Method Details

setEntityDefaults

public void setEntityDefaults(Entity entity,
 boolean onlyMandatory)

Description copied from interface: EntityDefaultValueService

Sets the default values for fields and relations, but only where those fields and relations were not touched already (are null for fields and empty for relations). if onlyMandatory is true only defaults on mandatory fields and relations are set (non-nullable fields which are null are handled like mandatory fields).

Specified by:

setEntityDefaults in interface EntityDefaultValueService

getSetEntityDefaultsTask

public OptionalTask<Entity,Entity> getSetEntityDefaultsTask(boolean setNonNullableToEmpty)

Description copied from interface: EntityDefaultValueService

Get OptionalTask that sets entity defaults on an entity and returns it. If the parameter is true, non nullable fields will be set to empty after the default values have been set. (using the EntityModelUtils#setNonNullableToEmpty method)

Specified by:

getSetEntityDefaultsTask in interface EntityDefaultValueService

getBufferedSetEntityDefaultsTask

public OptionalTask<Entity,Entity> getBufferedSetEntityDefaultsTask(String entityModel)

Description copied from interface: EntityDefaultValueService

Get OptionalTask that sets entity defaults but loads them only once. A task that was created like this may only be used for entities of the model provided in the parameter and may result in faster entity creation if many entities of the same model are created.

Specified by:

getBufferedSetEntityDefaultsTask in interface EntityDefaultValueService

getDefaultValueForField

public Optional<Object> getDefaultValueForField(FieldModel fieldModel)

Description copied from interface: EntityDefaultValueService

Evaluates and returns the default value for the passed field model if available.

Specified by:

getDefaultValueForField in interface EntityDefaultValueService

getDefaultValuesForRelation

public Set<String> getDefaultValuesForRelation(RelationModel relationModel)

Description copied from interface: EntityDefaultValueService

Evaluates and returns the default values for the passed relation model as Set with primary keys as string if available.

Specified by:

getDefaultValuesForRelation in interface EntityDefaultValueService

getDefaultEntitiesForRelation

public List<Entity> getDefaultEntitiesForRelation(RelationModel relationModel)

Description copied from interface: EntityDefaultValueService

Same as EntityDefaultValueService.getDefaultValuesForRelation(RelationModel) but returns an EntityList instead of a Set. If no default entities can be found an empty EntityList will be returned.
