Method Detail

setValueFrom

public void setValueFrom(java.lang.Object o)

Description copied from interface: SCO

Assigns the value of this second-class object from an existing object of the same or compatible type.

Specified by:

setValueFrom in interface SCO

Parameters:

o - the object from which to copy the value.

getFieldName

public java.lang.String getFieldName()

Description copied from interface: SCO

Returns the field name.

Specified by:

getFieldName in interface SCO

Returns:

field name

getOwner

public java.lang.Object getOwner()

Description copied from interface: SCO

Returns the owner object of the SCO instance.

Specified by:

getOwner in interface SCO

Returns:

owner object

unsetOwner

public void unsetOwner()

Description copied from interface: SCO

Nullifies references to the owner Object and Field.

Specified by:

unsetOwner in interface SCO

applyUpdates

public void applyUpdates()

Description copied from interface: SCO

Applies any pending updates for this object to the data store.

Specified by:

applyUpdates in interface SCO

makeDirty

public void makeDirty()

Description copied from interface: SCO

Marks object dirty.

Specified by:

makeDirty in interface SCO

newQueryStatement

public QueryStatement newQueryStatement()

Description copied from interface: Queryable

Returns a prototypical query statement over the underlying collection.

The returned query statement selects all applicable rows from the relevant base table(s) and the column that represents the element or element ID. The statement can then be modified to join additional tables, select more columns, add WHERE conditions, etc.

Specified by:

newQueryStatement in interface Queryable

Returns:

The new prototypical query statement.

newQueryStatement

public QueryStatement newQueryStatement(java.lang.Class candidateClass)

Description copied from interface: Queryable

Returns a prototypical query statement over the underlying collection, pre-filtered to include only objects of the specified class.

Specified by:

newQueryStatement in interface Queryable

Returns:

The new prototypical query statement.

See Also:

Queryable.newQueryStatement()

newResultObjectFactory

public Query.ResultObjectFactory newResultObjectFactory(QueryStatement stmt)

Description copied from interface: Queryable

Returns a suitable query result factory for results produced by the specified query.

The stmt argument must have been obtained by a previous call to newQueryStatement() on the same Queryable.

Specified by:

newResultObjectFactory in interface Queryable

Returns:

A factory for creating PersistenceCapable objects from query results.

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.

add

public boolean add(java.lang.Object element)

Specified by:

add in interface java.util.Set

remove

public boolean remove(java.lang.Object element)

Specified by:

remove in interface java.util.Set

clear

public void clear()

Specified by:

clear in interface java.util.Set
