org.eclipse.ltk.core.refactoring.model.AbstractRefactoringHistoryResourceMapping
-
All Implemented Interfaces:
-

-
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.
-
Since:
- 3.2

AbstractRefactoringHistoryResourceMapping
protected AbstractRefactoringHistoryResourceMapping(
RefactoringHistory history)
- Creates a new abstract refactoring history resource mapping.
-
Parameters:
-
history - the refactoring history
equals
public boolean equals(
Object object)
- 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()
- 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()
- 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
- 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.
hashCode
public int hashCode()
- Override hashCode to use the model object.
-
-
Overrides:
-
hashCode
in class
ResourceMapping
