TDirectoryCacheDependency performs dependency checking based on the
modification time of the files contained in the specified directory.
The directory being checked is specified via {@link setDirectory Directory}.
By default, all files under the specified directory and subdirectories
will be checked. If the last modification time of any of them is changed
or if different number of files are contained in a directory, the dependency
is reported as changed. By specifying {@link setRecursiveCheck RecursiveCheck}
and {@link setRecursiveLevel RecursiveLevel}, one can limit the checking
to a certain depth of the subdirectories.
public function testRecursiveLevel()
{
$directory = realpath(dirname(__FILE__) . '/temp');
$dependency = new TDirectoryCacheDependency(dirname(__FILE__) . '/temp');
$this->assertEquals($dependency->getRecursiveLevel(), -1);
$dependency->setRecursiveLevel(5);
$this->assertEquals($dependency->getRecursiveLevel(), 5);
