    IAdaptable

    public abstract class AbstractRefactoringHistoryResourceMapping
    extends ResourceMapping
    Partial implementation of a resource mapping for a refactoring history object.

    Note: this class is intended to be implemented by clients which need to enhance a model provider with a refactoring model.

    • Constructor Detail

      • AbstractRefactoringHistoryResourceMapping

        protected AbstractRefactoringHistoryResourceMapping​(RefactoringHistory history)
        Creates a new abstract refactoring history resource mapping.
        Parameters:
        history - the refactoring history
    • Method Detail

      • equals

        public boolean equals​(Object object)
        Description copied from class: ResourceMapping
        Override equals to compare the model objects of the mapping in order to determine equality.
        Overrides:
        equals in class ResourceMapping
        Parameters:
        object - the object to compare
        Returns:
        true if the receiver is equal to the given object, and false otherwise.
      • getModelObject

        public final Object getModelObject()
        Description copied from class: ResourceMapping
        Returns the application model element associated with this resource mapping.
        Specified by:
        getModelObject in class ResourceMapping
        Returns:
        the application model element associated with this resource mapping.
      • getProjects

        public final IProject[] getProjects()
        Description copied from class: ResourceMapping
        Returns the projects that contain the resources that constitute this application model.
        Specified by:
        getProjects in class ResourceMapping
        Returns:
        the projects
      • getResource

        public final IResource getResource()
        Returns the associated resource.

        This method only returns a meaningful result if the history contains refactorings of a single project.

        Returns:
        the associated resource, or null if the refactoring history contains workspace refactoring descriptors only, or if it contains refactoring descriptors from multiple projects.
      • getTraversals

        public final ResourceTraversal[] getTraversals​(ResourceMappingContext context,
                                                       IProgressMonitor monitor)
                                                throws CoreException
        Description copied from class: ResourceMapping
        Returns one or more traversals that can be used to access all the physical resources that constitute the logical resource. A traversal is simply a set of resources and the depth to which they are to be traversed. This method returns an array of traversals in order to provide flexibility in describing the traversals that constitute a model element.

        Subclasses should, when possible, include all resources that are or may be members of the model element. For instance, a model element should return the same list of resources regardless of the existence of the files on the file system. For example, if a logical resource called "form" maps to "/p1/form.xml" and "/p1/form.java" then whether form.xml or form.java existed, they should be returned by this method.

        In some cases, it may not be possible for a model element to know all the resources that may constitute the element without accessing the state of the model element in another location (e.g. a repository). This method is provided with a context which, when provided, gives access to the members of corresponding remote containers and the contents of corresponding remote files. This gives the model element the opportunity to deduce what additional resources should be included in the traversal.

        Specified by:
        getTraversals in class ResourceMapping
        Parameters:
        context - gives access to the state of remote resources that correspond to local resources for the purpose of determining traversals that adequately cover the model element resources given the state of the model element in another location. This parameter may be null, in which case the implementor can assume that only the local resources are of interest to the client.
        monitor - a progress monitor, or null if progress reporting is not desired
        Returns:
        a set of traversals that cover the resources that constitute the model element
        Throws:
        CoreException - if the traversals could not be obtained.
