to take the appropriate locks when necessary.

been registered using
this put method .
|
int | getInt(Object key) - Returns the element identified by key, or Integer.MAX_VALUE if none exists,
or if it has been registered using
this put method .
|
int | getInt(int key) - Returns the element identified by key, or Integer.MAX_VALUE if none exists,
or if it has been registered using
