Constructor Detail

SqlTime

public SqlTime(ObjectProvider op,
       AbstractMemberMetaData mmd)

Creates a SqlTime object that represents the time at which it was allocated.

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 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 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 SCO

Returns:

The unwrapped value

unsetOwner

public void unsetOwner()

Utility to unset the owner.

Specified by:

unsetOwner in interface SCO

getOwner

public Object getOwner()

Accessor for the owner.

Specified by:

getOwner in interface SCO

Returns:

The owner

getFieldName

public 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

detachCopy

public 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(Object value)

Method to return an attached version for the passed ObjectProvider and field, using the passed value.

Specified by:

attachCopy in interface 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 PersistenceCapable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException.

Specified by:

clone in interface SCO

Overrides:

clone in class Date

Returns:

Clone of the object

setTime

public void setTime(long time)

Sets the time of this Time object to the specified value. This Time object is modified so that it represents a point in time with the hour, minute, second as specified.

Overrides:

setTime in class Time

Parameters:

time - millisecs since 1 Jan 1970, 00:00:00 GMT

Calendar

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
