| <div class="block">Indexing SPI allows user to index cache content. Using indexing SPI user can index data in cache and run queries. |
| <p> |
| <b>NOTE:</b> this SPI (i.e. methods in this interface) should never be used directly. SPIs provide |
| internal view on the subsystem and is used internally by Ignite kernal. In rare use cases when |
| access to a specific implementation of this SPI is required - an instance of this SPI can be obtained |
| via <a href="../../../../../org/apache/ignite/Ignite.html#configuration--"><code>Ignite.configuration()</code></a> method to check its configuration properties or call other non-SPI |
| methods. Note again that calling methods from this interface on the obtained instance can lead |
| to undefined behavior and explicitly not supported. |
| |
| <b>NOTE:</b> Key and value arguments of IgniteSpi methods can be <a href="../../../../../org/apache/ignite/binary/BinaryObject.html" title="interface in org.apache.ignite.binary"><code>BinaryObject</code></a> instances. |
| BinaryObjects can be deserialized manually if original objects needed. |
| |
| Here is a Java example on how to configure SPI. |
| <pre name="code" class="java"> |
| IndexingSpi spi = new MyIndexingSpi(); |
| |
| IgniteConfiguration cfg = new IgniteConfiguration(); |
| |
| // Overrides default indexing SPI. |
| cfg.setIndexingSpi(spi); |
| |
| // Starts grid. |
| Ignition.start(cfg); |
| </pre> |
| Here is an example of how to configure SPI from Spring XML configuration file. |
| <pre name="code" class="xml"> |
| <property name="indexingSpi"> |
| <bean class="com.example.MyIndexingSpi"> |
