Interface RepoCommand.RemoteReader

All Known Implementing Classes:

RepoCommand.DefaultRemoteReader

Enclosing class:

RepoCommand

public static interface RepoCommand.RemoteReader

A callback to get ref sha1 of a repository from its uri. We provided a default implementation RepoCommand.DefaultRemoteReader to use ls-remote command to read the sha1 from the repository and clone the repository to read the file. Callers may have their own quicker implementation.

Since:

3.4

                                                 String ref,
