io.github.blyznytsiaorg.bibernate.entity.type.LazyEntityFieldResolver

All Implemented Interfaces:

TypeFieldResolver

public class LazyEntityFieldResolver
extends Object
implements TypeFieldResolver

Implementation of TypeFieldResolver for resolving custom injection values for lazy-loaded entity fields.

This resolver is responsible for determining if a given field of an entity class represents a lazy-loaded relationship and preparing the value to be injected into the field.

LazyEntityFieldResolver

public LazyEntityFieldResolver()

Method Details

isAppropriate

public boolean isAppropriate(Field field)

Determines if the resolver is appropriate for the given field. This implementation checks if the field is annotated with ManyToOne or OneToOne with lazy fetch type.

Specified by:

isAppropriate in interface TypeFieldResolver

Parameters:

field - the field to be evaluated for custom injection

Returns:

true if the field represents a lazy-loaded relationship, false otherwise

prepareValueForFieldInjection

public Object prepareValueForFieldInjection(Field field,
 ResultSet resultSet,
 Object entity,
 EntityPersistent entityPersistent)

Prepares the value to be injected into the specified field of the entity. This implementation creates a lazy-loading proxy for the entity field, resolving the entity value when accessed.

Specified by:

prepareValueForFieldInjection in interface TypeFieldResolver

Parameters:

field - the field to receive the injected value

resultSet - the result set containing the data from which the value will be extracted

entity - the entity object to which the field belongs

entityPersistent - the persistent metadata associated with the entity

Returns:

the lazy-loading proxy for the entity field
