ResourceCheckerConfigCache

class ResourceCheckerConfigCache implements ConfigCacheInterface

ResourceCheckerConfigCache uses instances of ResourceCheckerInterface to check whether cached data is still fresh.

Methods

	__construct(string $file, array $resourceCheckers = array())
string	getPath() Gets the cache file path.
bool	isFresh() Checks if the cache is still fresh.
	write(string $content, array $metadata = null) Writes cache.

Details

__construct(string $file, array $resourceCheckers = array())

Parameters

string	$file	The absolute cache path
array	$resourceCheckers	The ResourceCheckers to use for the freshness check

string getPath()

Gets the cache file path.

Return Value

string

The cache file path

bool isFresh()

Checks if the cache is still fresh.

This implementation will make a decision solely based on the ResourceCheckers passed in the constructor.

The first ResourceChecker that supports a given resource is considered authoritative. Resources with no matching ResourceChecker will silently be ignored and considered fresh.

Return Value

bool	Whether the cache is still fresh.

write(string $content, array $metadata = null)

Writes cache.

Parameters

string	$content	The content to write into the cache
array	$metadata	An array of ResourceInterface instances

Exceptions

RuntimeException

When cache file can't be written
