Class PortalGroup

  • All Implemented Interfaces:
    JsonSerializable, Loadable
    public final class PortalGroup
extends Object
implements Loadable, JsonSerializable
    Represents a group within a portal.

    Collections of fully populated PortalGroup objects can be obtained by calling the Portal.findGroupsAsync(PortalQueryParameters), Portal.fetchFeaturedGroupsAsync(), PortalItem.fetchGroupsAsync() and PortalUser.getGroups() methods. The load status of such objects is LoadStatus.LOADED.

    Alternatively a PortalGroup object can be constructed using PortalGroup(Portal, String) if the group ID is known. In that case the load status is initially LoadStatus.NOT_LOADED and the object needs to be loaded to populate its properties.

    The portal group owner is automatically an administrator and is returned in the list of admins. The access property determines the visibility of the group to other users. If the group is private, no one except the administrators and the members of the group can see it. If the group is shared with an organization, then all members of the organization can see the group.

    Administrators can invite, add to, and remove members from a group, and also update and delete the group. The administrator for an organization may also reassign the group to another member of the organization. Group members may leave the group. Authenticated users may apply to join a group.

      • toJson

        public String toJson()
        Description copied from interface: JsonSerializable
        Serializes this object to a JSON string. Note that unknown JSON is omitted from the serialized string.
        Specified by:
        toJson in interface JsonSerializable
        Returns:
        a JSON string

      • getUnknownJson

        public Map<String,​Object> getUnknownJson()
        Description copied from interface: JsonSerializable
        If this object was created from JSON, this method gets unknown data from the source JSON. Unknown JSON is a Map of values that were in the source JSON but are not known by the Runtime and therefore not exposed in the API.
        Specified by:
        getUnknownJson in interface JsonSerializable
        Returns:
        an unmodifiable Map containing unknown JSON data. The keys are Strings containing names. The types of the values depend on the types of tokens within the JSON as follows:
        • a Map<String, Object> represents an object in the JSON
        • a List<Object> represents an array in the JSON
        • a String represents a string in the JSON
        • a Double represents a number in the JSON
        • a Boolean represents true or false in the JSON
        • null represents null in the JSON

      • getUnsupportedJson

        public Map<String,​Object> getUnsupportedJson()
        Description copied from interface: JsonSerializable
        If this object was created from JSON, this method gets unsupported data from the source JSON. Unsupported JSON is a Map of values that are supported by webmaps and known to the version of the webmap specification the API supports (see system requirements), but are not explicitly exposed through the Runtime API.
        Specified by:
        getUnsupportedJson in interface JsonSerializable
        Returns:
        an unmodifiable Map containing unsupported JSON data. The keys are Strings containing names. The types of the values depend on the types of tokens within the JSON as follows:
        • a Map<String, Object> represents an object in the JSON
        • a List<Object> represents an array in the JSON
        • a String represents a string in the JSON
        • a Double represents a number in the JSON
        • a Boolean represents true or false in the JSON
        • null represents null in the JSON

      • getLoadStatus

        public LoadStatus getLoadStatus()
        Description copied from interface: Loadable
        Returns the LoadStatus of the loadable resource.
        Specified by:
        getLoadStatus in interface Loadable
        Returns:
        the LoadStatus of the loadable resource

      • cancelLoad

        public void cancelLoad()
        Description copied from interface: Loadable
        Cancels loading metadata for the object.

        Cancels loading the metadata if the object is loading, and always invokes the done loading listener.

        A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling this method and the resource will transition from LoadStatus.LOADING to LoadStatus.FAILED_TO_LOAD state. If the load operation was successfully cancelled, a CancellationException will be returned from Loadable.getLoadError().

        Cancellation should be used carefully because all enqueued done loading listeners for that resource instance will get invoked with an error stating that the operation was cancelled. Thus, one component in the application can cancel the load operation initiated by other components.

        This method does nothing if the resource is not in LoadStatus.LOADING state.

        Specified by:
        cancelLoad in interface Loadable

      • loadAsync

        public void loadAsync()
        Description copied from interface: Loadable
        Loads the metadata of the loadable resource asynchronously.

