org.springframework.data.gemfire.dao.GemfireDaoSupport

All Implemented Interfaces:

InitializingBean

public abstract class GemfireDaoSupport
extends DaoSupport

Convenient super class for Pivotal GemFire Data Access Objects (DAO) implementing the Spring DaoSupport abstract class. Intended for use with GemfireTemplate. Requires a Pivotal 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 Pivotal GemFire Region reference is passed in. A custom GemfireTemplate instance can be used through overriding createGemfireTemplate.

GemfireOperations, GemfireTemplate, setRegion(org.apache.geode.cache.Region<?, ?>)

getGemfireTemplate

public final GemfireOperations getGemfireTemplate()

Returns the GemfireTemplate for this DAO, pre-initialized with the Region or set explicitly.

Returns:

an instance of the GemfireTemplate to perform data access operations on the Pivotal GemFire Cache Region.

GemfireOperations, GemfireTemplate

setRegion

public void setRegion(org.apache.geode.cache.Region<?,?> region)

Sets the Pivotal GemFire Cache Region to be used by this DAO. Will automatically create an instance of the GemfireTemplate for the given Region.

Parameters:

region - the Pivotal GemFire Cache Region upon which this DAO operates.

See Also:

Region, createGemfireTemplate(org.apache.geode.cache.Region)

createGemfireTemplate

protected GemfireTemplate createGemfireTemplate(org.apache.geode.cache.Region<?,?> region)

Creates an instance of the GemfireTemplate for the given Pivotal GemFire Cache Region.

Can be overridden in subclasses to provide a GemfireTemplate instance with different configuration, or even a custom GemfireTemplate subclass.

Parameters:

region - the Pivotal GemFire Cache Region for which the GemfireTemplate is created.

Returns:

a new GemfireTemplate instance configured with the given Pivotal GemFire Cache Region.
