Method Detail

getId

public Integer getId()

Description copied from interface: Entity

Returns the system ID.

Specified by:

getId in interface Entity

Returns:

ID > 0 for persistent entities, null for transient ones

setId

public void setId(Integer id)

Description copied from interface: Entity

Sets this entity's system ID.

Specified by:

setId in interface Entity

Parameters:

id - ID > 0 for persistent entities, null for transient ones

getCreateDate

public Date getCreateDate()

Specified by:

getCreateDate in interface Entity

Returns:

creation time stamp or null for transient entities

setCreateDate

public void setCreateDate(Date dateTime)

Sets the creation date and time.

The persistence framework automatically sets this property when a new entity is persisted.
Note that the value is managed by the persistence framework and may be generated by the database in the future.

The creation time stamp should never change once initialized.

Specified by:

setCreateDate in interface Entity

Parameters:

dateTime - creation time stamp

getLastModifiedDate

public Date getLastModifiedDate()

Specified by:

getLastModifiedDate in interface Entity

Returns:

last modification time stamp or null for transient entities

setLastModifiedDate

public void setLastModifiedDate(Date dateTime)

Sets the last modification date and time.

The persistence framework automatically sets this property to the same value as the createDate property when persisting a new entity and automatically updates it when saving an existing one.
Note that the value is managed by the persistence framework and may be generated by the database in the future.

Specified by:

setLastModifiedDate in interface Entity

Parameters:

dateTime - last modification time stamp

isNew

public boolean isNew()

Returns whether this instance represents a new transient instance.

Specified by:

isNew in interface Entity

Returns:

true if id is null

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

compareTo

public final int compareTo(Entity o)

Specified by:

compareTo in interface Comparable<Entity>

hashCode

public final int hashCode()

Overrides:

hashCode in class Object
