Class OraclePropertyBase<V>

java.lang.Object

oracle.pg.common.OraclePropertyBase<V>

Direct Known Subclasses:

OracleVertexPropertyBase

public class OraclePropertyBase<V>
extends java.lang.Object

This class implements the Property Tinkerpop3 interface for handling edge properties. A Property denotes a key/value pair associated with an Edge. A property is much like a Java8 Optional in that a property can be not present (i.e. empty). The key of a property is always a String and the value of a property is an arbitrary Java object. Each underlying graph engine will typically have constraints on what Java objects are allowed to be used as values.
