Class CommunityContext

    java.lang.Object
      com.bea.netuix.servlets.manager.communities.CommunityContext

    public final class CommunityContext

extends Object

The CommunityContext object serves as a cache container and accessor for community and membership information for a `HttpSession`. Each `CommunityContext` object instance has exactly one community in scope, in the form of a `CommunityDefinition` object. If the authenticated principal (logged-in user) for the `HttpRequest` has a membership in the community, the `CommunityContext` also contains the membership information in the form of a `CommunityMembership` object.

`CommunityContext`s can be accessed for the "default" community (the one associated with the `Desktop` currently being viewed, if any) but may also be retrieved for any `CommunityDefinition` within the webapp.

The caching scope used within a `CommunityContext` is controlled by the underlying `CommunityUserContext` object. There are cases where the cache can become stale; these are discussed along with remedies in the documentation for `CommunityUserContext`.

The overview of community functionality contains a description of the community framework.

Method Detail

### getCommunityContext

    public static CommunityContext getCommunityContext(javax.servlet.http.HttpServletRequest request)

  A convenience method for returning the "default" `CommunityContext` object associated with the specified Request. This is the `CommunityContext` appropriate for the Desktop viewed by the Request. This method should be called every time a `CommunityContext` is needed, and the returned value should never be cached or kept as a reference, since the context object maintains a reference to the request and will be invalid on subsequent requests. This method is optimized internally to only create a new context object once per request, so there is no performance benefit to maintaing references to the return value in any case.

  Parameters
    `request` - the `HttpServletRequest`.
  Returns
    the "default" (desktop-associated) `CommunityContext` object associated with the request, or `null` if the desktop associated with the request is not a community desktop.

### getCommunityContext

    public static CommunityContext getCommunityContext(javax.servlet.http.HttpServletRequest request,
                                                       CommunityURI communityUri)

  Returns the `CommunityContext` object associated with the specified request and community. This method should be called every time a `CommunityContext` is needed, and the returned value should never be cached or kept as a reference, since the context object maintains a reference to the request and will be invalid on subsequent requests. This method is optimized internally to only create a new context object once per request, so there is no performance benefit to maintaing references to the return value in any case.

  Parameters
    `request` - the `HttpServletRequest`.
    `communityUri` - the URI for the community.
  Returns
    the appropriate `CommunityContext` object, or `null`if no community with the specified URI exists.``

### getCommunityContext

    public static CommunityContext getCommunityContext(javax.servlet.http.HttpServletRequest request,
                                                       CommunityDefinition community)

  Returns the `CommunityContext` object associated with the specified request and `CommunityDefinition`. This may be useful for obtaining a `CommunityContext` if the `CommunityDefinition` has already been retrieved through a call from a method returning only `CommunityDefintion` objects, such as the `CommunityUserContext.getCommunities()` method. This method should be called every time a `CommunityContext` is needed, and the returned value should never be cached or kept as a reference, since the context object maintains a reference to the request and will be invalid on subsequent requests. This method is optimized internally to only create a new context object once per request, so there is no performance benefit to maintaing references to the return value in any case.

  Parameters
    `request` - the `HttpServletRequest`.
    `community` - the community.
  Returns
    the appropriate `CommunityContext` object.

### getCommunityContext

    public static CommunityContext getCommunityContext(javax.servlet.http.HttpServletRequest request,
                                                       CommunityDefinitionId communityId)

  Returns the `CommunityContext` object associated with the specified request and `CommunityDefinitionId`. This method should be called every time a `CommunityContext` is needed, and the returned value should never be cached or kept as a reference, since the context object maintains a reference to the request and will be invalid on subsequent requests. This method is optimized internally to only create a new context object once per request, so there is no performance benefit to maintaing references to the return value in any case.

  Parameters
    `request` - the `HttpServletRequest`.
    `communityId` - the community ID.
  Returns
    the appropriate `CommunityContext` object.

### getCommunityContext

    public static CommunityContext getCommunityContext(javax.servlet.http.HttpServletRequest request,
                                                       CommunityMembership membership)

  Returns the `CommunityContext` object associated with the specified request and `CommunityMembership` for the currently authenticated principal. This may be useful for obtaining a `CommunityContext` if the `CommunityMembership` has already been retrieved through a call from a method returning only `CommunityMembership` objects, such as the `CommunityUserContext.getCommunityMembership()` method. `CommunityContext` objects can only be obtained for the currently authenticated principal (user) or, if no authenticated principal exists for the request, the anonymous user. Since the anonymous user cannot have a membership in a community, this method will only return a `CommunityContext` if the specified membership is for the currently authenticated principal in the request. This method should be called every time a `CommunityContext` is needed, and the returned value should never be cached or kept as a reference, since the context object maintains a reference to the request and will be invalid on subsequent requests. This method is optimized internally to only create a new context object once per request, so there is no performance benefit to maintaing references to the return value in any case.

  Parameters
    `request` - the `HttpServletRequest`.
    `membership` - the membership to obtain the `CommunityContext` for. This membership must be for the authenticated principal in the request; if the membership is for any other user, this methos will return `null`.
  Returns
    the appropriate `CommunityContext` object, or `null` if no appropriate `CommunityContext` exists.

### getCommunityURL

    public static GenericURL getCommunityURL(javax.servlet.http.HttpServletRequest request,
                                             javax.servlet.http.HttpServletResponse response,
                                             CommunityURI community)

  Returns a URL to the specified community, if the URL can be determined. If the specified community is in another web application which is not deployed on this server and the URL to the webapp cannot be determined, `null` will be returned.

