All Implemented Interfaces:

InitializingBean

public abstract class GemfireDaoSupport
extends DaoSupport

Convenient super class for GemFire Data Access Objects (DAO) implementing the Spring DaoSupport abstract class. Intended for use with GemfireTemplate. Requires a GemFire Region to be set, providing a GemfireTemplate based on it to subclasses. Can alternatively be initialized directly via a GemfireTemplate reusing the template's settings. This class will create its own GemfireTemplate if a GemFire Region reference is passed in. A custom GemfireTemplate instance can be used through overriding createGemfireTemplate.
