Detailed Description

A RegionService provides access to existing regions that exist in a Cache.

Regions can be obtained using Cache.GetRegion and queried using <see cref="Cache.GetQueryService/>. <remarks> Caches are obtained from methods on the <see cref="CacheFactory.Create"/> class. <para> When a cache will no longer be used, call <see cref="Cache.Close" />. Once it <see cref="Cache.IsClosed" /> any attempt to use it will cause a CacheClosedException to be thrown.

A cache can have multiple root regions, each with a different name.

Member Function Documentation

Close()

void Apache::Geode::Client::IRegionService::Close

(

)

Terminates this object cache and releases all the local resources.

If RegionService is created from Cache.CreateAuthenticatedView, then it clears user related security data.

After this cache is closed, any further method call on this cache or any region object will throw CacheClosedException, unless otherwise noted.

Exceptions

CacheClosedException

if the cache is already closed.

Implemented in Apache::Geode::Client::Cache.

CreatePdxInstanceFactory()

IPdxInstanceFactory ^ Apache::Geode::Client::IRegionService::CreatePdxInstanceFactory

(

String^

className

)

Returns a factory that can create a PdxInstance.

Parameters

className

the fully qualified class name that the PdxInstance will become when it is fully deserialized.

Returns

the factory

Implemented in Apache::Geode::Client::Cache.

GetQueryService()

Client::QueryService ^ Apache::Geode::Client::IRegionService::GetQueryService

(

)

Get a query service object to be able to query the cache.

Currently only works against the java server in native mode, and at least some endpoints must have been defined in some regions before actually firing a query.

Implemented in Apache::Geode::Client::Cache.

GetRegion()

template<class TKey , class TValue >

IRegion< TKey, TValue > ^ Apache::Geode::Client::IRegionService::GetRegion

(

String^

name

)

Returns an existing region given the full path from root, or null if no such region exists.

Parameters

name	the name of the region

Returns

the region

Implemented in Apache::Geode::Client::Cache.

RootRegions()

template<class TKey , class TValue >

array< IRegion< TKey, TValue >^> ^ Apache::Geode::Client::IRegionService::RootRegions

(

)

Returns an array of root regions in the cache.

This set is a snapshot and is not backed by the cache.

It is not supported when Cache is created from Pool.

Returns

array of regions

Implemented in Apache::Geode::Client::Cache.

Property Documentation

IsClosed

bool Apache::Geode::Client::IRegionService::IsClosed

get

True if this cache has been closed.

After a new cache object is created, this method returns false. After Close is called on this cache object, this method returns true.

Returns

true if this cache is closed, otherwise false
