构造器详细资料

PooledSoftReference

public PooledSoftReference(java.lang.ref.SoftReference<T> reference)

Creates a new PooledSoftReference wrapping the provided reference.

参数:

reference - SoftReference to be managed by the pool

方法详细资料

getObject

public T getObject()

Gets the object that the wrapped SoftReference refers to.

Note that if the reference has been cleared, this method will return null.

指定者:

getObject 在接口中 PooledObject<T>

覆盖:

getObject 在类中 DefaultPooledObject<T>

返回:

Object referred to by the SoftReference

getReference

public java.lang.ref.SoftReference<T> getReference()

Gets the SoftReference wrapped by this object.

返回:

underlying SoftReference

setReference

public void setReference(java.lang.ref.SoftReference<T> reference)

Sets the wrapped reference.

This method exists to allow a new, non-registered reference to be held by the pool to track objects that have been checked out of the pool. The actual parameter should be a reference to the same object that getObject() returns before calling this method.

参数:

reference - new reference

toString

public java.lang.String toString()

Provides a String form of the wrapper for debug purposes. The format is not fixed and may change at any time.

指定者:

toString 在接口中 PooledObject<T>

覆盖:

toString 在类中 DefaultPooledObject<T>
