All Implemented Interfaces:
BackingMapManager
Enclosing class:
ExtensibleConfigurableCacheFactory

public static class ExtensibleConfigurableCacheFactory.PartitionedBackingMapManager extends AbstractBackingMapManager
The PartitionedBackingMapManager is used by PartitionAwareBackingMap(s) to lazily configure the enclosing PABM based on the configuration settings of the enclosed maps.
  • Constructor Details

    • PartitionedBackingMapManager

      protected PartitionedBackingMapManager(ExtensibleConfigurableCacheFactory factory, MapBuilder.Dependencies dependencies, ParameterResolver resolver, MapBuilder bldrMap)
      Create a PartitionedBackingMapManager object.
      Parameters:
      factory - the factory associated with this manager
      dependencies - the MapBuilder dependencies
      resolver - the ParameterResolver needed to resolve cache params
      bldrMap - the builder that will build the backing map
  • Method Details

    • 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. NOTE: The cache name passed in has a partition number appended to it so that we cannot use it to find a parameter resolver. This is why the resolver is passed into the constructor.

      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
    • getCacheFactory

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