Interface IResourceDiffTree

All Superinterfaces:

IDiffTree

All Known Implementing Classes:

ResourceDiffTree

public interface IResourceDiffTree
extends IDiffTree

A resource diff tree provides access to a tree of IDiff instances that either contain IResourceDiff nodes or IThreeWayDiff nodes that contain IResourceDiff nodes as the local and remote changes. For efficiency reasons, the tree only provides diffs for resources that have changes. Resources that do not contain a change but are returned from the tree will contain children in the set.

Since:

3.2

Restriction:

This interface is not intended to be implemented by clients. Clients can use ResourceDiffTree instead.

Method Detail

getDiff

IDiff getDiff(IResource resource)

Return the diff for the given resource. This method is a convenience method that uses the path of the resource to access the diff.

Parameters:

resource - a resource

Returns:

the diff associated with the resource or null if the resource does not have any changes.

getResource

IResource getResource(IDiff diff)

Return the resource associated with the given diff. This method will only return meaningful results for diffs which were obtained from this tree.

Parameters:

diff - a diff

Returns:

the resource associated with the given diff

accept

void accept(ResourceTraversal[] traversals,
            IDiffVisitor visitor)

Visit all diffs in this tree that are covered by the given traversals.

Parameters:

traversals - the set of traversals whose diffs are to be visited

visitor - a diff visitor

getDiffs

IDiff[] getDiffs(ResourceTraversal[] traversals)

Return all the diffs in the tree that are contained in the given traversals.

Parameters:

traversals - the traversals

Returns:

all the diffs in the tree that are contained in the given traversals

getDiffs

IDiff[] getDiffs(IResource resource,
                 int depth)

Return all the diffs in the tree that are found for the given resource when traversed to the given depth.

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

IResource[] members(IResource resource)

Return the members of the given resource that either have diffs in this tree of contain descendants that have diffs in this tree.

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

IResource[] getAffectedResources()

Return all resources that contain diffs in this diff tree.

Returns:

all resources that contain diffs in this diff tree

hasMatchingDiffs

boolean hasMatchingDiffs(ResourceTraversal[] traversals,
                         FastDiffFilter filter)

Return whether the this diff tree contains any diffs that match the given filter within the given traversals.

Parameters:

traversals - the traversals

filter - the diff node filter

Returns:

whether the given diff tree contains any deltas that match the given filter
