public interface Marshaller
Marshaller
allows to marshal or unmarshal objects in grid. It provides
serialization/deserialization mechanism for all instances that are sent across networks
or are otherwise serialized.
Ignite provides the following Marshaller
implementations:
IgniteBinary
.JdkMarshaller
Below are examples of marshaller configuration, usage, and injection into tasks, jobs, and SPI's.
Marshaller
can be explicitly configured in code.
JdkMarshaller marshaller = new JdkMarshaller(); IgniteConfiguration cfg = new IgniteConfiguration(); // Override marshaller. cfg.setMarshaller(marshaller); // Starts grid. G.start(cfg);
<bean id="grid.custom.cfg" class="org.apache.ignite.configuration.IgniteConfiguration" singleton="true"> ... <property name="marshaller"> <bean class="org.apache.ignite.marshaller.jdk.JdkMarshaller"/> </property> ... </bean>
