Package org.jnetstream.packet.templates Description

Templates package which allow easy packet building using initializers and templates. This package contains a set of packet templates and initializers that are distributed as core part of jNetStream. The user can easily add its own templates by using Packets.newPacket(Class<? extends PacketTemplate>) method which will cache the template.

Packet initializers

A packet initializer is an object implementing the PacketInitializer interface that knows how to export some content into the packet decoder's runtime environment. That content exported as properties and possibly existing or new namespace is then utilized by packet codec and NPL definitions to lookup certain initializer property values that are assigned as initial state of data fields within a packet's headers.

Packet templates

A PacketTemplate is a prebuit packet whos contents are efficiently copied to a new packet which can then be further customized. Instead of adding individual headers and providing all the initialization functions, you can use a template to use one of the prebuilt packets to initialize new packets. You then can further customize the packet with your own data. Packet templates rely on packet initializers to help them initialize the state of the template packet.
