Method Detail

getOrCreateEntityGraph

public EntityGraph getOrCreateEntityGraph(java.lang.Class<?> entityClass,
                                          boolean forWriter)

Description copied from interface: EntityGraphProvider

Get an entity graph for given class. New graph is created if no graph exists for given class.

Specified by:

getOrCreateEntityGraph in interface EntityGraphProvider

Parameters:

entityClass - entity class the graph should be created for.

forWriter - flag determining whether the graph should be created for writer/reader.

Returns:

an entity graph.

getOrCreateEmptyEntityGraph

public EntityGraph getOrCreateEmptyEntityGraph(java.lang.Class<?> entityClass,
                                               boolean forWriter)

Description copied from interface: EntityGraphProvider

Get an empty entity graph for given class. New graph is created if the stored one is not an empty entity graph or no graph exists for given class. This method overrides the graph created by EntityGraphProvider.getOrCreateEntityGraph(Class, boolean) method.

Specified by:

getOrCreateEmptyEntityGraph in interface EntityGraphProvider

Parameters:

entityClass - entity class the graph should be created for.

forWriter - flag determining whether the graph should be created for writer/reader.

Returns:

an empty entity graph.

asMap

public java.util.Map<java.lang.Class<?>,EntityGraph> asMap(boolean forWriter)

Return an unmodifiable map of entity graphs for reader/writer.

Parameters:

forWriter - flag determining whether the returned map should be for writer/reader.

Returns:

an unmodifiable map of entity graphs.

containsEntityGraph

public boolean containsEntityGraph(java.lang.Class<?> entityClass,
                                   boolean forWriter)

Description copied from interface: EntityGraphProvider

Determine whether an entity graph for given entity class has been created by this provider.

Specified by:

containsEntityGraph in interface EntityGraphProvider

Parameters:

entityClass - entity class for which the graph should be checked.

forWriter - flag determining whether the check should be in writer/reader graphs.

Returns:

true if the entity graph already exists, false otherwise.

createObjectGraph

public ObjectGraph createObjectGraph(java.lang.Class<?> entityClass,
                                     java.util.Set<java.lang.String> filteringScopes,
                                     boolean forWriter)

Description copied from interface: EntityGraphProvider

Create an ObjectGraph for given parameters. Every time this method is called a new instance of object graph is created.

Specified by:

createObjectGraph in interface EntityGraphProvider

Parameters:

entityClass - entity class which the object graph should be created for.

filteringScopes - entity-filtering scopes the graph should be created for.

forWriter - flag determining whether the graph should be created for writer/reader.

Returns:

an entity-filtering object graph instance.
