Method Detail

getCardinality

public VertexProperty.Cardinality getCardinality(String key)

Description copied from interface: Graph.Features.VertexFeatures

Gets the VertexProperty.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.

Specified by:

getCardinality in interface Graph.Features.VertexFeatures

supportsAddVertices

public boolean supportsAddVertices()

Description copied from interface: Graph.Features.VertexFeatures

Determines if a Vertex can be added to the Graph.

Specified by:

supportsAddVertices in interface Graph.Features.VertexFeatures

supportsRemoveVertices

public boolean supportsRemoveVertices()

Description copied from interface: Graph.Features.VertexFeatures

Determines if a Vertex can be removed from the Graph.

Specified by:

supportsRemoveVertices in interface Graph.Features.VertexFeatures

properties

public Graph.Features.VertexPropertyFeatures properties()

Description copied from interface: Graph.Features.VertexFeatures

Gets features related to "properties" on a Vertex.

Specified by:

properties in interface Graph.Features.VertexFeatures
