CChainedCacheDependency

system.caching.dependencies
继承 class CChainedCacheDependency » CComponent
实现 ICacheDependency
可用自 1.0
源码 framework/caching/dependencies/CChainedCacheDependency.php
CChainedCacheDependency represents a list of cache dependencies.

If any of the dependencies reports a dependency change, CChainedCacheDependency will return true for the checking.

To add dependencies to CChainedCacheDependency, use Dependencies which gives a CTypedList instance and can be used like an array (see CList for more details}).

方法详情

__construct() 方法 (自版本 v1.1.4 可用)
public void __construct(array $dependencies=array ( ))
$dependencies array the dependencies to be added to this chain.
源码: framework/caching/dependencies/CChainedCacheDependency.php#37 (显示)
public function __construct($dependencies=array())
{
    if(!empty(
$dependencies))
        
$this->setDependencies($dependencies);
}

Constructor.

evaluateDependency() 方法
public void evaluateDependency()

public function evaluateDependency()
{
    if(
$this->_dependencies!==null)
    {
        foreach(
$this->_dependencies as $dependency)
            
$dependency->evaluateDependency();
    }
}

Evaluates the dependency by generating and saving the data related with dependency.

getDependencies() 方法
public CTypedList getDependencies()
{return} CTypedList list of dependency objects
源码: framework/caching/dependencies/CChainedCacheDependency.php#46 (显示)
public function getDependencies()
{

$this->_dependencies=new CTypedList('ICacheDependency');
    return 
$this->_dependencies;
}

getHasChanged() 方法
public boolean getHasChanged()
{return} boolean whether the dependency is changed or not.
源码: framework/caching/dependencies/CChainedCacheDependency.php#87 (显示)
public function getHasChanged()
{

                return 
true;
    }
    return 
false;
}

Performs the actual dependency checking. This method returns true if any of the dependency objects reports a dependency change.
