Class org.apache.cayenne.access.DataContext

Examples of org.apache.cayenne.access.DataContext.performQuery()

org.apache.cayenne.access.DataContext.performQuery()
Performs a single selecting query. Various query setting control the behavior of this method and the results returned:
- Query caching policy defines whether the results are retrieved from cache or fetched from the database. Note that queries that use caching must have a name that is used as a caching key.
- Query refreshing policy controls whether to refresh existing data objects and ignore any cached values.
- Query data rows policy defines whether the result should be returned as DataObjects or DataRows.
Since 1.2 takes any Query parameter, not just GenericSelectQuery
@return A list of DataObjects or a DataRows, depending on the value returned by{@link QueryMetadata#isFetchingDataRows()}.
