public EntityGraphImpl<T> makeImmutableCopy(String name)

makeMutableCopy

public EntityGraphImpl<T> makeMutableCopy()

getEntityType

public EntityType<T> getEntityType()

getName

public String getName()

Description copied from interface: EntityGraph

Return the name of a named EntityGraph - an entity graph defined by means of the NamedEntityGraph annotation, XML descriptor element, or added by means of the addNamedEntityGraph method. Returns null if the EntityGraph is not a named EntityGraph.

Specified by:

getName in interface EntityGraph<T>

addAttributeNodes

public void addAttributeNodes(String... attributeNames)

Description copied from interface: EntityGraph

Add one or more attribute nodes to the entity graph.

Specified by:

addAttributeNodes in interface EntityGraph<T>

Overrides:

addAttributeNodes in class AbstractGraphNode<T>

Parameters:

attributeNames - name of the attribute

addAttributeNodes

public void addAttributeNodes(Attribute<T,?>... attributes)

Description copied from interface: EntityGraph

Add one or more attribute nodes to the entity graph.

Specified by:

addAttributeNodes in interface EntityGraph<T>

Overrides:

addAttributeNodes in class AbstractGraphNode<T>

Parameters:

attributes - attribute

addSubgraph

public <X> SubgraphImpl<X> addSubgraph(Attribute<T,X> attribute)

Description copied from interface: EntityGraph

Add a node to the graph that corresponds to a managed type. This allows for construction of multi-node entity graphs that include related managed types.

Specified by:

addSubgraph in interface EntityGraph<T>

Overrides:

addSubgraph in class AbstractGraphNode<T>

Parameters:

attribute - attribute

Returns:

subgraph for the attribute

addSubgraph

public <X> SubgraphImpl<? extends X> addSubgraph(Attribute<T,X> attribute,
                                                 Class<? extends X> type)

Description copied from interface: EntityGraph

Add a node to the graph that corresponds to a managed type with inheritance. This allows for multiple subclass subgraphs to be defined for this node of the entity graph. Subclass subgraphs will automatically include the specified attributes of superclass subgraphs

Specified by:

addSubgraph in interface EntityGraph<T>

Overrides:

addSubgraph in class AbstractGraphNode<T>

Parameters:

attribute - attribute

type - entity subclass

Returns:

subgraph for the attribute

addSubgraph

public <X> SubgraphImpl<X> addSubgraph(String attributeName)

Description copied from interface: EntityGraph

Add a node to the graph that corresponds to a managed type. This allows for construction of multi-node entity graphs that include related managed types.

Specified by:

addSubgraph in interface EntityGraph<T>

Overrides:

addSubgraph in class AbstractGraphNode<T>

Parameters:

attributeName - name of the attribute

Returns:

subgraph for the attribute

addSubgraph

public <X> SubgraphImpl<X> addSubgraph(String attributeName,
                                       Class<X> type)

Description copied from interface: EntityGraph

Add a node to the graph that corresponds to a managed type with inheritance. This allows for multiple subclass subgraphs to be defined for this node of the entity graph. Subclass subgraphs will automatically include the specified attributes of superclass subgraphs.

Specified by:

addSubgraph in interface EntityGraph<T>

Overrides:

addSubgraph in class AbstractGraphNode<T>

Parameters:

attributeName - name of the attribute

type - entity subclass

subgraph for the attribute

addKeySubgraph

public <X> SubgraphImpl<X> addKeySubgraph(Attribute<T,X> attribute)

Description copied from interface: EntityGraph

Add a node to the graph that corresponds to a map key that is a managed type. This allows for construction of multi-node entity graphs that include related managed types. Use of this method implicitly adds the corresponding attribute node to the graph.

Specified by:

addKeySubgraph in interface EntityGraph<T>

Overrides:

addKeySubgraph in class AbstractGraphNode<T>

Parameters:

attribute - attribute

Returns:

subgraph for the key attribute

Specified by:

addKeySubgraph in interface EntityGraph<T>

Overrides:

addKeySubgraph in class AbstractGraphNode<T>
