| <P> |
| This class implements a HashMap which has limited synchronization. |
| In particular mutators are generally synchronized while accessors |
| are generally not. Additionally the Iterators returned by this |
| class are not "fail-fast", but instead try to continue to iterate |
| over the data structure after changes have been made. |
| The synchronization semantics are built right in to the |
| implementation rather than using a delegating wrapper like the |
| other collection classes do because it wasn't clear to me that the |
| how the two should be seperated or that it would be useful to do |
| so. This can probably be a topic for further debate in the future. |
| This class is based heavily on the HashMap class in the Java |
| collections package. |
