CMIS: ACL Capabilities


RepositoryCapabilities interface provides getAclCapability() method to check the level of support for ACLs by the repository.

Following are the possible values of ACL capability.
Value
Description
none
The repository does not support ACL services.
discover
The repository supports discovery of ACLs (getACL and other services).
manage
The repository supports discovery of ACLs AND applying ACLs (getACL and apply- ACL services).

Example
                  RepositoryInfo repoInfo = session.getRepositoryInfo();

                  CapabilityAcl aclCapability = repoInfo.getCapabilities().getAclCapability();
                 
                  if(aclCapability == null){
                           System.out.println("Repository do not provide any value");
                  }else if(CapabilityAcl.NONE == aclCapability){
                           System.out.println("The repository does not support ACL services.");
                  }else if(CapabilityAcl.DISCOVER == aclCapability){
                           System.out.println("The repository supports discovery of ACLs (getACL and other services)");
                  }else if(CapabilityAcl.MANAGE == aclCapability){
                           System.out.println("The repository supports discovery of ACLs AND applying ACLs (getACL and apply-ACL services).");
                  }else{
                           System.out.println("Service is not implemented by the repository");
                  }
