Example 50 with IdentityHashMap

use of java.util.IdentityHashMap in project robovm by robovm.

the class IdentityHashMapTest method setUp.

/**
     * Sets up the fixture, for example, open a network connection. This method
     * is called before a test is executed.
     */
protected void setUp() {
