Method Detail

getFrom

Object getFrom()

Gets the "from" vertex for the edge to be added. If the "from" vertex was added as a Vertex, ID, GValue, or ConstantTraversal, it is returned as a ReferenceVertex. Otherwise, it is returned in Traversal form.

getTo

Object getTo()

Gets the "to" vertex for the edge to be added. If the "to" vertex was added as a Vertex, ID, GValue, or ConstantTraversal, it is returned as a ReferenceVertex. Otherwise, it is returned in Traversal form.

getFromWithGValue

default Object getFromWithGValue()

Gets the "from" vertex for the edge to be added. If the "from" vertex was added as a Vertex, ID, or ConstantTraversal, it is returned as a ReferenceVertex. If it was added as a GValue containing a Vertex or ID, the GValue is returned. Otherwise, it is returned in Traversal form.

getToWithGValue

default Object getToWithGValue()

Gets the "from" vertex for the edge to be added. If the "from" vertex was added as a Vertex, ID, or ConstantTraversal, it is returned as a ReferenceVertex. If it was added as a GValue containing a Vertex or ID, the GValue is returned. Otherwise, it is returned in Traversal form.

getAdjacentVertex

default Object getAdjacentVertex(Parameters parameters,
                                 String key)

getAdjacentVertex

default Vertex getAdjacentVertex(Parameters parameters,
                                 String key,
                                 Traverser.Admin<S> traverser,
                                 String edgeLabel)
