Interface PermissionProvider

public interface PermissionProvider
SPI for resolving agent permissions at runtime.

Used by SecurityEnforcer to evaluate Security.requiredPermissions(). When no provider is on the classpath, permission checks are skipped.

Implementing a Provider


 public class DefaultPermissionProvider implements PermissionProvider {

     public boolean hasPermission(String agentId, String permission) {
         return getPermissions(agentId).contains(permission);
     }

     public Set<String> getPermissions(String agentId) {
         // look up from config, database, etc.
     }
 }
