Constructor Detail

MemEngine

public MemEngine()

Creates a new MemEngine with the default application context. Each application context can have it's own set of global listeners. MemEngine instances constructed via this constructor will use the global graph cache.

MemEngine

public MemEngine(boolean useGlobalGraphCache)

Creates a new MemEngine with the default application context. Each application context can have it's own set of global listeners.

Parameters:

useGlobalGraphCache - Specifies whether this engine should use the global graph cache, or a cache specific to this instance.

MemEngine

public MemEngine(String applicationContext)

Creates a new MemEngine with the given application context. Each application context has it's own set of global listeners. This allows different applications running the same JVM to have different sets of listeners without having to add them at the process level. MemEngine instances constructed via this constructor will use the global graph cache.

Parameters:

applicationContext - The application context

MemEngine

public MemEngine(String applicationContext,
                 boolean useGlobalGraphCache)

Creates a new MemEngine with the given application context. Each application context has it's own set of global listeners. This allows different applications running the same JVM to have different sets of listeners without having to add them at the process level.

Parameters:

applicationContext - The application context

useGlobalGraphCache - Specifies whether this engine should use the global graph cache, or a cache specific to this instance.

MemEngine

public MemEngine(String applicationContext,
                 MemGraphRepository repository)

Creates a new MemEngine with the given application context. Each application context has it's own set of global listeners. This allows different applications running the same JVM to have different sets of listeners without having to add them at the process level.

Parameters:

applicationContext - The application context

repository - The repository to use for loading graphs and as a graph source

Method Detail

getFactory

public MemGraphFactory getFactory()

Description copied from interface: Engine

Returns an appropriate GraphFactory for this Engine. Subclasses may override this provide customer behavior.

Returns:

A GraphFactory which will generate the appropriate types for this Engine.

getRepository

public MemGraphRepository getRepository()

Description copied from interface: Engine

Returns an appropriate GraphRepository for this Engine. Subclasses may override this to provide custom behavior.

Returns:

An appropriate GraphRepository for this Engine

getLoader

public GraphLoader<MemGraph> getLoader()

Description copied from interface: Engine

Returns an appropriate GraphLoader for this Engine. Subclasses may override this provide customer behavior.

Equivalent to getLoader( null )

Returns:

A GraphLoader which, by default, will use the factory and repository from this engine.

getLoader

public GraphLoader<MemGraph> getLoader(GraphValidator validator)

Description copied from interface: Engine

Returns an appropriate GraphLoader for this Engine. Subclasses may override this provide customer behavior.

Returns:

A GraphLoader which, by default, will use the factory and repository from this engine.

newEngine

public MemEngine newEngine()

Description copied from class: BaseEngine

Creates a new engine base on the same parameters as this. For example, if the engine is database backed, it should share the same database engine.

Returns:

A new engine
