Method Detail

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.
