Constructor Detail

ResourceDiffTree

public ResourceDiffTree()
Method Detail

getResourceFor

public static 
IResource getResourceFor(
IDiff node)
Get the resource for the diff node that was obtained from an IResourceDiffTree.

Parameters:
node - the diff node.
Returns:
the resource for the diff node

getDiff

public 
IDiff getDiff(
IResource resource)
Description copied from interface: IResourceDiffTree
Return the diff for the given resource. This method is a convenience method that uses the path of the resource to access the diff.

Specified by:
getDiff in interface IResourceDiffTree
Parameters:
resource - a resource
Returns:
the diff associated with the resource or null if the resource does not have any changes.

getResource

public 
IResource getResource(
IDiff diff)
Description copied from interface: IResourceDiffTree
Return the resource associated with the given diff. This method will only return meaningful results for diffs which were obtained from this tree.

Specified by:
getResource in interface IResourceDiffTree
Parameters:
diff - a diff
Returns:
the resource associated with the given diff

accept

public void accept(
ResourceTraversal[] traversals,
                   
IDiffVisitor visitor)
Description copied from interface: IResourceDiffTree
Visit all diffs in this tree that are covered by the given traversals.

Specified by:
accept in interface IResourceDiffTree
Parameters:
traversals - the set of traversals whose diffs are to be visited
visitor - a diff visitor

getDiffs

public 
IDiff[] getDiffs(
ResourceTraversal[] traversals)
Description copied from interface: IResourceDiffTree
Return all the diffs in the tree that are contained in the given traversals.

Specified by:
getDiffs in interface IResourceDiffTree
Parameters:
traversals - the traversals
Returns:
all the diffs in the tree that are contained in the given traversals

getDiffs

public 
IDiff[] getDiffs(
IResource resource,
                        int depth)
Description copied from interface: IResourceDiffTree
Return all the diffs in the tree that are found for the given resource when traversed to the given depth.

Specified by:
getDiffs in interface IResourceDiffTree
Parameters:
resource - the resource
depth - the depth
Returns:
all the diffs in the tree that are found for the given resource when traversed to the given depth

members

public 
IResource[] members(
IResource resource)
Description copied from interface: IResourceDiffTree
Return the members of the given resource that either have diffs in this tree of contain descendants that have diffs in this tree.

Specified by:
members in interface IResourceDiffTree
Parameters:
resource - a resource
Returns:
the members of the given resource that either have diffs in this tree of contain descendants that have diffs in this tree

getAffectedResources

public 
IResource[] getAffectedResources()
Description copied from interface: IResourceDiffTree
Return all resources that contain diffs in this diff tree.

Specified by:
getAffectedResources in interface IResourceDiffTree
Returns:
all resources that contain diffs in this diff tree

add

public void add(
IDiff delta)
Description copied from class: DiffTree
Add the given IDiff to the tree. A change event will be generated unless the call to this method is nested in between calls to beginInput() and endInput(IProgressMonitor) in which case the event for this addition and any other sync set change will be fired in a batched event when endInput is invoked.

Invoking this method outside of the above mentioned block will result in the endInput(IProgressMonitor) being invoked with a null progress monitor. If responsiveness is required, the client should always nest sync set modifications within beginInput/endInput.

Overrides:
add in class DiffTree
Parameters:
delta - the delta to be added to this set.

remove

public void remove(
IResource resource)
Remove the diff associated with the given resource from the tree.

Parameters:
resource - the resource

hasMatchingDiffs

public boolean hasMatchingDiffs(
ResourceTraversal[] traversals,
                                
FastDiffFilter filter)
Description copied from interface: IResourceDiffTree
Return whether the this diff tree contains any diffs that match the given filter within the given traversals.

Specified by:
hasMatchingDiffs in interface IResourceDiffTree
Parameters:
traversals - the traversals
filter - the diff node filter
Returns:
whether the given diff tree contains any deltas that match the given filter
