Examples of org.neo4j.graphdb.PropertyContainer

org.neo4j.graphdb.PropertyContainer
Defines a common API for handling properties on both {@link Node nodes} and{@link Relationship relationships}.
Properties are key-value pairs. The keys are always strings. Valid property value types are all the Java primitives (int, byte, float, etc), java.lang.Strings and arrays of primitives and Strings.
Please note that Neo4j does NOT accept arbitrary objects as property values. {@link #setProperty(String,Object) setProperty()} takes ajava.lang.Object only to avoid an explosion of overloaded setProperty() methods.
