | | public boolean supportsQueryParameterType(String className)(Code) | | 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 whether the parameter value type is supported |
