Interface DeploymentNodeSelector

public interface DeploymentNodeSelector

A selector which selects and returns a node, from among the passed eligible nodes, that can handle a specific deployment within a EJB client context. Typical usage of DeploymentNodeSelector involves load balancing calls to multiple nodes which can all handle the same deployment. This allows the application to have a deterministic node selection policy while dealing with multiple nodes with same deployment.
