31 /** <P> This class implements a factory mechanism for the objects | |
32 created to wrap Addresses. It requires that the class passed in | |
33 implement a constructor taking with the following signature: </P> | |

35 <P> | |
36 <CODE> public <Type>(sun.jvm.hotspot.Address) | |
37 </CODE> | |
38 </P> | |
39 | |
40 <P> It is used to write shorter code when wrapping Addresses since | |
41 null checks are no longer necessary. In addition, it is a central | |
42 location where a canonicalizing map could be implemented if one | |
43 were desired (though the current system is designed to not require | |
44 one.) </P> | |
