Constructor Detail

ModelGraph

public ModelGraph(com.tinkerpop.blueprints.KeyIndexableGraph baseGraph)

Constructs a new ModelGraph.

Parameters:

baseGraph - the base graph

Method Detail

getIdConverter

@Nonnull
public Converter<Id,Object> getIdConverter()

Returns the converter to use a primitive representation instead of a complete Id.

Returns:

the id converter

requiresUniqueLabels

public boolean requiresUniqueLabels()

Return true if the base graph requires unique labels and properties.

Returns:

true if the base graph requires unique labels and properties

getVertex

@Nonnull
public Optional<ElementVertex> getVertex(Id id)

Returns the vertex referenced by the provided id.

Parameters:

id - the identifier of the vertex to retrieve from the graph

Returns:

an Optional containing the vertex referenced by the provided identifier, or Optional.empty() when no such vertex exists

See Also:

IdGraph.getVertex(Object), Converter.convert(Object)

getOrCreateVertex

@Nonnull
public ElementVertex getOrCreateVertex(Id id)

Returns the vertex referenced by the provided id. If no such vertex exists, it will be created and added to the graph.

Parameters:

id - the identifier of the vertex to retrieve, or create, from the graph

Returns:

the vertex

See Also:

IdGraph.getVertex(Object), IdGraph.addVertex(Object), Converter.convert(Object)

removeVertex

public void removeVertex(com.tinkerpop.blueprints.Vertex vertex)

Specified by:

removeVertex in interface com.tinkerpop.blueprints.Graph

Overrides:

removeVertex in class IdGraph<ModelGraph>

getClassVertex

@Nonnull
public Optional<ClassVertex> getClassVertex(ClassBean bean)

Returns the meta-class vertex associated to the provided bean.

Parameters:

bean - the simple representation of the meta-class

Returns:

an Optional containing the meta-class vertex

getClassVertices

@Nonnull
public Stream<ClassVertex> getClassVertices(Set<ClassBean> beans)

Returns all meta-class vertices associated to the given beans.

Parameters:

beans - a set of simple representation of the meta-classes

Returns:

an iterable of meta-class vertices

updateIndex

protected void updateIndex(ClassVertex classVertex)

Updates the meta-classes index with the specified classVertex. If the index already contains the vertex then this method does nothing.

Parameters:

classVertex - the meta-class vertex to index

copyTo

public void copyTo(ModelGraph target)

Specified by:

copyTo in interface Copiable<ModelGraph>
