Constructor Detail

MetamodelImpl

public MetamodelImpl(MetaDataRepository repos)

Constructs a model with the current content of the supplied non-null repository.

Method Detail

getRepository

public MetaDataRepository getRepository()

embeddable

public <X> javax.persistence.metamodel.EmbeddableType<X> embeddable(Class<X> clazz)

Return the metamodel embeddable type representing the embeddable class.

Specified by:

embeddable in interface javax.persistence.metamodel.Metamodel

Parameters:

cls - the type of the represented embeddable class

Returns:

the metamodel embeddable type

Throws:

IllegalArgumentException - if not an embeddable class

entity

public <X> javax.persistence.metamodel.EntityType<X> entity(Class<X> clazz)

Return the metamodel entity type representing the entity.

Specified by:

entity in interface javax.persistence.metamodel.Metamodel

Parameters:

cls - the type of the represented entity

Returns:

the metamodel entity type

Throws:

IllegalArgumentException - if not an entity

getEmbeddables

public Set<javax.persistence.metamodel.EmbeddableType<?>> getEmbeddables()

Return the metamodel embeddable types.

Specified by:

getEmbeddables in interface javax.persistence.metamodel.Metamodel

Returns:

the metamodel embeddable types

getEntities

public Set<javax.persistence.metamodel.EntityType<?>> getEntities()

Return the metamodel entity types.

Specified by:

getEntities in interface javax.persistence.metamodel.Metamodel

Returns:

the metamodel entity types

getManagedTypes

public Set<javax.persistence.metamodel.ManagedType<?>> getManagedTypes()

Return the metamodel managed types.

Specified by:

getManagedTypes in interface javax.persistence.metamodel.Metamodel

Returns:

the metamodel managed types

managedType

public <X> javax.persistence.metamodel.ManagedType<X> managedType(Class<X> clazz)

Return the metamodel managed type representing the entity, mapped superclass, or embeddable class.

Specified by:

managedType in interface javax.persistence.metamodel.Metamodel

Parameters:

cls - the type of the represented managed class

Returns:

the metamodel managed type

Throws:

IllegalArgumentException - if not a managed class

getType

public <X> javax.persistence.metamodel.Type<X> getType(Class<X> cls)

Return the type representing the basic, entity, mapped superclass, or embeddable class. This method differs from #type(Class) as it also creates a basic or pesudo type for the given class argument if not already available in this receiver.

Parameters:

cls - the type of the represented managed class

Returns:

the metamodel managed type

Throws:

IllegalArgumentException - if not a managed class

getPersistenceType

public static javax.persistence.metamodel.Type.PersistenceType getPersistenceType(ClassMetaData meta)

unmodifiableSet

public <T> Set<T> unmodifiableSet(Collection<T> coll)

populate

public <X> void populate(AbstractManagedType<X> type)

Populate the static fields of the canonical type.

classForName

                          String[] imports)

Specified by:

classForName in interface Resolver

getFilterListener

public FilterListener getFilterListener(String tag)

Specified by:

getFilterListener in interface Resolver

getQueryContext

public QueryContext getQueryContext()

Specified by:

getQueryContext in interface Resolver
