Simple properties

Gaffer supports the storage of some common Java objects as properties on entities and edges. These include Integer, Long, Double, Float, Boolean, Date, String, byte[] and TreeSet. Serialisers for these will automatically be added to your schema when you create a graph using a schema that uses these properties. Aggregators for these properties are provided by the Koryphe library and include all the standard functions such as minimum, maximum, sum, etc.

Gaffer also provides a FreqMap property. This is a map from string to long.

The Getting started documentation includes examples of how to use these properties.
