Detailed Description

Caches are obtained from the create method on the CacheFactory#create class.

When a cache will no longer be used, it should be closed. Once it is closed 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() [1/2]

void apache::geode::client::Cache::close ( )

overridevirtual

Terminates this object cache and releases all the local resources.

After this cache is closed, any further method call on this cache or any region object will throw CacheClosedException, unless otherwise noted. If Cache instance created from Pool(pool is in multiuser mode), then it reset user related security data.

Exceptions

CacheClosedException,if the cache is already closed.

Implements apache::geode::client::RegionService.

◆ close() [2/2]

virtual void apache::geode::client::Cache::close ( bool keepalive )

virtual

Terminates this object cache and releases all the local resources.

After this cache is closed, any further method call on this cache or any region object will throw CacheClosedException, unless otherwise noted. If Cache instance created from Pool(pool is in multiuser mode), then it reset user related security data.

Parameters

keepalive whether to keep a durable client's queue alive

Exceptions

CacheClosedException,if the cache is already closed.

◆ createAuthenticatedView()

virtual AuthenticatedView apache::geode::client::Cache::createAuthenticatedView	(	const std::shared_ptr< Properties > &	userSecurityProperties,
		const std::string &	poolName
	)

virtual

Creates an authenticated cache using the given user security properties.

Multiple instances with different user properties can be created with a single client cache.

Application must use this instance to do operations, when multiuser-authentication is set to true.

See also: RegionService; PoolFactory::setMultiuserAuthentication(boolean)

Returns: the RegionService instance associated with a user and given properties.

Exceptions

UnsupportedOperationException when invoked with multiuser-authentication as false.

Parameters

userSecurityProperties	the security properties of a user.
poolName	the pool that the users should be authenticated against. Set if there are more than one Pool in Cache.

◆ createPdxInstanceFactory() [1/2]

PdxInstanceFactory apache::geode::client::Cache::createPdxInstanceFactory ( const std::string & className ) const

overridevirtual

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.

Exceptions

IllegalStateException if the className is nullptr or invalid.

Returns: the factory

Implements apache::geode::client::RegionService.

◆ createPdxInstanceFactory() [2/2]

PdxInstanceFactory apache::geode::client::Cache::createPdxInstanceFactory	(	const std::string &	className,
		bool	expectDomainClass
	)		const

overridevirtual

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.
expectDomainClass	Whether or not created PdxType represents a Java domain class.

Exceptions

IllegalStateException if the className is nullptr or invalid.

Returns: the factory

Implements apache::geode::client::RegionService.

◆ createRegionFactory()

virtual RegionFactory apache::geode::client::Cache::createRegionFactory ( RegionShortcut regionShortcut )

virtual

Returns the RegionFactory to create the region.

Before creating the Region, one can set region attributes using this instance.

Parameters

regionShortcut To create the region specific type,

See also: RegionShortcut

◆ getCacheTransactionManager()

virtual std::shared_ptr< CacheTransactionManager > apache::geode::client::Cache::getCacheTransactionManager ( ) const

virtual

Get the CacheTransactionManager instance for this Cache.

Returns: The CacheTransactionManager instance.

Exceptions

CacheClosedException if the cache is closed.

◆ getLogLevel()

LogLevel apache::geode::client::Cache::getLogLevel ( )

Returns the current log level.

Returns: the current log level.

◆ getName()

const std::string & apache::geode::client::Cache::getName ( ) const

overridevirtual

Returns the name of this cache.

Returns: the string name of this cache

Implements apache::geode::client::GeodeCache.

◆ getPdxIgnoreUnreadFields()

bool apache::geode::client::Cache::getPdxIgnoreUnreadFields ( ) const

overridevirtual

Returns whether Cache saves unread fields for Pdx types.

Implements apache::geode::client::GeodeCache.

◆ getPdxReadSerialized()

bool apache::geode::client::Cache::getPdxReadSerialized ( ) const

overridevirtual

Returns whether PdxInstance is preferred for PDX types instead of C++ object.

Implements apache::geode::client::GeodeCache.

◆ getQueryService() [1/2]

std::shared_ptr< QueryService > apache::geode::client::Cache::getQueryService ( )

overridevirtual

Gets the QueryService from which a new Query can be obtained.

Returns: A smart pointer to the QueryService.

Implements apache::geode::client::RegionService.

◆ getQueryService() [2/2]

virtual std::shared_ptr< QueryService > apache::geode::client::Cache::getQueryService ( const std::string & poolName ) const

virtual

Gets the QueryService from which a new Query can be obtained.

Parameters

poolName Pass poolname if pool is created from cache.xml or PoolManager

Returns: A smart pointer to the QueryService.

◆ getRegion()

std::shared_ptr< Region > apache::geode::client::Cache::getRegion ( const std::string & path ) const

overridevirtual

Look up a region with the full path from root.

If Pool attached with Region is in multiusersecure mode then don't use return instance of region as no credential are attached with this instance. Get region from RegionService instance of Cache.

See also: Cache::createAuthenticatedView(std::shared_ptr<Properties>).

Parameters

path	the region's name, such as `AuthRegion`.

Returns: region, or nullptr if no such region exists.

Implements apache::geode::client::RegionService.

◆ getTypeRegistry()

TypeRegistry & apache::geode::client::Cache::getTypeRegistry ( ) const

Returns the type registry that this cache was created with.

◆ initializeDeclarativeCache()

void apache::geode::client::Cache::initializeDeclarativeCache ( const std::string & cacheXml )

overridevirtual

Initializes the cache from an xml file.

Parameters

cacheXml Valid cache.xml file

Implements apache::geode::client::GeodeCache.

◆ isClosed()

bool apache::geode::client::Cache::isClosed ( ) const

overridevirtual

Indicates if this cache has been closed.

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

Returns: true, if this cache is closed; false, otherwise

Implements apache::geode::client::RegionService.

◆ readyForEvents()

virtual void apache::geode::client::Cache::readyForEvents ( )

virtual

Send the "client ready" message to the server from a durable client.

◆ rootRegions()

std::vector< std::shared_ptr< Region > > apache::geode::client::Cache::rootRegions ( ) const

overridevirtual

Returns a set of root regions in the cache.

This set is a snapshot and is not backed by the Cache. The vector passed in is cleared and the regions are added to it.

Implements apache::geode::client::RegionService.

◆ setLogLevel()

void apache::geode::client::Cache::setLogLevel ( LogLevel newLevel )

Changes the current log level to newLogLevel.
