com.tangosol.util.Base
com.tangosol.net.AbstractBackingMapManager
com.tangosol.net.DefaultConfigurableCacheFactory.Manager
All Implemented Interfaces:
BackingMapManager
Enclosing class:
DefaultConfigurableCacheFactory
public class DefaultConfigurableCacheFactory.Manager extends AbstractBackingMapManager
BackingMapManager implementation that uses the configuration XML to create the required backing maps and provides client access to those maps.

  • Field Details

    • m_mapBackingMap

      protected Map m_mapBackingMap
      The map of backing maps keyed by corresponding cache names.

    • m_mapBackingMapListeners

      protected Map m_mapBackingMapListeners
      The map of backing map listeners keyed by the corresponding backing map references.

  • Constructor Details

    • Manager

      public Manager()

  • Method Details

    • init

      public void init(BackingMapManagerContext context)
      Called by a CacheService to indicate to this manager that the manager is being associated with the CacheService. This method is called once immediately upon the startup of the CacheService, before any NamedCache objects are created by the CacheService.

      Important note: BackingMapManager cannot be associated with more then one instance of a CacheService. However, in a situation when a CacheService automatically restarts, it is possible that this manager instance is re-used by a newly created (restarted) CacheService calling this method once again providing a new context.

      Specified by:
      init in interface BackingMapManager
      Overrides:
      init in class AbstractBackingMapManager
      Parameters:
      context - the BackingMapManagerContext object for this BackingMapManager

    • instantiateBackingMap

      public Map instantiateBackingMap(String sName)
      Instantiate a [thread safe] Map that should be used by a CacheService to store cached values for a NamedCache with the specified name.

      If the contents of the Map can be modified by anything other than the CacheService itself (e.g. if the Map automatically expires its entries periodically or size-limits its contents), then the returned object must implement the ObservableMap interface.

      Parameters:
      sName - the name of the NamedCache for which this backing map is being created
      Returns:
      an object implementing the Map interface that will provide backing storage for the specified cache name

    • isBackingMapPersistent

      public boolean isBackingMapPersistent(String sName)
      Determine if the contents of the Map that is used by a CacheService to store cached values for a NamedCache with the specified name should be persisted.
      Parameters:
      sName - the name of the NamedCache
      Returns:
      true if the CacheService should persist the backing storage of the specified NamedCache

    • isBackingMapSlidingExpiry

      public boolean isBackingMapSlidingExpiry(String sName)
      Determine if the Map that is used by a CacheService to store cached values for a NamedCache with specified name enables the sliding expiry - the expiry delay being extended by the read operations.
      Parameters:
      sName - the name of the NamedCache
      Returns:
      true if the backing map of the specified NamedCache enables the sliding expiry

    • getStorageAccessAuthorizer

      public StorageAccessAuthorizer getStorageAccessAuthorizer(String sName)
      Determine the StorageAccessAuthorizer that is used by a CacheService to secure access to the NamedCache with the specified name.
      Parameters:
      sName - the name of the NamedCache
      Returns:
      the StorageAccessAuthorizer or null if the authorizer is not configured

    • releaseBackingMap

      public void releaseBackingMap(String sName, Map map)
      Release the specified Map that was created using the BackingMapManager.instantiateBackingMap(String) method. This method is invoked by the CacheService when the CacheService no longer requires the specified Map object.
      Specified by:
      releaseBackingMap in interface BackingMapManager
      Overrides:
      releaseBackingMap in class AbstractBackingMapManager
      Parameters:
      sName - the name of the NamedCache for which the specified Map object has acted as the backing map
      map - the Map object that is being released

    • getBackingMap

      public Map getBackingMap(String sName)
      Get the backing Map associated with a given cache.
      Parameters:
      sName - the cache name
      Returns:
      a Map associated with the specified name

    • setBackingMap

      protected void setBackingMap(String sName, Map map)
      Associate the specified backing Map with a given name.
      Parameters:
      sName - the cache name
      map - the backing map associated with the specified name

    • getCacheFactory

      public DefaultConfigurableCacheFactory getCacheFactory()
      Obtain the "container" DefaultConfigurableCacheFactory that created this manager and which this manager is bound to.
      Returns:
      the DefaultConfigurableCacheFactory that created this manager
