final public static String	PARAMETER_HIBERNATE_SESSION Built-in parameter holding the value of the Hibernate session to be used for creating the query.
final public static String	PROPERTY_HIBERNATE_CLEAR_CACHE Property specifying whether hibernate session cache should be cleared between two consecutive fetches when using pagination.
final public static String	PROPERTY_HIBERNATE_FIELD_MAPPING_DESCRIPTIONS Property specifying whether field descriptions should be used to determine the mapping between the fields and the query return values.
final public static String	PROPERTY_HIBERNATE_QUERY_LIST_PAGE_SIZE Property specifying the number of result rows to be retrieved at once when the execution type is list.
final public static String	PROPERTY_HIBERNATE_QUERY_RUN_TYPE Property specifying the query execution type.
final public static String	QUERY_LANGUAGE_HQL HQL query language.
final public static String	VALUE_HIBERNATE_QUERY_RUN_TYPE_ITERATE Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to iterate execution type.
final public static String	VALUE_HIBERNATE_QUERY_RUN_TYPE_LIST Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to list execution type.
final public static String	VALUE_HIBERNATE_QUERY_RUN_TYPE_SCROLL Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to scroll execution type.

Method Summary
public JRQueryExecuter	createQueryExecuter(JRDataset dataset, Map parameters)
public Object[]	getBuiltinParameters() Returns an array containing the JRHibernateQueryExecuterFactory.PARAMETER_HIBERNATE_SESSION PARAMETER_HIBERNATE_SESSION and JRHibernateQueryExecuterFactory.PARAMETER_HIBERNATE_FILTER_COLLECTION PARAMETER_HIBERNATE_FILTER_COLLECTION paramters.
public boolean	supportsQueryParameterType(String className) Returns `true` for all parameter types.

Field Detail

PARAMETER_HIBERNATE_FILTER_COLLECTION
final public static String PARAMETER_HIBERNATE_FILTER_COLLECTION(Code)
	Built-in parameter used for collection filter queries. The value of this paramter will be used as the collection to filter using the query.

PARAMETER_HIBERNATE_SESSION
final public static String PARAMETER_HIBERNATE_SESSION(Code)
	Built-in parameter holding the value of the Hibernate session to be used for creating the query.

PROPERTY_HIBERNATE_CLEAR_CACHE

final public static String PROPERTY_HIBERNATE_CLEAR_CACHE(Code)

Property specifying whether hibernate session cache should be cleared between two consecutive fetches when using pagination.

By default, the cache cleanup is not performed.

PROPERTY_HIBERNATE_FIELD_MAPPING_DESCRIPTIONS
final public static String PROPERTY_HIBERNATE_FIELD_MAPPING_DESCRIPTIONS(Code)
	Property specifying whether field descriptions should be used to determine the mapping between the fields and the query return values.

PROPERTY_HIBERNATE_QUERY_LIST_PAGE_SIZE

final public static String PROPERTY_HIBERNATE_QUERY_LIST_PAGE_SIZE(Code)

Property specifying the number of result rows to be retrieved at once when the execution type is list.

Result pagination is implemented by org.hibernate.Query.setFirstResult() and org.hibernate.Query.setMaxResults().

By default, all the rows are retrieved (no result pagination is performed).

PROPERTY_HIBERNATE_QUERY_RUN_TYPE

final public static String PROPERTY_HIBERNATE_QUERY_RUN_TYPE(Code)

Property specifying the query execution type.

Possible values are:

list (default) - the query will be run by calling org.hibernate.Query.list()
iterate - the query will be run by calling org.hibernate.Query.iterate()
scroll - the query will be run by calling org.hibernate.Query.scroll()

QUERY_LANGUAGE_HQL
final public static String QUERY_LANGUAGE_HQL(Code)
	HQL query language.

VALUE_HIBERNATE_QUERY_RUN_TYPE_ITERATE
final public static String VALUE_HIBERNATE_QUERY_RUN_TYPE_ITERATE(Code)
	Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to iterate execution type.

VALUE_HIBERNATE_QUERY_RUN_TYPE_LIST
final public static String VALUE_HIBERNATE_QUERY_RUN_TYPE_LIST(Code)
	Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to list execution type.

VALUE_HIBERNATE_QUERY_RUN_TYPE_SCROLL
final public static String VALUE_HIBERNATE_QUERY_RUN_TYPE_SCROLL(Code)
	Value of the JRHibernateQueryExecuterFactory.PROPERTY_HIBERNATE_QUERY_RUN_TYPE PROPERTY_HIBERNATE_QUERY_RUN_TYPE property corresponding to scroll execution type.

Method Detail

public JRQueryExecuter createQueryExecuter(JRDataset dataset, Map parameters) throws JRException(Code)

getBuiltinParameters
public Object[] getBuiltinParameters()(Code)
	Returns an array containing the JRHibernateQueryExecuterFactory.PARAMETER_HIBERNATE_SESSION PARAMETER_HIBERNATE_SESSION and JRHibernateQueryExecuterFactory.PARAMETER_HIBERNATE_FILTER_COLLECTION PARAMETER_HIBERNATE_FILTER_COLLECTION paramters.

supportsQueryParameterType
public boolean supportsQueryParameterType(String className)(Code)
