Returns a clone of the object.

Usage

From source file:org.jfree.data.KeyedObject.java

/**
 * Returns a clone of this object.  It is assumed that the key is an
 * immutable object, so it is not deep-cloned.  The object is deep-cloned
 * if it implements {@link PublicCloneable}, otherwise a shallow clone is
 * made.//  w w w.  j a  v a 2  s  . c  o  m
 *
 * @return A clone.
 *
 * @throws CloneNotSupportedException if there is a problem cloning.

        PublicCloneable pc = (PublicCloneable) this.object;
