- Copy constructor.
copyTo
public java.lang.Object copyTo(java.lang.Object object)
- Description copied from interface:
Copyable
- Copies the internal state of
this
object to the specified copy
. If copy
is null
, then this method should create a new instance of this
class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.
Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this
object's state was copied.
There is a standard implementation pattern for the copyTo
method that helps avoid problems that arise when a Copyable
object is subclassed. The pattern is:
public Object copyTo( Object target )
{
final <this_class> copy =
target != null ? (<this_class>) target : new <this_class>();
copyToImpl( copy );
return copy;
} protected final void copyToImpl( <this_class> copy ) { super.copyToImpl( copy ); // if necessary // put code here for copying the properties of <this_class> }
The parameter passed into the copyToImpl
method is the same type of this
class. The responsibility of copyToImpl
is to copy the state of this
class through direct access of the fields. The copyToImpl
method should not use getters and setters since these may be overridden, causing the state of this
class to be incompletely copied.
-
- Specified by:
copyTo
in interface Copyable
-
- Parameters:
object
- The target object to which the state of this
object should be copied. If target
is null
, then the copyTo
method will return a new instance of this
class.
- Returns:
- The object to which the state of
this
object was copied. If the target
was non-null
, then the return value is the same as the target
object that was passed in; otherwise, the return value is a new instance of this
class.

markDirty
public void markDirty(boolean dirty)
- Description copied from interface:
Dirtyable
- Marks the data with the specified dirty state. This method is called
markDirty(...)
instead of setDirty(...)
so that the JavaBeans Introspector
will not mistakenly identify "dirty" as a JavaBean property.
-
- Specified by:
markDirty
in interface Dirtyable
- Overrides:
markDirty
in class DataElement
isDirty
public boolean isDirty()
- Description copied from interface:
Dirtyable
- True if the data in the object has been modified.
-
- Specified by:
isDirty
in interface Dirtyable
- Overrides:
isDirty
in class DataElement
setOwner
public void setOwner(Dirtyable owner)
- Description copied from interface:
SubDirtyable
- This method should be called to set the document in which a
SubDirtyable
implementation will be persisted.
-
- Specified by:
setOwner
in interface SubDirtyable
-
- Parameters:
owner
- The Dirtyable
object in which this SubDirtyable
will be saved.
notifyObservers
public void notifyObservers(java.lang.Object subject,
UpdateMessage change)
- Description copied from interface:
Subject
- Notifies all observers that the state of the subject has changed.
-
- Specified by:
notifyObservers
in interface Subject
-
- Parameters:
subject
- the subject whose state has changed.
change
- what changed.
detach
public void detach(Observer observer)
- Description copied from interface:
Subject
- Unregisters an observer that is not interested anymore in being notified when the internal state of the class implementing the
Subject
interface changes. Implementors should do nothing when the same observer is removed more than once.
-
- Specified by:
detach
in interface Subject
-
- Parameters:
observer
- the Observer
disinterested in change notification messages.
attach
public void attach(Observer observer)
- Description copied from interface:
Subject
- Registers an observer interested in being notified when the internal state of the class implementing the
Subject
interface changes. Implementors should do nothing when the same observer is added more than once.
-
- Specified by:
attach
in interface Subject
-
- Parameters:
observer
- the Observer
interested in change notification messages.
