Examples of org.apache.isis.runtimes.dflt.runtime.persistence.query.PersistenceQueryBuiltIn.matches()

org.apache.isis.runtimes.dflt.runtime.persistence.query.PersistenceQueryBuiltIn.matches()
The built-in queries iterate over all instances.
This is similar to the {@link Filter} interface in the applib, except thefiltering is done within the object store as opposed to be the {@link DomainObjectContainer}.
Object store implementations do not necessarily need to rely on this method. For example, an RDBMS-based implementation may use an alternative mechanism to determine the matching results, for example using a WHERE clause in some SQL query.
