GVBuffer

Description

A GVBuffer is a complex data structure used to carry information from one node to another along a flow.

GVBuffers have all the same shape, based on three primary components:

Platform fields: contains identifying information of the flow such as System, Service, ID...
Properties: contains a collection of <name, value> pairs that represent additional properties of the flow
Payload: contains the service current payload, that can be represented in several ways (JMS messages, byte array, String...)
