Overview
The Rifid Edge Server Core is comprised of several modules that provide base functionality for developers to extend to meet the needs of their own applications and to access the data in an extensible way. The following links will provide more detail about a few important components in the edge server core.
- Configuration Framework
- The Configuration Framework handles persisting certain services, exposing them via JMX, and making them available in the OSGi registry
- Reader Framework
- The Reader Framework uses the Configuration Framework to expose readers as services to the rest of the edge server
- Command Framework
- The Command Framework uses the Configuration Framework to expose commands as services to the rest of the edge server
- RMI Interface
- The interface for programmatically interacting with the Edge Server
Architecture Overview
- ReaderFactory
- OSGi Service that produces Readers. Produces only one type of reader (i.e. Alien9800 reader).
- Reader
- A configured Reader Client. One-to-one relationship with a physical reader. Produces sessions. OSGi Service
- Session
- An active connection to a physical reader. Executor for Commands.
- CommandConfigurationFactory
- OSGi Service that produces CommandConfigurations. Can produce more than one type of CommandConfiguration (i.e. GetTagListCommand, GPIOEnabledCommand).
- CommandConfiguration
- A configured Command Factory. Produces configured commands of a certain type. OSGi Service.
- Command
- A runnable that is executed on a session. Must finish quickly.
