      • defineConfiguration

        Configuration defineConfiguration​(String cacheName,
                                  Configuration configuration)
        Register a cache configuration in the cache manager.

        The configuration will be automatically used when creating a cache with the same name, unless it is a template. If it is a template and it contains wildcards (`*` or `?`), it will be automatically used when creating caches that match the template.

        In order to extend an existing configuration, use ConfigurationBuilder.read(org.infinispan.configuration.cache.Configuration).

        The other way to define a cache configuration is declaratively, in the XML file passed in to the cache manager.

        Parameters:
        cacheName - name of the cache configuration
        configuration - the cache configuration
        Returns:
        the cache configuration
        Throws:
        CacheConfigurationException - if a configuration with the same name already exists.

      • defineConfiguration

        Configuration defineConfiguration​(String cacheName,
                                  String templateCacheName,
                                  Configuration configurationOverride)
        Defines a cache configuration by first reading the template configuration and then applying the override.

        The configuration will be automatically used when creating a cache with the same name, unless it is a template. If it is a template and it contains wildcards (`*` or `?`), it will be automatically used when creating caches that match the template.

        The other way to define a cache configuration is declaratively, in the XML file passed in to the cache manager.

        If templateName is null, this method works exactly like defineConfiguration(String, Configuration).

        Parameters:
        cacheName - name of cache whose configuration is being defined
        templateCacheName - configuration to use as a template
        configurationOverride - configuration overrides on top of the template
        Returns:
        the configuration
        Throws:
        CacheConfigurationException - if a configuration with the same name already exists.

      • undefineConfiguration

        void undefineConfiguration​(String configurationName)
        Removes a configuration from the set of defined configurations.

        If the named configuration does not exist, nothing happens.

        Parameters:
        configurationName - the named configuration
        Throws:
        IllegalStateException - if the configuration is in use

      • getClusterName

        String getClusterName()
        Returns:
        the name of the cluster. Null if running in local mode.

      • getMembers

        List<org.infinispan.remoting.transport.Address> getMembers()
        Returns:
        the addresses of all the members in the cluster, or null if not connected

      • getAddress

        org.infinispan.remoting.transport.Address getAddress()
        Warning: the address may be null before the first clustered cache starts and after all the clustered caches have been stopped.
        Returns:
        the address of the local node, or null if not connected

      • getCoordinator

        org.infinispan.remoting.transport.Address getCoordinator()
        Returns:
        the address of the cluster's coordinator, or null if not connected

        boolean isCoordinator()
        Returns:
        whether the local node is the cluster's coordinator, or null if not connected

        the global configuration object associated to this CacheManager

      • getCacheConfiguration

        Configuration getCacheConfiguration​(String name)
        Returns the configuration for the given cache.
        Returns:
        the configuration for the given cache or null if no such cache is defined

      • getDefaultCacheConfiguration

        Configuration getDefaultCacheConfiguration()
        Returns:
        the default cache's configuration, or null if there is no default cache.

      • getCacheConfigurationNames

        default Set<String> getCacheConfigurationNames()
        This method returns a collection of all cache configuration names.

        The configurations may have been defined via XML, programmatically via ConfigurationBuilderHolder, or at runtime via defineConfiguration(String, Configuration).

        Internal caches defined via InternalCacheRegistry are not included.

        Returns:
        an immutable set of configuration names registered in this cache manager.
        Since:
        8.2

      • isRunning

        boolean isRunning​(String cacheName)
        Tests whether a cache is running.
        Parameters:
        cacheName - name of cache to test.
        Returns:
        true if the cache exists and is running; false otherwise.

      • isDefaultRunning

        boolean isDefaultRunning()
        Tests whether the default cache is running.
        Returns:
        true if the default cache is running; false otherwise.

      • cacheExists

        boolean cacheExists​(String cacheName)
        A cache is considered to exist if it has been created and started via one of the getCache() methods and has not yet been removed via removeCache(String).

        In environments when caches are continuously created and removed, this method offers the possibility to find out whether a cache has either, not been started, or if it was started, whether it's been removed already or not.
        Parameters:
        cacheName - cache to check
        Returns:
        true if the cache with the given name has not yet been started, or if it was started, whether it's been removed or not.

      • getCache

        <K,​V> Cache<K,​V> getCache​(String cacheName)
        Retrieves a cache by name.

        If the cache has been previously created with the same name, the running cache instance is returned. Otherwise, this method attempts to create the cache first.

        When creating a new cache, this method requires a defined configuration that either has exactly the same name, or is a template with wildcards and matches the cache name.

        Specified by:
        getCache in interface BasicCacheContainer
        Specified by:
        getCache in interface CacheContainer
        Parameters:
        cacheName - name of cache to retrieve
        Returns:
        a cache instance identified by cacheName

      • createCache

        <K,​V> Cache<K,​V> createCache​(String name,
                                         Configuration configuration)
        Creates a cache on the local node using the supplied configuration.

        The cache may be clustered, but this method (or the equivalent combination of defineConfiguration(String, Configuration) and getCache(String, boolean)) needs to be invoked on all nodes.

        Type Parameters:
        K - the generic type of the key
        V - the generic type of the value
        Parameters:
        name - the name of the cache
        configuration - the configuration to use.
        Returns:
        the cache

      • getCache

        <K,​V> Cache<K,​V> getCache​(String cacheName,
                                      boolean createIfAbsent)
        Similar to getCache(String), except if has the option to not create the cache if it is not already running.
        Parameters:
        cacheName - name of cache to retrieve
        createIfAbsent - If true, this methods works just like getCache(String). If false, return the already running cache or null.
        Returns:
        null if the cache does not exist and createIfAbsent == false, otherwise a cache instance identified by cacheName

      • startCaches

        EmbeddedCacheManager startCaches​(String... cacheNames)
        Starts a set of caches in parallel. Infinispan supports both symmetric and asymmetric clusters; that is, multiple nodes having the same or different sets of caches running, respectively. Calling this method on application/application server startup with all your cache names will ensure that the cluster is symmetric.
        Parameters:
        cacheNames - the names of the caches to start
        Since:
        5.0

      • removeCache

        @Deprecated
void removeCache​(String cacheName)
        Deprecated.
        Since 9.2, obtain a CacheContainerAdmin instance using administration() and invoke the CacheContainerAdmin.removeCache(String) method
        Removes a cache with the given name from the system. This is a cluster wide operation that results not only in stopping the cache with the given name in all nodes in the cluster, but also deletes its contents both in memory and in any backing cache store.
        Parameters:
        cacheName - name of cache to remove

        void addCacheDependency​(String from,
                        String to)
        Add a dependency between two caches. The cache manager will make sure that a cache is stopped before any of its dependencies
        Parameters:
        from - cache name
        to - cache name
        Since:
        7.0

      • getStats

        @Deprecated
CacheContainerStats getStats()
        Deprecated.

        Returns:
        statistics for this cache manager
        Since:
        7.1

      • executor

        default ClusterExecutor executor()
        Providess the cache manager based executor. This can be used to execute a given operation upon the cluster or a single node if desired. If this manager is not clustered this will execute locally only.

        Note that not all EmbeddedCacheManager implementations may implement this. Those that don't will throw a UnsupportedOperationException upon invocation.

        Returns:

      • getHealth

        org.infinispan.health.Health getHealth()
        Returns an entry point for a Health Check API.
