Annotation Type LoadBalancerResource

@Documented
 @Retention(value=RUNTIME)
 @Target(value={METHOD,FIELD})
public @interface LoadBalancerResource

Annotates a field or a setter method for injection of ComputeLoadBalancer. Specific implementation for grid load balancer is defined by LoadBalancingSpi which is provided to grid via IgniteConfiguration..

Load balancer can be injected into instances of following classes:

• ComputeTask

Here is how injection would typically happen:

 public class MyGridTask extends ComputeTask<String, Integer> {
    @LoadBalancerResource
    private ComputeLoadBalancer balancer;
 }
 

or

 public class MyGridTask extends ComputeTask<String, Integer> {
     ...
     private ComputeLoadBalancer balancer;
     ...
     @LoadBalancerResource
     public void setBalancer(ComputeLoadBalancer balancer) {
         this.balancer = balancer;
     }
     ...
 }
 

See IgniteConfiguration.getLoadBalancingSpi() for Grid configuration details.
