Class GridXstreamMarshaller

java.lang.Object
  org.gridgain.grid.marshaller.xstream.GridXstreamMarshaller

All Implemented Interfaces:

GridMarshaller

public class GridXstreamMarshaller
extends Object
implements GridMarshaller

Implementation of GridMarshaller based on XStream. This marshaller does not require objects to implement Serializable.

Configuration

Mandatory

This marshaller has no mandatory configuration parameters.

Java Example

GridXstreamMarshaller has to be explicitly configured to override default GridOptimizedMarshaller.

 GridXstreamMarshaller marshaller = new GridXstreamMarshaller();

 GridConfigurationAdapter cfg = new GridConfigurationAdapter();

 // Override marshaller.
 cfg.setMarshaller(marshaller);

 // Starts grid.
 G.start(cfg);
 

Spring Example

GridXstreamMarshaller can be configured from Spring XML configuration file:

 <bean id="grid.custom.cfg" class="org.gridgain.grid.GridConfigurationAdapter" singleton="true">
     ...
     <property name="marshaller">
         <bean class="org.gridgain.grid.marshaller.xstream.GridXstreamMarshaller"/>
     </property>
     ...
 </bean>

Injection Example

GridXstreamMarshaller can be injected in users task, job or SPI as following:

 public class MyGridJob implements GridJob {
     ...
     @GridMarshallerResource
     private GridMarshaller marshaller;
     ...
 }
 

or

 public class MyGridJob implements GridJob {
     ...
     private GridMarshaller marshaller;
     ...
     @GridMarshallerResource
     public void setMarshaller(GridMarshaller marshaller) {
         this.marshaller = marshaller;
     }
     ...
 }
