Caching

Generated solutions can be cached if the solution provider in use is cacheable (see EliasHaeussler\Typo3Solver\ProblemSolving\Solution\Provider\SolutionProvider::isCacheable). For this, a filesystem-based solution cache is implemented. In addition, an exception cache is provided which stores exceptions when solution streaming is active.

Note

All caches are low-level caches and cannot be configured.

class EliasHaeussler\Typo3Solver\Cache\ExceptionsCache

Low-level cache manager for exceptions. This class is only used in combination with solution streaming.

Note

This cache writes to var/cache/data/tx_solver/exceptions.php.

get($entryIdentifier)

Get exception by cache identifier. If no cache with the given identifier exists, null is returned.

Parameters

  • $entryIdentifier (string) -- Cache identifier of the exception to look up

Return type

Throwable|null

getIdentifier($exception)

Get calculated exception identifier of the given exception.

Parameters

  • $exception (Throwable) -- Exception to calculate a cache identifier

Return type

string

set($exception)

Add the given exception to the exceptions cache and return the associated cache identifier.

Parameters

  • $exception (Throwable) -- The exception to be cached

Return type

string

flush()

Remove all cached exceptions.

class EliasHaeussler\Typo3Solver\Cache\SolutionsCache

Low-level cache manager for solutions. This class is used in combination with EliasHaeussler\Typo3Solver\ProblemSolving\Solution\Provider\CacheSolutionProvider.

Note

This cache writes to var/cache/data/tx_solver/solutions.php.

get($problem)

Get cached solution for the given problem. If no solution exists in cache, null is returned.

Parameters

  • $problem (EliasHaeussler\Typo3Solver\ProblemSolving\Problem\Problem) -- Problem to get a cached solution for

Return type

EliasHaeussler\Typo3Solver\ProblemSolving\Solution\Solution|null

set($problem, $solution)

Add the given solution to the solutions cache and use the given problem to generate the cache identifier.

Parameters

  • $problem (EliasHaeussler\Typo3Solver\ProblemSolving\Problem\Problem) -- The problem of the solution to be cached

  • $solution (EliasHaeussler\Typo3Solver\ProblemSolving\Solution\Solution) -- The solution to be cached

flush()

Remove all cached solutions.
