copyTo
public java.lang.Object copyTo(java.lang.Object target)
- 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.
