public interface PropertyKey
extends RelationType

PropertyKey is an extension of RelationType for properties. Each property in Titan has a key.

A property key defines the following characteristics of a property:

• Data Type: The data type of the value for a given property of this key
• Cardinality: The cardinality of the set of properties that may be associated with a single vertex through a particular key.
