The Commons Attributes source code

package org.apache.commons.attributes;

 * Marks an attribute class as being sealable. When an instance of an attribute
 * class is created it goes through the following phases:
 * <ol>
 * <li>Its constructor is called with all non-named parameters in the attribute declaration.
 * <li>Its setters are called according to the named parameters in the declaration.
 * </ol>
 * This alone poses a security risk, as a client can call setters on an attribute as well,
 * and thus make class attributes mutable. In order to notify the attribute class that construction
 * and initialization is completed, the attribute runtime system will test if it implements Sealable,
 * and of so, invoke {@link #seal()} on the attribute instance.
 * @see DefaultSealable
 * @since 2.1
public interface Sealable {
     * Called to indicate that construction and initialization of this attribute instance
     * is completed, and that the attribute instance should become read-only.
 * @since 2.1
    public void seal ();
