The <info>%command.name%</info> command warms up cache by specified parameters. |
|
38
|
|
|
|
|
39
|
|
|
A warmer can be configured for one or more filter set. A warmer should return a list of paths. |
|
40
|
|
|
This command gets the paths from warmer and create cache (i.e. filtered image) for each filter configured for given warmer. |
|
41
|
|
|
|
|
42
|
|
|
Warmers should be separated by spaces: |
|
43
|
|
|
<info>php app/console %command.name% warmer1 warmer2</info> |
|
44
|
|
|
All cache for a given `warmers` will be warmed up |
|
45
|
|
|
|
|
46
|
|
|
<info>php app/console %command.name%</info> |
|
47
|
|
|
Cache for all warmers will be warmed up when executing this command without parameters. |
|
48
|
|
|
|
|
49
|
|
|
Note, that <info>--force</info> option will force regeneration of the cache only if warmer returns the path. |
|
50
|
|
|
Generally, there should be NO need to use this option, instead, use <info>liip:imagine:cache:remove</info> command to clear cache. |
|
51
|
|
|
Then run this command to warm-up the cache |

If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check:
If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
