Graph.Features.VertexFeaturesVertex can support properties on vertex properties. It is assumed that a
graph will support all the same data types for meta-properties that are supported for regular
properties.supportsMetaProperties in interface Graph.Features.VertexFeaturespublic boolean supportsMultiProperties()
Graph.Features.VertexFeaturesVertex can support multiple properties with the same key.supportsMultiProperties in interface Graph.Features.VertexFeaturespublic boolean supportsUserSuppliedIds()
Graph.Features.ElementFeaturesElement can have a user defined identifier. Implementations that do not support
this feature will be expected to auto-generate unique identifiers. In other words, if the Graph
allows graph.addVertex(id,x) to work and thus set the identifier of the newly added
Vertex to the value of x then this feature should return true. In this case, x
is assumed to be an identifier data type that the Graph will accept.supportsUserSuppliedIds in interface Graph.Features.ElementFeaturessupportsUserSuppliedIds in class Neo4jGraph.Neo4jGraphFeatures.Neo4jElementFeaturespublic VertexProperty.Cardinality getCardinality(String key)
Graph.Features.VertexFeaturesVertexProperty.Cardinality for a key. By default, this method will return
VertexProperty.Cardinality.list. Implementations that employ a schema can consult it to
determine the VertexProperty.Cardinality. Those that do no have a schema can return their
default VertexProperty.Cardinality for every key.
Note that this method is primarily used by TinkerPop for internal usage and may not be suitable to
reliably determine the cardinality of a key. For some implementation it may offer little more than a
hint on the actual cardinality. Generally speaking it is likely best to drop down to the API of the
Graph implementation for any schema related queries.getCardinality in interface Graph.Features.VertexFeaturesCopyright © 2013–2019 Apache Software Foundation. All rights reserved.
