    Returns the maximum amount of time (in milliseconds) the borrowObject() method should block before throwing an exception when the pool is exhausted and the "when exhausted" action is WHEN_EXHAUSTED_BLOCK. When less than or equal to 0, the borrowObject() method may block indefinitely.

public void setMaxIdle(int maxIdle)
```
    Sets the cap on the number of "idle" instances in the pool. If maxIdle is set too low on heavily loaded systems it is possible you will see objects being destroyed and almost immediately new objects being created. This is a result of the active threads momentarily returning objects faster than they are requesting them them, causing the number of idle objects to rise above maxIdle. The best value for maxIdle for heavily loaded system will vary but the default is a good starting point.

    Sets the LIFO property of the pool. True means that borrowObject returns the most recently used ("last in") idle object in the pool (if there are idle instances available). False means that the pool behaves as a FIFO queue - objects are taken from the idle object pool in the order that they are returned to the pool.

  - borrowObject
```
public T borrowObject()
               throws java.lang.Exception
```
    Borrows an object from the pool.
    
    If there is an idle instance available in the pool, then either the most-recently returned (if lifo == true) or "oldest" (lifo == false) instance sitting idle in the pool will be activated and returned. If activation fails, or testOnBorrow is set to true and validation fails, the instance is destroyed and the next available instance is examined. This continues until either a valid instance is returned or there are no more idle instances available.
    
    If there are no idle instances available in the pool, behavior depends on the maxActive and (if applicable) whenExhaustedAction and maxWait properties. If the number of instances checked out from the pool is less than maxActive, a new instance is created, activated and (if applicable) validated and returned to the caller.
    
    If the pool is exhausted (no available idle instances and no capacity to create new ones), this method will either block (WHEN_EXHAUSTED_BLOCK), throw a NoSuchElementException (WHEN_EXHAUSTED_FAIL), or grow (WHEN_EXHAUSTED_GROW - ignoring maxActive). The length of time that this method will block when whenExhaustedAction == WHEN_EXHAUSTED_BLOCK is determined by the maxWait property.
    
    When the pool is exhausted, multiple calling threads may be simultaneously blocked waiting for instances to become available. As of pool 1.5, a "fairness" algorithm has been implemented to ensure that threads receive available instances in request arrival order.

    By contract, obj must have been obtained using borrowObject or a related method as defined in an implementation or sub-interface.
    
    This method should be used when an object that has been borrowed is determined (due to an exception or other problem) to be invalid.

```
public void returnObject(T obj)

    Returns an object instance to the pool.
    
    If maxIdle is set to a positive value and the number of idle instances has reached this value, the returning instance is destroyed.
    
    If testOnReturn == true, the returning instance is validated before being returned to the idle instance pool. In this case, if validation fails, the instance is destroyed.
    
    Note: There is no guard to prevent an object being returned to the pool multiple times. Clients are expected to discard references to returned objects and ensure that an object is not returned to the pool multiple times in sequence (i.e., without being borrowed again between returns). Violating this contract will result in the same object appearing multiple times in the pool and pool counters (numActive, numIdle) returning incorrect values.

    Sets the factory this pool uses to create new instances. Trying to change the factory while there are borrowed objects will throw an IllegalStateException. If there are instances idle in the pool when this method is invoked, these will be destroyed using the original factory.
    
    指定者:
    
    setFactory 在接口中 ObjectPool<T>
    
    覆盖:
    
    setFactory 在类中 BaseObjectPool<T>
    
    参数:
    
    factory - the PoolableObjectFactory used to create new instances.
    
    抛出:
    
    java.lang.IllegalStateException - when the factory cannot be set at this time
  - evict
```
public void evict()
           throws java.lang.Exception
```
    Perform numTests idle object eviction tests, evicting examined objects that meet the criteria for eviction. If testWhileIdle is true, examined objects are validated when visited (and removed if invalid); otherwise only objects that have been idle for more than minEvicableIdletimeMillis are removed.
    
    Successive activations of this method examine objects in in sequence, cycling through objects in oldest-to-youngest order.
    
    抛出:
    
    java.lang.Exception - if the pool is closed or eviction fails.
  - addObject
```
public void addObject()
               throws java.lang.Exception
```
    Create an object, and place it into the pool. addObject() is useful for "pre-loading" a pool with idle objects.
    
    指定者:
    
    addObject 在接口中 ObjectPool<T>
    
    覆盖:
    
    addObject 在类中 BaseObjectPool<T>
    
    抛出:
    
    java.lang.UnsupportedOperationException - UnsupportedOperationException
    
    java.lang.Exception - Exception
