Class IgniteReflectionFactory<T>

java.lang.Object

org.apache.ignite.configuration.IgniteReflectionFactory<T>

All Implemented Interfaces:

Serializable, javax.cache.configuration.Factory<T>

public class IgniteReflectionFactory<T>
extends Object
implements javax.cache.configuration.Factory<T>

Factory implementation that use reflection to create instance of given class.

There are 2 modes of factory: singleton and non-sigletton.

Class that should be created by IgniteReflectionFactory (component class) have to be public java POJO with public setters for field for which property injection will be used (see setProperties(Map)).

Configuration

Mandatory

The following configuration parameters are mandatory:

• Component class - class to be created (see setComponentClass(Class). It have to be public java POJO class with default constructor and public setters to be used by properties injection (see setProperties(Map))

Optional

The following configuration parameters are optional:

• Singleton mode (see setSingleton(boolean))
• Properties map (see setProperties(Map)
• With method (see setWithMethod(Object, String, Serializable)

Java Example

 Factory factory =
     new IgniteReflectionFactory(MyCacheStoreSessionListener.class);

 CacheConfiguration cc = new CacheConfiguration()
     .setCacheStoreSessionListenerFactories(factory);

 IgniteConfiguration cfg = new IgniteConfiguration()
     .setCacheConfiguration(cc);

 // Start grid.
 Ignition.start(cfg);
 

Spring Example

TcpDiscoverySpi can be configured from Spring XML configuration file:

 <bean id="grid.custom.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
     ...
     <property name="cacheConfiguration">
         <list>
             <bean class="org.apache.ignite.configuration.CacheConfiguration">
                 ...
                 <property name="cacheStoreSessionListenerFactories">
                     <list>
                         <bean class="org.apache.ignite.configuration.IgniteReflectionFactory">
                             <property name="componentClass" value="custom.project.MyCacheStoreSessionListener"/>
                         </bean>
                     </list>
                 </property>
                 ...
             </bean>
         </list>
     </property>
     ...
 </bean>
