madmin/cache/manager/clear = DELETE FROM "madmin_cache"
  • Default:

count#

ansi#

Retrieves the records matched by the given criteria in the database

madmin/cache/manager/count/ansi =
  • Default:
  • Type: string - SQL statement for searching items
  • Since: 2014.03

Fetches the records matched by the given criteria from the cache database. The records must be from the sites that is configured in the context item.

To limit the records matched, conditions can be added to the given criteria object. It can contain comparisons like column names that must match specific values which can be combined by AND, OR or NOT operators. The resulting string of SQL conditions replaces the ":cond" placeholder before the statement is sent to the database server.

Contrary to the "search" statement, it doesn't return any records but instead the number of records that have been found. As counting thousands of records can be a long running task, the maximum number of counted records is limited for performance reasons.

The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

decorators#

excludes#

Excludes decorators added by the "common" option from the cache manager

madmin/cache/manager/decorators/excludes = Array
(
)

  • Default: Array ( )

  • Type: array - List of decorator names

  • Since: 2014.03

Decorators extend the functionality of a class by adding new aspects (e.g. cache what is currently done), executing the methods of the underlying class only in certain conditions (e.g. only for cacheged in users) or modify what is returned to the caller.

This option allows you to remove a decorator added via "madmin/common/manager/decorators/default" before they are wrapped around the cache manager.

 madmin/cache/manager/decorators/excludes = array( 'decorator1' )

This would remove the decorator named "decorator1" from the list of common decorators ("\Aimeos\MShop\Common\Manager\Decorator*") added via "madmin/common/manager/decorators/default" for the cache manager.

global#

Adds a list of globally available decorators only to the cache manager

madmin/cache/manager/decorators/global = Array
(
)

  • Default: Array ( )

  • Type: array - List of decorator names

  • Since: 2014.03

Decorators extend the functionality of a class by adding new aspects (e.g. cache what is currently done), executing the methods of the underlying class only in certain conditions (e.g. only for cacheged in users) or modify what is returned to the caller.

This option allows you to wrap global decorators ("\Aimeos\MShop\Common\Manager\Decorator*") around the cache manager.

 madmin/cache/manager/decorators/global = array( 'decorator1' )

This would add the decorator named "decorator1" defined by "\Aimeos\MShop\Common\Manager\Decorator\Decorator1" only to the cache controller.

Decorators extend the functionality of a class by adding new aspects (e.g. cache what is currently done), executing the methods of the underlying class only in certain conditions (e.g. only for cacheged in users) or modify what is returned to the caller.

This option allows you to wrap local decorators ("\Aimeos\MShop\Common\Manager\Decorator*") around the cache manager.

 madmin/cache/manager/decorators/local = array( 'decorator2' )

This would add the decorator named "decorator2" defined by "\Aimeos\MShop\Common\Manager\Decorator\Decorator2" only to the cache controller.

    SELECT "tid" FROM "madmin_cache_tag" WHERE "tname" IN (?)

madmin/cache/manager/get = 
 SELECT "id", "value", "expire" FROM "madmin_cache"
 WHERE ( "expire" >= ? OR "expire" IS NULL ) AND "id" IN (?)
  • Default:

name#

Class name of the used cache manager implementation

madmin/cache/manager/name = Standard
  • Default: Standard
  • Type: string - Last part of the class name
  • Since: 2014.03

Each default manager can be replace by an alternative imlementation. To use this implementation, you have to set the last part of the class name as configuration value so the manager factory knows which class it has to instantiate.

For example, if the name of the default class is

 \Aimeos\MShop\Cache\Manager\Standard

and you want to replace it with your own version named

 \Aimeos\MShop\Cache\Manager\Mymanager

then you have to set the this configuration option:

 madmin/cache/manager/name = Mymanager

The value is the last part of your own class name and it's case sensitive, so take care that the configuration value is exactly named like the last part of the class name.

The allowed characters of the class name are A-Z, a-z and 0-9. No other characters are possible! You should always start the last part of the class name with an upper case character and continue only with lower case characters or numbers. Avoid chamel case names like "MyManager"!

ansi#

Retrieves the records matched by the given criteria in the database

madmin/cache/manager/search/ansi = 
 SELECT "id", "value", "expire"
 FROM "madmin_cache"
 WHERE :cond
 ORDER BY "id"
 OFFSET :start ROWS FETCH NEXT :size ROWS ONLY
  • Default: madmin/cache/manager/search
  • Type: string - SQL statement for searching items
  • Since: 2014.03

Fetches the records matched by the given criteria from the cache database. The records must be from the sites that is configured in the context item.

To limit the records matched, conditions can be added to the given criteria object. It can contain comparisons like column names that must match specific values which can be combined by AND, OR or NOT operators. The resulting string of SQL conditions replaces the ":cond" placeholder before the statement is sent to the database server.

The number of returned records can be limited and can start at any number between the begining and the end of the result set. For that the ":size" and ":start" placeholders are replaced by the corresponding values from the criteria object. The default values are 0 for the start and 100 for the size value.

The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

ansi#

Inserts the cache entry into the database

madmin/cache/manager/set/ansi =
  • Default:
  • Type: string - SQL statement for inserting a new cache entry
  • Since: 2014.03

The ID, value and expiration timestamp are inserted as new record into the cache database. Any existing record must be deleted before the new one can be inserted.

The SQL statement must be a string suitable for being used as prepared statement. It must include question marks for binding the values from the cache item to the statement before they are sent to the database server. The number of question marks must be the same as the number of columns listed in the INSERT statement. The order of the columns must correspond to the order in the set() method, so the correct values are bound to the columns.

The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

Inserts a new tag to an existing cache entry

  • Default:
  • Type: string - SQL statement for inserting a new tag to an existing cache entry
  • Since: 2014.03

The ID of the cache entry and the tag name are inserted as a new record into the cache database. Any existing tag record that conflicts with the new one must be deleted before it can be inserted.

The SQL statement must be a string suitable for being used as prepared statement. It must include question marks for binding the cache ID and tag name from the cache item to the statement before they are sent to the database server. The number of question marks must be the same as the number of columns listed in the INSERT statement. The order of the columns must correspond to the order in the save() method, so the correct values are bound to the columns.

submanagers#

List of manager names that can be instantiated by the cache manager

madmin/cache/manager/submanagers = Array
(
)

  • Default: Array ( )

  • Type: array - List of sub-manager names

  • Since: 2014.03

Managers provide a generic interface to the underlying storage. Each manager has or can have sub-managers caring about particular aspects. Each of these sub-managers can be instantiated by its parent manager using the getSubManager() method.

The search keys from sub-managers can be normally used in the manager as well. It allows you to search for items of the manager using the search keys of the sub-managers to further limit the retrieved list of items.
