Overview

OpenSpaces provides a set of built-in components (plain beans with Spring integration) that simplify the development of OpenSpaces Processing Units.

The components are separated into several modules. The core components include basic infrastructure support such as Space construction, simplified API using the GigaSpace interface including Transaction Manager and declarative transaction support. Core components also include support for Map/Cache construction and a simplified API using GigaMap.

The events module includes components for simplified EDA/Service Bus development. These components allow unified event-handling and provide two mechanisms for event-generation: a polling container uses polling received operations against the space, and a notify container which uses the space's built-in notification support.

On top of the core components and the events components, OpenSpaces implements remoting, using the space as the transport layer, similar to other Spring remoting components.

Section Contents

• OpenSpaces Core Components
  • Applies To
  • OpenSpaces Core Component - GigaMap — The IMap/JCache Cache API is abstracted in OpenSpaces by a simple wrapper: the GigaMap interface.
  • OpenSpaces Core Component - GigaSpace — The JavaSpaces API is abstracted in OpenSpaces by a simple wrapper: the GigaSpace interface.
  • OpenSpaces Core Component - GigaSpace Context — Allows you to inject a predefined GigaSpace instance using annotations.
  • OpenSpaces Core Component - Local Cache and Local View — OpenSpaces allows you to easily configure and use the space local view feature using the LocalViewSpaceFactoryBean component and local cache using LocalCacheSpaceFactoryBean.
  • OpenSpaces Core Component - Map — A Map component allows you to create an IMap (or JCache Cache) based on a Space component.
  • OpenSpaces Core Component - Space — A Space component allows you to create an IJSpace (or JavaSpace) based on a space URL.
  • OpenSpaces Core Component - Space Mode Context Loader — Allows you to load a Spring application context only when the Processing Unit or space is in primary mode, and unload it when the Processing Unit or space is in backup mode.
  • OpenSpaces Core Component - Transaction Manager — OpenSpaces provides several implementations of Spring's PlatformTransactionManager allowing you to use the GigaSpaces and Jini Transaction Manager.
• OpenSpaces Events Components
  • OpenSpaces Events Component - Data Event Listener — Describe the common Space Data Event Listener and its different adapters.
  • OpenSpaces Events Component - Notify Container — The notify event container uses the space inheritance support for notifications, using GigaSpaces unified event session API.
  • OpenSpaces Events Component - Polling Container — Allows you to perform polling receive operations against the space.
• OpenSpaces Remoting Components — Remoting allows you to use remote invocations of POJO services, with the space as the transport layer.
  • OpenSpaces Remoting Component - Async Remoting — Async Remoting allows you to use remote invocations of POJO services, with the space as the transport layer.
  • OpenSpaces Remoting Component - Sync Remoting — Sync Remoting allows you to use remote invocations of POJO services, with the space as the transport layer.
