<p>
|

ValueMap is a wrapper around a <a href="#dss_densemap">DenseMap</a> mapping
|
||||
Value*s (or subclasses) to another type. When a Value is deleted or RAUW'ed,
|
||||
ValueMap will update itself so the new version of the key is mapped to the same
|
||||
value, just as if the key were a WeakVH. You can configure exactly how this
|
||||
happens, and what else happens on these two events, by passing
|
||||
a <code>Config</code> parameter to the ValueMap template.</p>
