Document

Borrows an object from the keyed pool associated with the given key.

If there is an idle instance available in the pool associated with the given key, then either the most-recently returned (if #getLifo() lifo == true) or "oldest" (lifo == false) instance sitting idle in the pool will be activated and returned.

Usage

From source file:TestKeyedObjectPool.java

 public static void main(String args[]) throws Exception {

   GenericKeyedObjectPool pool = new GenericKeyedObjectPool();
   pool.setFactory(new SkilledEmployeeFactory());

   pool.addObject("Java");
   pool.addObject("Java");
   pool.addObject("VB");
   pool.addObject("C++");

   System.err.println("Number of Java employees in pool: " +
     pool.getNumIdle("Java") + " out of total employees: " +
     pool.getNumIdle());/* www  .j a v  a 2  s .  c o m*/

   Employee employee = (Employee)pool.borrowObject("Java");

   employee.doWork();

   System.err.println("Employee: "  + employee);

   pool.returnObject("Java", employee);

   System.err.println("Number of Java employees in pool: " +
     pool.getNumIdle("Java") + " out of total employees: " +
     pool.getNumIdle());
