get

public GitFileDiff get(GitFileDiffCacheKey key)
                throws DiffNotAvailableException

Description copied from interface: GitFileDiffCache

Returns the git file diff for a single file path identified by its key.

Specified by:

get in interface GitFileDiffCache

Parameters:

key - identifies two git trees, a specific file path and other diff parameters.

Returns:

the file diff for a single file path identified by its key.

Throws:

DiffNotAvailableException - if the tree IDs of the key are invalid for this project or if file contents could not be read.

getAll

public com.google.common.collect.ImmutableMap<GitFileDiffCacheKey,GitFileDiff> getAll(Iterable<GitFileDiffCacheKey> keys)
                                                                               throws DiffNotAvailableException

Description copied from interface: GitFileDiffCache

Returns the file diff for a collection of file paths identified by their keys.

Specified by:

getAll in interface GitFileDiffCache

Parameters:

keys - identifying different file paths of different projects.

Returns:

a map of the input keys to their corresponding git file diffs.

Throws:

DiffNotAvailableException - if the diff failed to be evaluated for one or more of the input keys due to invalid tree IDs or if file contents could not be read.
