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
