Constructor Detail

Point

public Point(org.datanucleus.state.ObjectProvider op,
             org.datanucleus.metadata.AbstractMemberMetaData mmd)

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

Parameters:

op - ObjectProvider for the owning object

mmd - Metadata for the member

Method Detail

initialise

public void initialise()

Method to initialise the SCO for use.

Specified by:

initialise in interface org.datanucleus.store.types.SCO

initialise

public void initialise(Object o,
                       boolean forInsert,
                       boolean forUpdate)

Method to initialise the SCO from an existing value.

Specified by:

initialise in interface org.datanucleus.store.types.SCO

Parameters:

o - The Object

forInsert - Whether the object needs inserting in the datastore with this value

forUpdate - Whether to update the datastore with this value

getValue

public Object getValue()

Accessor for the unwrapped value that we are wrapping.

Specified by:

getValue in interface org.datanucleus.store.types.SCO

Returns:

The unwrapped value

unsetOwner

public void unsetOwner()

Utility to unset the owner.

Specified by:

unsetOwner in interface org.datanucleus.store.types.SCO

getOwner

public Object getOwner()

Accessor for the owner.

Specified by:

getOwner in interface org.datanucleus.store.types.SCO

Returns:

The owner

getFieldName

public String getFieldName()

Accessor for the field name

Specified by:

getFieldName in interface org.datanucleus.store.types.SCO

Returns:

The field name

makeDirty

public void makeDirty()

Utility to mark the object as dirty

detachCopy

public Object detachCopy(org.datanucleus.state.FetchPlanState state)

Method to detach a copy of this object.

Specified by:

detachCopy in interface org.datanucleus.store.types.SCO

Parameters:

state - State for detachment process

Returns:

The detached object

attachCopy

public void attachCopy(Object value)

Method to attach the passed value.

Specified by:

attachCopy in interface org.datanucleus.store.types.SCO

Parameters:

value - The new value

clone

public 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 persistable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException.

Specified by:

clone in interface org.datanucleus.store.types.SCO

Overrides:

clone in class Point2D

Returns:

A clone of the object

setLocation

public void setLocation(double x,
                        double y)

Mutator for the location.

Overrides:

setLocation in class 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 Point

Parameters:

x - The location x

y - The location y

setLocation

public void setLocation(Point point)

Mutator for the location.

Overrides:

setLocation in class Point

Parameters:

point - The location

setLocation

public void setLocation(Point2D point)

Mutator for the location.

Overrides:

setLocation in class Point2D

Parameters:

point - The location

move

public void move(int x,
                 int y)

Overrides:

move in class Point

translate

public void translate(int dx,
                      int dy)

Overrides:

translate in class Point

writeReplace

protected Object writeReplace()
                       throws 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:

ObjectStreamException - when problem occurs on serialization
