Overview

Encapsulates a vertex-property complex value. The name of the property is stored in the owning Vertex. This object contains a simple property value and any meta-properties that go with it.

VertexProperty's are created when creating a Vertex object out of a graph query result hash. Access to meta-properties is done via the #properties attribute, but there is also a short-cut using array/hash dereference syntax:

Examples:

val = vp.properties['meta1']
# is the same as
val = vp['meta1']
