namelesscoder / typo3-cms-multilevel-cache example snippets

// Simplest, most frequent use case: put runtime cache on top of existing cache
\NamelessCoder\MultilevelCache\CacheConfiguration::convert(
    'extbase_object',
    'cache_runtime', // First priority. A string means this is a reference to another cache that's already defined.
    'extbase_object' // Second priority. A fast way to operate this is to reference the original configuration.
);

// Bit more complex, manually define the second, third, fourth and so on backends that will be used:
\NamelessCoder\MultilevelCache\CacheConfiguration::convert(
    'extbase_object',
    'cache_runtime', // First priority. A string means this is a reference to another cache that's already defined.
