Package io.jmix.core.entity

Class NullableIdEntityEntry

java.lang.Object

io.jmix.core.entity.BaseEntityEntry

io.jmix.core.entity.NullableIdEntityEntry

All Implemented Interfaces:

EntityEntry, Serializable, Cloneable

public abstract class NullableIdEntityEntry
extends BaseEntityEntry

Used by enhancing process. Subclass of NullableIdEntityEntry will be created for entity that:

• has primary key (an attribute annotated with Id, EmbeddedId or JmixId)
• Primary key is not annotated with JmixGeneratedValue
• There is no UUID attribute annotated with JmixGeneratedValue

See Also:

• Serialized Form

Method Summary

Modifier and Type	Method	Description
void	copy(EntityEntry entry)	Copies the state of entity entry.
Object	getGeneratedIdOrNull()	GeneratedId will be determined at enhancing time as follows: primary key (Id, EmbeddedId or JmixId attribute) will be used if it has JmixGeneratedValue annotation, any other UUID JmixGeneratedValue property will be chosen if primary key doesn't have JmixGeneratedValue annotation, primary key or some synthetic id will be used if there is no JmixGeneratedValue satisfiyng conditions below (see EntityEntry implementations for details). This algorithm used for BaseEntityEntry and NullableIdEntityEntry.
int	hashCode()
void	setGeneratedId(Object id)	GeneratedId needed to identify entity, including hashCode calculation (see EntityInternals.hashCode(Entity)).

NullableIdEntityEntry

public NullableIdEntityEntry(Entity source)

Method Details

hashCode

public int hashCode()

Overrides:

hashCode in class BaseEntityEntry

getGeneratedIdOrNull

public Object getGeneratedIdOrNull()

Description copied from interface: EntityEntry

GeneratedId will be determined at enhancing time as follows:

1. primary key (Id, EmbeddedId or JmixId attribute) will be used if it has JmixGeneratedValue annotation,
2. any other UUID JmixGeneratedValue property will be chosen if primary key doesn't have JmixGeneratedValue annotation,
3. primary key or some synthetic id will be used if there is no JmixGeneratedValue satisfiyng conditions below (see EntityEntry implementations for details).

This algorithm used for BaseEntityEntry and NullableIdEntityEntry. See implementing classes description to clarify whether each of them will be used (directly or through subclass creation during enhancing process)

setGeneratedId

public void setGeneratedId(Object id)

Description copied from interface: EntityEntry

GeneratedId needed to identify entity, including hashCode calculation (see EntityInternals.hashCode(Entity)). Thus it has to be copied at the very beginning of entity copy creation.

copy

public void copy(EntityEntry entry)

Description copied from interface: EntityEntry

Copies the state of entity entry.

Specified by:

copy in interface EntityEntry

Overrides:

copy in class BaseEntityEntry