        The load status changes from LoadStatus.NOT_LOADED to LoadStatus.LOADING. A listener can be added via Loadable.addDoneLoadingListener(java.lang.Runnable) that is invoked upon completion of the asynchronous load operation.

        If the load operation completes successfully, the load status will be LoadStatus.LOADED, which means the resource has loaded its metadata.

        If the load operation failed, the load status will be LoadStatus.FAILED_TO_LOAD and the error can be retrieved by calling Loadable.getLoadError().

        This method can be called concurrently and repeatedly, but only one attempt is ever made to perform the load operation. If a load operation is already in progress (LoadStatus.LOADING state) when loadAsync is called, it simply piggy-backs on the outstanding operation and the done loading listener added to the loadable resource is enqueued to be invoked when that operation completes. If the operation has already completed (LoadStatus.LOADED or LoadStatus.FAILED_TO_LOAD state) when loadAsync is called, the done loading listener is immediately invoked when added to the loadable resource.

        If a loadable resource has failed to load, calling loadAsync on it subsequently will not change its state. The done loading listener will be invoked immediately when added to the loadable resource. In order to retry loading the resource, Loadable.retryLoadAsync() needs to be used.

        A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling Loadable.cancelLoad().

        Specified by:
        loadAsync in interface Loadable

      • retryLoadAsync

        public void retryLoadAsync()
        Description copied from interface: Loadable
        Loads or retries loading metadata for the object asynchronously.

        Will retry loading the metadata if the object's load status is LoadStatus.FAILED_TO_LOAD. Will load the object if it is not loaded. Will not retry to load the object if the object is loaded.

        For more details on the load process see Loadable.loadAsync().

        Specified by:
        retryLoadAsync in interface Loadable

      • addDoneLoadingListener

        public void addDoneLoadingListener​(Runnable listener)
        Description copied from interface: Loadable
        Adds a listener to the loadable resource that is invoked when loading has completed.

        The listener may be added at any point, whether the loadable resource has already completed loading or not.

        • For resources that are not loaded when the listener is added (LoadStatus is NOT_LOADED or LOADING): When the resource completes loading, the listener will be invoked on the UI thread if it is added from the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.
        • For resources that are already loaded when the listener is added (LoadStatus is LOADED or FAILED_TO_LOAD): The listener will be called immediately, on the current thread.

        Alternatively, to be notified when there is any change in the load status, use the Loadable.addLoadStatusChangedListener(LoadStatusChangedListener) method instead.

        Specified by:
        addDoneLoadingListener in interface Loadable
        Parameters:
        listener - a Runnable that is invoked upon completion of the load operation

      • removeDoneLoadingListener

        public boolean removeDoneLoadingListener​(Runnable listener)
        Description copied from interface: Loadable
        Removes a done loading listener from the loadable resource.
        Specified by:
        removeDoneLoadingListener in interface Loadable
        Parameters:
        listener - the listener to be removed
        Returns:
        true if the listener was removed, otherwise false

      • addLoadStatusChangedListener

        public void addLoadStatusChangedListener​(LoadStatusChangedListener listener)
        Description copied from interface: Loadable
        Adds a LoadStatusChangedListener to the loadable resource that is invoked whenever the load status changes.

        Adding this listener on the UI thread will cause it to be invoked on the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.

        The listener will not be called if added to a loadable resource that has already completed loading. To be notified when a loadable resource has completed loading, including if the resource is already loaded when the listener is added, use the Loadable.addDoneLoadingListener(Runnable) method.

        Specified by:
        addLoadStatusChangedListener in interface Loadable
        Parameters:
        listener - the LoadStatusChangedListener to be added

      • removeLoadStatusChangedListener

        public boolean removeLoadStatusChangedListener​(LoadStatusChangedListener listener)
        Description copied from interface: Loadable
        Removes a LoadStatusChangedListener from the loadable resource.
        Specified by:
        removeLoadStatusChangedListener in interface Loadable
        Parameters:
        listener - the LoadStatusChangedListener to be removed
        Returns:
        true if the listener was removed, otherwise false
