Examples of org.apache.commons.pool.ObjectPool.addObject()

org.apache.commons.pool.ObjectPool.addObject()
Create an object using my {@link #setFactory factory} or otherimplementation dependent mechanism, and place it into the pool. addObject() is useful for "pre-loading" a pool with idle objects. (Optional operation).

        ObjectPool pool = new StackObjectPool(factory, 2);
        factory.setThrowOnValidate(true);
        
        // addObject
        try {
            pool.addObject();
            fail("Expecting IntegerFactoryException");
        } catch (IntegerFactoryException ex) {
            assertEquals("validateObject", ex.getType());
        }
        assertEquals(0, pool.getNumIdle());

            fail("Expecting IntegerFactoryException");

            assertEquals("makeObject", ex.getType());
