Method Details

addPluralSubgraph

default <AJ> SubGraph<AJ> addPluralSubgraph(PluralAttribute<? extends J,?,AJ> attribute)

Add a subgraph rooted at a plural attribute, allowing further nodes to be added to the subgraph.

Since:

6.3

getGraphedType

ManagedDomainType<J> getGraphedType()

Graphs apply only to ManagedTypes.

Returns:

the ManagedType being graphed here.

makeRootGraph

RootGraph<J> makeRootGraph(String name,
 boolean mutable)
                    throws CannotBecomeEntityGraphException

Create a named root Graph if the given name is not null.

Parameters:

mutable - controls whether the resulting Graph is mutable

Throws:

CannotBecomeEntityGraphException - If the named attribute is not entity-valued

makeSubGraph

SubGraph<J> makeSubGraph(boolean mutable)

Create a new (mutable or immutable) SubGraph rooted at this Graph.

makeCopy

Graph<J> makeCopy(boolean mutable)

Specified by:

makeCopy in interface GraphNode<J>

getGraphAttributeNodes

List<AttributeNode<?>> getGraphAttributeNodes()

Ultimately only needed for implementing EntityGraph.getAttributeNodes() and Subgraph.getAttributeNodes()

findAttributeNode

<AJ> AttributeNode<AJ> findAttributeNode(String attributeName)

Find an already existing AttributeNode by attributeName within this container

findAttributeNode

<AJ> AttributeNode<AJ> findAttributeNode(PersistentAttribute<? extends J,AJ> attribute)

Find an already existing AttributeNode by corresponding attribute reference, within this container.
