public PersistenceUnitClassFinder()

Method Details

scanClasspath

public void scanClasspath(Configuration configuration)

Scans application classpath based on the JOPAPersistenceProperties.SCAN_PACKAGE, looking for classes relevant for the persistence provider.

These classes include:

• Entities, i.e. classes annotated with OWLClass,
• Result result mapping classes, i.e. classes annotated with SparqlResultSetMapping or SparqlResultSetMappings

Parameters:

configuration - Persistence configuration, should contain value for the JOPAPersistenceProperties.SCAN_PACKAGE property

Throws:

IllegalArgumentException - If JOPAPersistenceProperties.SCAN_PACKAGE values is missing

getEntities

public Set<Class<?>> getEntities()

Gets entity classes found during classpath scanning.

Returns:

Set of entity classes discovered on classpath

getResultSetMappings

public Set<SparqlResultSetMapping> getResultSetMappings()

Gets SparqlResultSetMappings found during classpath scanning.

Returns:

Set of result set mapping annotations discovered on classpath

getAttributeConverters

public Map<Class<?>,ConverterWrapper<?,?>> getAttributeConverters()

Gets AttributeConverter implementations found during classpath scanning.

The converters are wrapped in an internal helper class ConverterWrapper.

Returns:

Map of classes to custom converters