  Parameters
    `request` - the request object.
    `response` - the response object.
    `community` - the community to get a URL to.
  Returns
    a URL to the specified community, if the URL can be determined. If the specified community is in another web application which is not deployed on this server and the URL to the webapp cannot be determined, `null` will be returned.

### getCommunityUserContext

    public CommunityUserContext getCommunityUserContext()

  Returns the `CommunityUserContext` object backing this `CommunityContext`.

  Returns
    the `CommunityUserContext` object backing this `CommunityContext`.

### checkPermissions

    public void checkPermissions(javax.servlet.http.HttpServletResponse response,
                                 boolean updateAccess)
                          throws CommunityAccessRedirectionException

  Checks to see if the currently-logged-in (or not logged-in) individual is allowed to access the community in this `CommunityContext`, and if so, automatically updates the membership's last access date if appropriate. This method is automatically called by the framework for the "default" community (associated with the currently-viewed desktop) and does not need to be called in this case. When accessing community information outside of a community desktop (or accesssing information for a different community) this method should be called by the application to determine if the user has rights to access the community information.

  This method throws a `CommunityAccessRedirectionException` if the authenticated principal (or lack thereof) is not allowed to view the community associated with this `CommunityContext`. The exception contains information on what access violation occured and where the user can be redirected to to see the community error page or the community registration page. For portlets using community information outside of the community desktop, this information can be used to display "access denied" type error messages or offer a link to the community registration page without actually affecting a redirect.

  Note that this method may not throw an exception even if the member or membership is disabled, if the community is public. Therefore, the `isMembershipActive()` method can be used to ensure the membership and member records are not disabled.

  If the user has permission to view the community, and the community has access tracking enabled, the membership's last access date is updated if it is the first attempt at access for this community in this HttpSession and the updateAccess argument is true. In some cases, access rights may need to be ascertained without the application qualifying it as a full "access" to the community; this parameter allows control over this feature. Note that the `updateLastAccessDate()` method may be used to force updating at any time.

  The logic implemented by this method is:
  - Is the Community public?
    - Yes: Is the Community active?
      - Yes: update membership's last access date if appropriate and return.
      - No: throw an exception to redirect to the error page with error COMMUNITY_DEACTIVATED
    - No: Is a user logged in and do they have a membership in the Community?
      - Yes: Is their Community member record active?
        - Yes: Is their Community membership record active?
          - Yes: Is the Community active?
            - Yes: update membership's last access date if appropriate and return.
            - No: throw an exception to redirect to the error page with error COMMUNITY_DEACTIVATED
          - No: throw an exception to redirect to the error page with error MEMBERSHIP_DEACTIVATED
        - No: throw an exception to redirect to the error page with error MEMBER_DEACTIVATED
      - No: Is public registration enabled?
        - Yes: Is a user logged in and do they have a Community member record?
          - Yes: Is the member record active?
            - Yes: throw an exception to redirect to the registration page.
            - No: throw an exception to redirect to the error page with error MEMBER_DEACTIVATED
          - No: throw an exception to redirect to the registration page.
        - No: Is a user logged in and do they have an invitation to this Community?
          - Yes: throw an exception to redirect to the registration page.
          - No: throw an exception to redirect to the error page with error NO_PUBLIC_ACCESS

  Parameters
    `response` - the response object.
    `updateAccess` - indicates whether or not the last access date for the membership should be updated to reflect this access. See method description for a full discussion of this.
  Throws
    `CommunityAccessRedirectionException` - if the authenticated principal (or lack thereof) is not allowed to view the currently viewed community. The exception contains information on what access violation occured and where the user can be redirected to to see an explanitory error page or the community registration page.

    `isMembershipActive()`

### isMembershipActive

    public boolean isMembershipActive()

  Determines if the member and membership records associated with the authenticated principal (logged-in user) and this `CommunityContext` object are active or disabled. Note that it is possible to have an active membership and member record but to also have the community disabled; for this reason this method is not equivalent to the checkPermissions() method.

  Returns
    `true` if both the `CommunityMember` and `CommunityMembership` associated with this `CommunityContext` are active; `false` if the member or membership record does not exist or are disabled.

    `checkPermissions(javax.servlet.http.HttpServletResponse, boolean)`

### getCommunityInvitationContext

    public CommunityInvitationContext getCommunityInvitationContext()

  Returns the CommunityInvitationContext object for this community.

### getCommunity

    public CommunityDefinition getCommunity()

  Retrieves the `CommunityDefinition` for the community associated with this `CommunityContext`. This method returns a new clone of the `CommunityDefinition`.

  Returns
    the `CommunityDefinition` object for the community associated with this `CommunityContext`

### getMembership

    public CommunityMembership getMembership()

  Retrieves the `CommunityMembership` object assicated with this `CommunityContext` object, if a membership exists.

  Creates a `CommunityMembership` for the authenticated principal in the current Request object for the community associated with this `CommunityContext`. Invitations may contain information about community capabilities to grant to the new membership, so when an invitation exists, the other form of this method (which takes an Invitation object) should be used. If a community member record does not exist, it is created with default values active=`true` and external=`false`. If no user is logged in, a `NotEntitledException` is thrown.

  Returns
    a `CommunityMembership` object containing membership information.
  Throws
    `RemoteException`
    `NotEntitledException` - if there is no user logged in.
    `DuplicateObjectException` - if a membership already exists for the specified member and community.

### createMembership

    public CommunityMembership createMembership(Invitation invitation)
                                         throws IllegalArgumentException,
