Constructor Detail

Point

public Point(StateManager ownerSM,
             java.lang.String fieldName)

Creates a Point object. Assigns owning object and field name.

Parameters:

ownerSM - the owning object

fieldName - the owning field name

Method Detail

clone

public java.lang.Object clone()

Creates and returns a copy of this object.

Mutable second-class Objects are required to provide a public clone method in order to allow for copying PersistenceCapable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException.

Specified by:

clone in interface SCO

Overrides:

clone in class java.awt.geom.Point2D

Returns:

A clone of the object

setLocation

public void setLocation(double x,
                        double y)

Mutator for the location.

Overrides:

setLocation in class java.awt.Point

Parameters:

x - The location x

y - The location y

setLocation

public void setLocation(int x,
                        int y)

Mutator for the location.

Overrides:

setLocation in class java.awt.Point

Parameters:

x - The location x

y - The location y

setLocation

public void setLocation(java.awt.Point point)

Mutator for the location.

Overrides:

setLocation in class java.awt.Point

Parameters:

point - The location

setLocation

public void setLocation(java.awt.geom.Point2D point)

Mutator for the location.

Overrides:

setLocation in class java.awt.geom.Point2D

Parameters:

point - The location

move

public void move(int x,
                 int y)

Overrides:

move in class java.awt.Point

translate

public void translate(int dx,
                      int dy)

Overrides:

translate in class java.awt.Point

setValueFrom

public void setValueFrom(java.lang.Object o,
                         boolean forUpdate)

Mutator for the value, using an object.

Specified by:

setValueFrom in interface SCO

Parameters:

o - The Object

forUpdate - Whether to update the datastore with this value

unsetOwner

public void unsetOwner()

Utility to unset the owner.

Specified by:

unsetOwner in interface SCO

getOwner

public java.lang.Object getOwner()

Accessor for the owner.

Specified by:

getOwner in interface SCO

Returns:

The owner

getFieldName

public java.lang.String getFieldName()

Accessor for the field name

Specified by:

getFieldName in interface SCO

Returns:

The field name

makeDirty

public void makeDirty()

Utility to mark the object as dirty

runReachability

public void runReachability(java.util.Set reachables)

Method to run reachability on this SCO.

Specified by:

runReachability in interface SCO

Parameters:

reachables - List of StateManagers reachable so far

makeTransient

public void makeTransient(FetchPlanState state)

Method to make transient this object.

Specified by:

makeTransient in interface SCO

Parameters:

state - State for the fetchplan process

detach

public void detach(FetchPlanState state)

Method to detach this object.

Specified by:

detach in interface SCO

Parameters:

state - State for the detachment process

detachCopy

public java.lang.Object detachCopy(FetchPlanState state)

Method to detach a copy of this object.

Specified by:

detachCopy in interface SCO

Parameters:

state - State for detachment process

Returns:

The detached object

attachCopy

public void attachCopy(java.lang.Object value)

Method to attach the passed value.

Specified by:

attachCopy in interface SCO

Parameters:

value - The new value

writeReplace

protected java.lang.Object writeReplace()
                                 throws java.io.ObjectStreamException

The writeReplace method is called when ObjectOutputStream is preparing to write the object to the stream. The ObjectOutputStream checks whether the class defines the writeReplace method. If the method is defined, the writeReplace method is called to allow the object to designate its replacement in the stream. The object returned should be either of the same type as the object passed in or an object that when read and resolved will result in an object of a type that is compatible with all references to the object.

Returns:

the replaced object

Throws:

java.io.ObjectStreamException
