| <section><p>Cache storage convenience adapter. It provides default implementation for |
| bulk operations, such as <code>LoadAll</code>, <code>PutAll</code> and |
| <code>RemoveAll</code> by sequentially calling corresponding <code>Load</code>, |
| <code>Put</code> and <code>Remove</code> operations. Use this adapter whenever |
| such behaviour is acceptable. However in many cases it maybe more preferable |
| to take advantage of database batch update functionality, and therefore default |
| adapter implementation may not be the best option. |
| <p> |
| Note that <code>LoadCache</code> method has empty implementation because it is |
| essentially up to the user to invoke it with specific arguments.</p> |

|
| <section><p>API for cache persistent storage for read-through and write-through behavior. |
| <p> |
| Generic argument types depend on <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.CacheConfiguration.html#Apache_Ignite_Core_Cache_Configuration_CacheConfiguration_KeepBinaryInStore">KeepBinaryInStore</a> property. |
| When <code>true</code> (default), cache store operates on <a class="xref" href="Apache.Ignite.Core.Binary.IBinaryObject.html">IBinaryObject</a> instances. |
| Otherwise, generic arguments should be the same as in corresponding <a class="xref" href="Apache.Ignite.Core.Cache.ICache-2.html">ICache<TK, TV></a>. |
| <p> |
| Persistent store is configured in Ignite's Spring XML configuration file via |
| <code>CacheConfiguration.setStore()</code> property. If you have an implementation |
| of cache store in .NET, you should use special Java wrapper which accepts assembly name and |
| class name of .NET store implementation (both properties are mandatory).</p> |
| <p>Optionally, you may specify "properies" property to set any property values on an instance of your store. |
| <example> |
| Here is an example:<p> |
| <pre><code><bean class="org.apache.ignite.configuration.CacheConfiguration"> |
| ... |
| <property name="cacheStoreFactory"> |
| <bean class="org.apache.ignite.platform.dotnet.PlatformDotNetCacheStoreFactory"> |
| <property name="assemblyName" value="MyAssembly"/> |
| <property name="className" value="MyApp.MyCacheStore"/> |
| <property name="properties"> |
| <map> |
| <entry key="IntProperty"> |
| <value type="java.lang.Integer">42</value> |
| </entry> |
| <entry key="StringProperty" value="String value"/> |
| </map> |
| </property> |
| </bean> |
| </property> |
| ... |
| </bean></code></pre> |
| <p></example> |
| Assemply name and class name are passed to <a target="_blank" href="http://msdn.microsoft.com/en-us/library/d133hta4.aspx"><strong>System.Activator.CreateInstance(String, String)</strong></a> |
| method during node startup to create an instance of cache store. Refer to its documentation for details. |
| <p> |
| All transactional operations of this API are provided with ongoing <a class="xref" href="Apache.Ignite.Core.Transactions.ITransaction.html">ITransaction</a>, |
| if any. You can attach any metadata to transaction, e.g. to recognize if several operations |
| belong to the same transaction or not. |
| <example> |
| Here is an example of how attach a ODBC connection as transaction metadata:<p> |
| <pre><code>OdbcConnection conn = tx.Meta("some.name"); |
| |
| if (conn == null) |
| { |
| conn = ...; // Create or get connection. |
| |
| // Store connection in transaction metadata, so it can be accessed |
| // for other operations on the same transaction. |
| tx.AddMeta("some.name", conn); |
| }</code></pre> |
| <p></example></p> |

| <h4><a class="xref" href="Apache.Ignite.Core.Cache.Store.ICacheStoreSession.html">ICacheStoreSession</a></h4>
|
| <section><p>Session for the cache store operations. The main purpose of cache store session |
| is to hold context between multiple store invocations whenever in transaction. For example, |
| you can save current database connection in the session <a class="xref" href="Apache.Ignite.Core.Cache.Store.ICacheStoreSession.html#Apache_Ignite_Core_Cache_Store_ICacheStoreSession_Properties">Properties</a> map. You can then |
| commit this connection in the <a class="xref" href="Apache.Ignite.Core.Cache.Store.ICacheStore-2.html#Apache_Ignite_Core_Cache_Store_ICacheStore_2_SessionEnd_System_Boolean_">SessionEnd(Boolean)</a> method.</p> |
