Constructor Detail

FilteredRenameDetector

public FilteredRenameDetector(Repository repository)

Parameters:

repository - The repository in which to check for renames.

public FilteredRenameDetector(RenameDetector renameDetector)

Parameters:

renameDetector - The RenameDetector to use when checking for renames.

Method Detail

compute

public List<DiffEntry> compute(List<DiffEntry> diffs,
                               PathFilter pathFilter)
                        throws IOException

Parameters:

diffs - The set of changes to check.

pathFilter - Filter out changes that didn't affect this path.

Returns:

The subset of changes that affect only the filtered path.

Throws:

IOException

compute

public List<DiffEntry> compute(List<DiffEntry> changes,
                               List<PathFilter> pathFilters)
                        throws IOException

Tries to avoid computation overhead in RenameDetector.compute() by filtering diffs related to the path filters only.

Note: current implementation only optimizes added or removed diffs, further optimization is possible.

Parameters:

changes - The set of changes to check.

pathFilters - Filter out changes that didn't affect these paths.

Returns:

The subset of changes that affect only the filtered paths.

Throws:

IOException
