Class MapSessionFactoryLookup

java.lang.Object

org.springframework.data.cassandra.core.cql.session.lookup.MapSessionFactoryLookup

All Implemented Interfaces:

SessionFactoryLookup

public class MapSessionFactoryLookup
extends Object
implements SessionFactoryLookup

Simple SessionFactoryLookup implementation that relies on a map for doing lookups.

Useful for testing environments or applications that need to match arbitrary String names to target SessionFactory objects. This class is not thread-safe for modifications. Once initialized, it can be shared amongst multiple threads and is thread-safe for reading.

Since:

2.0

Constructor Detail

MapSessionFactoryLookup

public MapSessionFactoryLookup()

Create a new instance of MapSessionFactoryLookup.

MapSessionFactoryLookup

public MapSessionFactoryLookup(Map<String,SessionFactory> sessionFactories)

Create a new instance of MapSessionFactoryLookup.

Parameters:

sessionFactories - the Map of session factories. The keys are Strings, the values are actual SessionFactory instances.

MapSessionFactoryLookup

public MapSessionFactoryLookup(String sessionFactoryName,
                               SessionFactory sessionFactory)

Create a new instance of MapSessionFactoryLookup.

Parameters:

sessionFactoryName - the name under which the supplied SessionFactory is to be added

sessionFactory - the SessionFactory to be added

Method Detail

setSessionFactories

public void setSessionFactories(@Nullable
                                Map<String,SessionFactory> sessionFactories)

Set the Map of session factories; the keys are Strings, the values are actual SessionFactory instances.

If the supplied Map is null, then this method call effectively has no effect.

Parameters:

sessionFactories - Map of session factories.

getSessionFactories

public Map<String,SessionFactory> getSessionFactories()

Get the Map of session factories maintained by this object.

The returned Map is unmodifiable.

Returns:

Map of session factories.

addSessionFactory

public void addSessionFactory(String sessionFactoryName,
                              SessionFactory sessionFactory)

Add the supplied SessionFactory to the map of session factories maintained by this object.

Parameters:

sessionFactoryName - the name under which the supplied SessionFactory is to be added

sessionFactory - the SessionFactory to be so added

getSessionFactory

public SessionFactory getSessionFactory(String sessionFactoryName)
                                 throws SessionFactoryLookupFailureException

Description copied from interface: SessionFactoryLookup

Implementations must implement this method to retrieve the SessionFactory identified by the given name from their backing store.

Specified by:

getSessionFactory in interface SessionFactoryLookup

Parameters:

sessionFactoryName - the name of the SessionFactory.

Returns:

the SessionFactory (never null).

Throws:

SessionFactoryLookupFailureException - if the lookup failed.
