Usage

From source file:com.lonepulse.robozombie.proxy.Zombie.java

/**
 * <p>Accepts an object and scans it for {@link Bite} annotations. If found, a <b>thread-safe proxy</b> 
 * for the endpoint interface will be injected.</p>
 * /*www.j  a  va 2 s . com*/
 * <p>Injection targets will be searched up an inheritance hierarchy until a type is found which is 
 * <b>not</b> in a package whose name starts with the given package prefixes.</p>
 * <br>
 * <b>Usage:</b>
 * <br><br>
 * <ul>
 * <li>
 * <h5>Property Injection</h5>

 * @param moreVictims
 *          more unsuspecting objects with endpoint references to be infected
