public interface DeepCopyable

This interface provides a way to do polymorphic copying.

An interface (a class) that extends (implements) this interface should override the return type of deepCopy() in the interface (class) itself to provide as much information as possible to avoid unnecessary casting.

For example,

 public interface Matrix extends DeepCopyable {
     ...
     Matrix deepCopy();
 }

java.lang.Object	deepCopy() The implementation returns an instance created from this by the copy constructor of the class, or just this if the instance itself is immutable.

Method Detail

deepCopy

java.lang.Object deepCopy()

The implementation returns an instance created from this by the copy constructor of the class, or just this if the instance itself is immutable.

Returns:

an independent (deep) copy of the instance
