Reference server

This is a Java server that can easily be used to implement a back-end groups service for all of the above transports.  All you need to do is implement the service interfaces.  e.g.

Code Block

/**/**
 *
 */
package org.jasig.fifer.fiferServer.logic;

import org.jasig.fifer.fiferServer.coreapi.GroupHasMemberResponse;
import org.jasig.fifer.fiferServer.coreapi.GroupLookup;
import org.jasig.fifer.fiferServer.coreapi.SubjectLookup;
import org.jasig.fifer.fiferServer.group.MembershipImmediacy;


/**
 * Implement this interface to delegate the fifer logic calls
 * @author mchyzer
 *
 */
public interface FiferGroupLogicInterface {

  /**
   * see if a group has a member
   * @param groupLookup
   * @param subjectLookup
   * @param membershipImmediacy
   * @return the result
   */
  public GroupHasMemberResponse hasMember(GroupLookup groupLookup, SubjectLookup subjectLookup,
      MembershipImmediacy membershipImmediacy);

}

Here is an example of the Grouper implementation (translates the FIFER API to the Grouper client and back):

Code Block

package org.jasig.fifer.fiferServer.grouper;

import org.apache.commons.lang.StringUtils;
import org.jasig.fifer.fiferServer.coreapi.GroupHasMemberResponse;
import org.jasig.fifer.fiferServer.coreapi.GroupLookup;
import org.jasig.fifer.fiferServer.coreapi.ResponseMetadata;
import org.jasig.fifer.fiferServer.coreapi.SubjectLookup;
import org.jasig.fifer.fiferServer.group.MembershipImmediacy;
import org.jasig.fifer.fiferServer.logic.FiferGroupLogicInterface;

import edu.internet2.middleware.grouperClient.api.GcHasMember;
import edu.internet2.middleware.grouperClient.ws.WsMemberFilter;
import edu.internet2.middleware.grouperClient.ws.beans.WsHasMemberResults;
import edu.internet2.middleware.grouperClient.ws.beans.WsSubjectLookup;

/**
 * Implement the fifer group service for Grouper
 * @author mchyzer
 *
 */
public class GrouperGroupLogic implements FiferGroupLogicInterface {

  /**
   * convert from handle to group name
   * @param handle
   * @return the group name
   */
  private String convertFromGroupHandleToGroupName(String handle) {
    //TODO translate from handle to group name
    return handle;
  }

  /**
   * @see FiferGroupLogicInterface#hasMember(GroupLookup, SubjectLookup, MembershipImmediacy)
   */
  @Override
  public GroupHasMemberResponse hasMember(GroupLookup groupLookup, SubjectLookup subjectLookup,
      MembershipImmediacy membershipImmediacy) {

    GcHasMember gcHasMember = new GcHasMember();

    {
      if (!StringUtils.isBlank(groupLookup.getId())) {
        gcHasMember.assignGroupUuid(groupLookup.getId());
      }
      if (!StringUtils.isBlank(groupLookup.getHandle())) {
        gcHasMember.assignGroupName(convertFromGroupHandleToGroupName(groupLookup.getHandle()));
      }

    }

    {
      WsSubjectLookup wsSubjectLookup = new WsSubjectLookup();
      if (!StringUtils.isBlank(subjectLookup.getHandle())) {
        wsSubjectLookup.setSubjectIdentifier(subjectLookup.getHandle());
      }
      if (!StringUtils.isBlank(subjectLookup.getId())) {
        wsSubjectLookup.setSubjectId(subjectLookup.getId());
      }
      if (!StringUtils.isBlank(subjectLookup.getIdOrHandle())) {
        //set both of these for id or identifier
        wsSubjectLookup.setSubjectId(subjectLookup.getIdOrHandle());
        wsSubjectLookup.setSubjectIdentifier(subjectLookup.getIdOrHandle());
      }

    }

    {

      if (membershipImmediacy == MembershipImmediacy.any) {
        gcHasMember.assignMemberFilter(WsMemberFilter.All);
      }
      if (membershipImmediacy == MembershipImmediacy.immediate) {
        gcHasMember.assignMemberFilter(WsMemberFilter.Immediate);
      }
      if (membershipImmediacy == MembershipImmediacy.nonimmediate) {
        gcHasMember.assignMemberFilter(WsMemberFilter.NonImmediate);
      }
    }

    WsHasMemberResults wsHasMemberResults = gcHasMember.execute();

    GroupHasMemberResponse groupHasMemberResponse = new GroupHasMemberResponse();
    ResponseMetadata responseMetadata = new ResponseMetadata();
    groupHasMemberResponse.setResponseMetadata(responseMetadata);


    if (StringUtils.equals(wsHasMemberResults.getResultMetadata().getSuccess(), "T")
        || StringUtils.equals(wsHasMemberResults.getResultMetadata().getResultCode(), "SUBJECT_NOT_FOUND")) {
      responseMetadata.setSuccess(true);

      if (StringUtils.equals(wsHasMemberResults.getResultMetadata().getResultCode(), "SUBJECT_NOT_FOUND")
          || StringUtils.equals(wsHasMemberResults.getResultMetadata().getResultCode(), "IS_NOT_MEMBER")) {
        groupHasMemberResponse.setHasMember(false);
      } else if (StringUtils.equals(wsHasMemberResults.getResultMetadata().getResultCode(), "IS_MEMBER")) {
        groupHasMemberResponse.setHasMember(true);
      } else {
        throw new RuntimeException("Note expecting Grouper result code: " + wsHasMemberResults.getResultMetadata().getResultCode());
      }
    }
    return groupHasMemberResponse;

  }

}

Note, the service implementor only needs to worry about the current version of the FIFER API, the reference implementation will degrade gracefully to all previous versions of the API for all formats.
