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

org.apache.commons.pool.ObjectPool.borrowObject()
Obtain an instance from my pool. By contract, clients MUST return the borrowed instance using {@link #returnObject(java.lang.Object) returnObject}or a related method as defined in an implementation or sub-interface.
The behaviour of this method when the pool has been exhausted is not specified (although it may be specified by implementations). @return an instance from my pool.
