Constructor Detail

CommitDiffFilter

public CommitDiffFilter()

Create commit diff filter

CommitDiffFilter

public CommitDiffFilter(boolean detectRenames)

Create commit diff filter

Parameters:

detectRenames - true to detect renames, false otherwise

Method Detail

setRepository

public CommitFilter setRepository(org.eclipse.jgit.lib.Repository repository)

Description copied from class: CommitFilter

Set the repository for the walk that is about to begin.

Overrides:

setRepository in class CommitFilter

Returns:

this filter

createTreeWalk

protected org.eclipse.jgit.treewalk.TreeWalk createTreeWalk(org.eclipse.jgit.revwalk.RevWalk walker,
                                                            org.eclipse.jgit.revwalk.RevCommit commit)

Create tree walk to compute differences for the given commits

Sub-classes may override this method to create a custom tree walk with different filtering options set.

The last tree in the tree walk is assumed to be the tree of the current commit

Parameters:

walker -

commit -

Returns:

tree walk

include

public boolean include(org.eclipse.jgit.revwalk.RevWalk walker,
                       org.eclipse.jgit.revwalk.RevCommit commit)
                throws IOException

Specified by:

include in class org.eclipse.jgit.revwalk.filter.RevFilter

Throws:

IOException

isFileDiff

protected boolean isFileDiff(org.eclipse.jgit.diff.DiffEntry diff)

Is the given diff entry a file?

Parameters:

diff -

Returns:

true if a regular or executable file, false otherwise

include

public boolean include(org.eclipse.jgit.revwalk.RevWalk walker,
                       org.eclipse.jgit.revwalk.RevCommit commit,
                       Collection<org.eclipse.jgit.diff.DiffEntry> diffs)
                throws IOException

Handle the differences introduced by given commit.

Sub-classes should override this method. The default implementation calls include(RevCommit, Collection).

Parameters:

walker - non-null

commit - non-null

diffs - non-null

Returns:

true to continue, false to abort

Throws:

IOException

include

public boolean include(org.eclipse.jgit.revwalk.RevCommit commit,
                       Collection<org.eclipse.jgit.diff.DiffEntry> diffs)
                throws IOException

Handle the differences introduced by given commit.

Sub-classes should override this method. The default implementation returns true in all cases.

Parameters:

commit - non-null

diffs - non-null

Returns:

true to continue, false to abort

Throws:

IOException
