Method Detail

include

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

Description copied from class: CommitDiffFilter

Handle the differences introduced by given commit.

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

Overrides:

include in class CommitDiffFilter

Parameters:

commit - non-null

diffs - non-null

Returns:

true to continue, false to abort

getDuplicates

public Map<org.eclipse.jgit.revwalk.RevCommit,DuplicateContainer> getDuplicates()

Get the duplicates

Returns:

non-null but possibly empty map

hasDuplicates

public boolean hasDuplicates()

Were any duplicate blobs detected for all commits visited?

Returns:

true if duplicates exist, false otherwise

reset

public CommitFilter reset()

Description copied from class: CommitFilter

Resets the filter state. The base implementation does nothing by default and sub-classes should override if custom reset logic exists.

Overrides:

reset in class CommitFilter

Returns:

this filter

clone

public org.eclipse.jgit.revwalk.filter.RevFilter clone()

Description copied from class: CommitFilter

Clones this filter.

The default implementation throws a UnsupportedOperationException and sub-classes should override if filter cloning is supported.
