## NAME
    [Cache::MemoryCache](https://www.chedong.com/phpMan.php/perldoc/Cache%3A%3AMemoryCache/markdown) -- implements the Cache interface.

## DESCRIPTION
    The MemoryCache class implements the Cache interface. This cache stores data on a per-process
    basis. This is the fastest of the cache implementations, but data can not be shared between
    processes with the MemoryCache. However, the data will remain in the cache until cleared, it
    expires, or the process dies. The cache object simply going out of scope will not destroy the
    data.

## SYNOPSIS
      use [Cache::MemoryCache](https://www.chedong.com/phpMan.php/perldoc/Cache%3A%3AMemoryCache/markdown);

      my $cache = new [Cache::MemoryCache](https://www.chedong.com/phpMan.php/perldoc/Cache%3A%3AMemoryCache/markdown)( { 'namespace' => 'MyNamespace',
                                            'default_expires_in' => 600 } );
