ObjectMemoizer

public ObjectMemoizer(java.lang.Object obj)
               throws java.io.IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
ObjectMemoizer theObjectMemoizer = (ObjectMemoizer) obj;

Construct a ObjectMemoizer using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to ObjectMemoizer.
