clean (line 149)

Clean some cache records

Available modes are : 'all' (default) => remove all cache entries ($tags is not used) 'old' => remove too old cache entries ($tags is not used) 'matchingTag' => remove cache entries matching all given tags ($tags can be an array of strings or a single string) 'notMatchingTag' => remove cache entries not matching one of the given tags ($tags can be an array of strings or a single string)

- return: true if no problem
- access: public

boolean clean ([string $mode = Zend_Cache::CLEANING_MODE_ALL], [tags $tags = array()])

- string $mode: clean mode
- tags $tags: array $tags array of tags

Implementation of:

Zend_Cache_Backend_Interface::clean()
  Clean some cache records

load (line 70)

Test if a cache is available for the given id and (if yes) return it (false else)

WARNING $doNotTestCacheValidity=true is unsupported by the APC backend

- return: cached datas (or false)
- access: public

string load (string $id, [boolean $doNotTestCacheValidity = false])

- string $id: cache id
- boolean $doNotTestCacheValidity: if set to true, the cache validity won't be tested

Implementation of:

Zend_Cache_Backend_Interface::load()
  Test if a cache is available for the given id and (if yes) return it (false else)

remove (line 129)

Remove a cache record

- return: true if no problem
- access: public

boolean remove (string $id)

- string $id: cache id

Implementation of:

Zend_Cache_Backend_Interface::remove()

save (line 111)

Save some string datas into a cache record

Note : $data is always "string" (serialization is done by the core not by the backend)

- return: true if no problem
- access: public

boolean save (string $data, string $id, [array $tags = array()], [int $specificLifeTime = false])

- string $data: datas to cache
- string $id: cache id
- array $tags: array of strings, the cache record will be tagged by each string entry
- int $specificLifeTime: if != false, set a specific lifetime for this cache record (null => infinite lifeTime)

Implementation of:

Zend_Cache_Backend_Interface::save()
  Save some string datas into a cache record

test (line 90)

Test if a cache is available or not (for the given id)

- return: false (a cache is not available) or "last modified" timestamp (int) of the available cache record
- access: public

mixed test (string $id)

- string $id: cache id

Implementation of:

Zend_Cache_Backend_Interface::test()
  Test if a cache is available or not (for the given id)
