Method Details

getTypeConfiguration

TypeConfiguration getTypeConfiguration()

The TypeConfiguration this metamodel is associated with

resolveMappingExpressible

MappingModelExpressible<?> resolveMappingExpressible(SqmExpressible<?> sqmExpressible,
 Function<NavigablePath,TableGroup> tableGroupLocator)

resolveQueryParameterType

<T> BindableType<T> resolveQueryParameterType(Class<T> javaType)

Given a Java type, determine the corresponding BindableType to use implicitly

forEachEntityDescriptor

void forEachEntityDescriptor(Consumer<EntityPersister> action)

Visit all entity mapping descriptors defined in the model

streamEntityDescriptors

Stream<EntityPersister> streamEntityDescriptors()

getEntityDescriptor

EntityPersister getEntityDescriptor(String entityName)

Get an entity mapping descriptor based on its Hibernate entity-name

Throws:

IllegalArgumentException - if the name does not refer to an entity

See Also:

• findEntityDescriptor(java.lang.String)

getEntityDescriptor

EntityPersister getEntityDescriptor(NavigableRole name)

Get an entity mapping descriptor based on its NavigableRole.

Throws:

IllegalArgumentException - if the name does not refer to an entity

See Also:

• findEntityDescriptor(java.lang.String)

getEmbeddableValuedModelPart

EmbeddableValuedModelPart getEmbeddableValuedModelPart(NavigableRole role)

Get an EmbeddableMappingType based on its NavigableRole.

Throws:

IllegalArgumentException - if the role does not refer to an entity

See Also:

• findEntityDescriptor(java.lang.String)

getEntityDescriptor

EntityPersister getEntityDescriptor(Class<?> entityJavaType)

Get an entity mapping descriptor based on its Class.

Throws:

See Also:

• findEntityDescriptor(java.lang.String)

findEntityDescriptor

EntityPersister findEntityDescriptor(String entityName)

Find an entity mapping descriptor based on its Hibernate entity-name.

API Note:

Returns null rather than throwing exception

findEntityDescriptor

EntityPersister findEntityDescriptor(Class<?> entityJavaType)

Find an entity mapping descriptor based on its Class.

API Note:

Returns null rather than throwing exception

isEntityClass

boolean isEntityClass(Class<?> entityJavaType)

locateEntityDescriptor

EntityPersister locateEntityDescriptor(Class<?> byClass)

Locate an entity mapping descriptor by Class. The passed Class might refer to either the entity Class directly, or it might name a proxy interface for the entity. This method accounts for both, preferring the direct entity name.

Throws:

UnknownEntityTypeException - If a matching EntityPersister cannot be located

locateEntityPersister

@Deprecated(since="6.0")
default EntityPersister locateEntityPersister(Class<?> byClass)

Deprecated.

use locateEntityDescriptor(Class) instead

locateEntityPersister

@Deprecated(since="6.0")
EntityPersister locateEntityPersister(String byName)

Deprecated.

- use getEntityDescriptor(String) instead

Locate the entity persister by name.

Returns:

The located EntityPersister, never null

Throws:

UnknownEntityTypeException - If a matching EntityPersister cannot be located
