resetIDLookup method

void resetIDLookup()

Reset the idLookup table. If it is subsequently accessed, it will be rebuilt automatically, in an O(n) operation on the number of nodes in the DOM.

Client code can change the DOM, adding or removing nodes, or changing the id values of nodes. The lookup table is not automatically reset when this happens. After one or more such modifications, client code should call this method if it plans to subsequently look up nodes by name.

Implementation

void resetIDLookup() {
  _idLookup = null;
}
