Description copied from interface: TreeModification

Returns a list of PathEdits which are necessary in order to achieve the desired modification of the Git tree. The order of the PathEdits can be crucial and hence shouldn't be changed.

Specified by:

getPathEdits in interface TreeModification

Parameters:

repository - the affected Git repository

treeId - tree to which the modification is applied. A value of ObjectId.zero() indicates an empty tree.

parents - parent commits of the commit to whose tree this modification is applied

Returns:

an ordered list of necessary PathEdits

Throws:

IOException - if problems arise when accessing the repository

getFilePaths

public com.google.common.collect.ImmutableSet<String> getFilePaths()

Description copied from interface: TreeModification

Indicates all file paths affected by this TreeModification. If the modification refers to several file paths (e.g. renaming a file), all of them must be returned.

Specified by:

getFilePaths in interface TreeModification

Returns:

all affected file paths
