This document will have Mylar 2.0 specific API changes added to it as we make them. If interested in keeping up with these changes we suggest setting a watch for this page.

Porting from Mylar 1.0 to 2.0

Pending Changes

The following changes are being considered but not yet implemented.

• TaskRepository:
  • rename getKind() to getConnectorKind()
  • Make class FINAL

• AbstractRepositoryConnector:
  • rename createTaskFromExistingKey(..) to addExistingTask(..)
  • rename getRepositoryType() to getConnectorKind()

• AbstractRepositoryTask
• rename getRepositoryKind() to getConnectorKind()

• Task
• renamte getRepositoryKind() to getConnectorKind()

• IRepositoryConstants
  • rename PROPERTY_KIND to PROPERTY_CONNECTOR_KIND

General

• All library dependencies have moved
• MylarStatusHandler and IStatusHandler
  • moved from org.eclipse.mylar.context.core to org.eclipse.mylar.core

Tasks API

• AbstractRepositoryConnector
  • + getLastSyncTimestamp(TaskRepository repository, Set<AbstractRepositoryTask> changedTasks) (may change as part of bug#176934)
  • getSupportedVersions() has been removed (#1768159)

• AbstractRepositoryConnectorUi
  • openRemoteTask(String repositoryUrl, String id): removed, this method no longer needs to be implemented by the connector. Instead classes can rely on the new openRepositoryTask(..) method, and override it if necessary.
  • getRepositoryUrl and all ID/URL methods: now final, change via setters
  • + findHyperlinks(...) override to detect hyperlinks in editors

• AbstractRepositorySettingsPage validation changes.
  • setNeedsValidation(boolean needsValidation) if true validate button will be visible
  • getValidator(TaskRepository repository) return an instance of Validator.

• AbstractRepositoryTaskEditor
  • attributeChanged() Anything that needs to be saved must be in attribute form and passed to this method. Most if this is all done for you but if you override AbstractRepositoryTaskEditor.createCustomAttributeLayout() then you will want to ensure that attributeChanged is called upon editing. Utility method createTextField() handles this call.
  • createLabel() Utility method added. It will put an '*' at the front of the label if the attribute has been modified. Eventually this will be applied upon editing but currently only happens after re-freshing or re-opening the editor.
  • SECTION_NAME is an enum that holds default titles for the default sections. To override these default titles, set the appropriate (SECTION_NAME, new name) in alternateSectionLabels on AbstractRepositoryTaskEditor.
  • updateEditor() refreshes editor with new input in-place.

• AbstractRepositoryQuery
  • Constrctor no longer takes number of hits. Connectors can use QueryHitCollector.MAX_HITS (currently 5000) when setting max number of hits to return.

• AbstractRepositoryTask .....updates in progress
  • getIdLabel() -> getTasKey()
  • constructor changed
  • getLastRefreshTimeInMinutes(Date) removed
  • no more static methods (use RepositoryTaskHandleUtil)
  • Replace this idiom:

   String handleIdentifier = AbstractRepositoryTask.getHandle(repository.getUrl(), taskId);
   ITask task = TasksUiPlugin.getTaskListManager().getTaskList().getTask(handle);

• • with:

   ITask task = TasksUiPlugin.getTaskListManager().getTaskList().getTask(repository.getUrl(), taskId);

• AbstractQueryHit
  • setDescription(..) renamed to setSummary(..)

• AttributeContainer
  • getAttributeFactory() new method

• DateRangeContainer
  • getChildren() now returns set of underlying task objects (not DateRangeActivityDelegates which will be deprecated)
  • getDateRangeDelegates() returns the delegate formerly returned by getChildren()

• ITaskListElement: now extends java.lang.Comparable, so Collections support of sorting can be used, since task list elements have a natural ordering. Default implementations are provided for tasks and containers. (bug 171590)

• ITaskDataHandler
  • getChangedSinceLastSync() method moved to AbstractRepositoryConnector
  • New comment now held in an attribute: RepositoryTaskAttribute.COMMENT_NEW will need to update handler and factory to produce connector specific attribute
  • initializeTaskData(TaskRepository repository, RepositoryTaskData data, IProgressMonitor monitor) called by NewTaskWizard to initialize new taskData objects (currently only in use by Trac but will adopt).
  • getAttributeFactory(String repositoryUrl, String repositoryKind, String taskKind) signature changed
  • getDateForAttributeType(...) moved to AbstractAttributeFactory

• ITaskListExternalizer
  • readTask(..) renamed to createTask(..), no longer needs to set taskId, label, or repositoryUrl
• DelegatingTaskExternalizer
  • readTaskInfo(..) and readQueryHitInfo(..) are now called automatically and are private. Use your createTask(..) or createQueryHit(..) methods to customize reading additional attributes.

• TaskRepository
  • TaskRepository.isAnonymous()
  • TaskRepository.setAnonymous(boolean)
  • (-) TaskRepository.getDefaultProxy() (Renamed and moved to WebClientUtil.getPlatformProxy())

• RepositorySynchronizationManager
  • updateOfflineState is now saveIncoming and saveOutgoing.
  • discardOutgoing discards any pending outgoing changes

• RepositoryTaskAttribute
  • getID() -> getId()

• RepositoryTaskData
  • constructor now requires a task kind (string) (i.e. Task.DEFAULT_TASK_KIND)
  • getTaskKind return the task kind
  • setNew(boolean) signifies that this is unsubmitted task data. Used by editor factory to determine if existing or new editor to be opened.

• Task .....updates in progress
  • getTooltipText(): deleted, not used
  • Due dates are now supported getDueDate(), setDueDate()
  • handleIdentifier: now private
  • get/setUrl are now get/setTaskUrl (to disambiguate with get/setRepositoryUrl())
  • (-) getElapsedTime()
  • (-) setElapsedTime()

• TaskEditor
  • protected void pageChange(intNewPageIndex) method removed (only called super)

• TaskList
  • getChangeListeners(): returns a Set instead of List

• TaskListImages
  • renamed to TasksUiImages (still an internal class, should move to API)

• TaskListManager
  • setDueDate() used to set due date on a task and cause notification of local info changed.
  • isDue(ITask) true if task's due date isn't null and date has past

• TasksUiUtil
  • openUrl(String url): moved to openBrowser(String url)

• QueryHitCollector
  • MAX_HITS constant can be used as standard default number of hits handled per query. User notified when >= hits returned.

Context Framework

• AbstractContextStore
  • notifyContextStoreMoved(): change to contextStoreMoved()
• AbstractContextStructureBridge
  • getDegreesOfSeparation(): moved to AbstractRelationProvider
  • getRelationshipProviders(): moved to extensions point, e.g.:

 <extension point="org.eclipse.mylar.context.core.bridges">
    <relationProvider
          class="org.eclipse.mylar.internal.java.search.JavaImplementorsProvider"
          contentType="java"/>
 </extension>

Monitor Framework

• MylarMonitorUiPlugin
  • (-) setInactivityTimeout(...)

• org.eclipse.mylar.monitor: split into monitor.core and monitor.ui, organize imports and update extension point IDs
• HandleObfuscator
  • moved to InteractionEventObfuscator

• org.eclipse.mylar.monitor.usage.core and org.eclipse.mylar.monitor.usage.ui
  • moved to ..mylar.monitor.core, ..mylar.monitor.usage and ..mylar.monitor.usage.internal
