public Entity()

Method Detail

getId

public long getId()

Get the unique identifier of this object.

This identifier is unique per entity type (the first sub-class of this class having an own table - which is usually the direct sub-class of Entity).

This identifier is assigned when the object is persisted into the DB.

Returns:

the unique identifier of this object.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getCreated

public Date getCreated()

Gets the timestamp of the creation of this entity.

Returns:

the timestamp of the creation of this entity. Never null.

setCreated

protected void setCreated(Date created)

Sets the timestamp of the creation of this entity.

Important: You should normally never invoke this method! The created property is supposed to be read-only (assigned once during object creation and never again). This setter merely exists for extraordinary, unforeseen use cases as well as tests.

Parameters:

created - the timestamp of the creation of this entity. Must not be null.

public Date getChanged()

setChanged

public void setChanged(Date changed)

Description copied from interface: AutoTrackChanged
