Interface PHPStan\Analyser\ResultCache\ResultCacheValueExtension

A value outside of the analysed code that rules and extensions read - whether a service exists in a DI container, the value of a configuration parameter, the contents of a file.

A rule or an extension reading such a value declares it:

$scope->trackValueDependency(MyExtension::class, $key);

The result cache then records the value, and re-analyses the files that declared it when it is different, and only them. Compared to ResultCacheMetaExtension, which discards the whole result cache on any change, only what was actually asked about matters, and only for the files asking.

To register it in the configuration file use the phpstan.resultCacheValueExtension service tag:

services:
	-
		class: App\PHPStan\MyExtension
		tags:
			- phpstan.resultCacheValueExtension

Methods
`public`	`getValue(string $key): string` The current value for the key - compared with the one recorded by the last analysis. A long value is better hashed. The current value for the key - compared with the one recorded by the last analysis. A long value is better hashed. `getValue` is invoked before `bootstrapFiles` are included.	#
`public`	`keyToResultCache(string $key): string` The key as the result cache stores it. A key that is a file path is best stored relative to the project, so that the result cache survives a moved checkout. The key as the result cache stores it.

`public`	`keyFromResultCache(string $storedKey): string` The key back from the result cache - the reverse of keyToResultCache(). The key back from the result cache - the reverse of keyToResultCache().	#
