isAppropriate

public boolean isAppropriate(Field field)

Determines if the resolver is appropriate for the given field. This implementation returns true if the field represents a collection relationship.

Specified by:

isAppropriate in interface TypeFieldResolver

Parameters:

field - the field to be evaluated for custom injection

Returns:

true if the field represents a collection 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 retrieves the associated entities from the database based on the collection relationship type.

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 value to be injected into the field, typically a collection of associated entities

Throws:

BibernateGeneralException - if an error occurs while retrieving the associated entities
