Method Detail

makeEdgeLabel

public EdgeLabel makeEdgeLabel(EdgeLabelMaker factory)

Description copied from interface: DefaultSchemaMaker

Creates a new edge label with default settings against the provided EdgeLabelMaker.

Specified by:

makeEdgeLabel in interface DefaultSchemaMaker

Parameters:

factory - EdgeLabelMaker through which the edge label is created

Returns:

A new edge label

defaultPropertyCardinality

public Cardinality defaultPropertyCardinality(String key)

Specified by:

defaultPropertyCardinality in interface DefaultSchemaMaker

Returns:

the default cardinality of a property if created for the given key

makePropertyKey

public PropertyKey makePropertyKey(PropertyKeyMaker factory)

Description copied from interface: DefaultSchemaMaker

Creates a new property key with default settings against the provided PropertyKeyMaker.

Specified by:

makePropertyKey in interface DefaultSchemaMaker

Parameters:

factory - PropertyKeyMaker through which the property key is created

Returns:

A new property key

makeVertexLabel

public VertexLabel makeVertexLabel(VertexLabelMaker factory)

Description copied from interface: DefaultSchemaMaker

Creates a new vertex label with the default settings against the provided VertexLabelMaker.

Specified by:

makeVertexLabel in interface DefaultSchemaMaker

Parameters:

factory - VertexLabelMaker through which the vertex label is created

Returns:

A new vertex label

ignoreUndefinedQueryTypes

public boolean ignoreUndefinedQueryTypes()

Description copied from interface: DefaultSchemaMaker

Whether to ignore undefined types occurring in a query.

If this method returns true, then undefined types referred to in a JanusGraphVertexQuery will be silently ignored and an empty result set will be returned. If this method returns false, then usage of undefined types in queries results in an IllegalArgumentException.

Specified by:

ignoreUndefinedQueryTypes in interface DefaultSchemaMaker

makePropertyConstraintForEdge

public void makePropertyConstraintForEdge(EdgeLabel edgeLabel,
                                          PropertyKey key,
                                          SchemaManager manager)

Description copied from interface: DefaultSchemaMaker

Add property constraints for a given edge label using the schema manager.

Specified by:

makePropertyConstraintForEdge in interface DefaultSchemaMaker

Parameters:

edgeLabel - to which the constraint applies.

key - defines the property which should be added to the edge label as a constraint.

manager - is used to update the schema.

makePropertyConstraintForVertex

public void makePropertyConstraintForVertex(VertexLabel vertexLabel,
                                            PropertyKey key,
                                            SchemaManager manager)

Description copied from interface: DefaultSchemaMaker

Add property constraints for a given vertex label using the schema manager.

Specified by:

makePropertyConstraintForVertex in interface DefaultSchemaMaker

Parameters:

vertexLabel - to which the constraint applies.

key - defines the property which should be added to the vertex label as a constraint.

manager - is used to update the schema.

SchemaManager

makeConnectionConstraint

public void makeConnectionConstraint(EdgeLabel edgeLabel,
                                     VertexLabel outVLabel,
                                     VertexLabel inVLabel,
                                     SchemaManager manager)

Description copied from interface: DefaultSchemaMaker

Add a constraint on which vertices the given edge label can connect using the schema manager.

Specified by:

makeConnectionConstraint in interface DefaultSchemaMaker

Parameters:

edgeLabel - to which the constraint applies.

outVLabel - specifies the outgoing vertex for this connection.

inVLabel - specifies the incoming vertex for this connection.

manager - is used to update the schema.
