Method Detail

getOpenBranches

@NotNull
public List<VcsBranch> getOpenBranches(@NotNull
                                                VcsRepositoryData repositoryData)
                                         throws RepositoryException

Description copied from interface: VcsBranchDetector

Set of open branches that are discovered in the repository. Returns empty collection if no branches at all (can that happen?). Used for monitoring repositories for new branches. An open branch is a branch that is considered 'open' by underlying VCS - it has nothing to do with the actual development on that branch (recent commits or so).

Specified by:

getOpenBranches in interface VcsBranchDetector

Returns:

List of branch names. May be empty.

Throws:

RepositoryException

getFirstCommitApproximation

@NotNull
public CommitContext getFirstCommitApproximation(@NotNull
                                                          VcsRepositoryData repositoryData)
                                                   throws RepositoryException

Description copied from interface: VcsBranchDetector

Retrieve an old, preferably the first commit on a branch. Implementations must not return null. The default implementation may return null.

Specified by:

getFirstCommitApproximation in interface VcsBranchDetector

Throws:

RepositoryException

getLastCommit

@NotNull
public CommitContext getLastCommit(@NotNull
                                            VcsRepositoryData repositoryData)
                                     throws RepositoryException

Description copied from interface: VcsBranchDetector

Retrieve last commit on the branch set on this Repository. Method is used by Chain Branch automatic expiry. If this method returns null Chain Branch is not expired.

Specified by:

getLastCommit in interface VcsBranchDetector

Returns:

the last commit

Throws:

RepositoryException

getVcsIdForExecutor

@Nullable
public ContextualVcsId<VcsBranchDetector> getVcsIdForExecutor(@NotNull
                                                                        VcsRepositoryData vcsRepositoryData)

Description copied from interface: IdentifyingExecutor

Returned id has to fulfill the following: Given two VcsRepositoryData objects A and B, and executor e returning equal ContextualVcsId (in terms of equals()), for any operation foo() provided by the executor, the calls e::foo(A) and e::foo(B) should be equivalent. To be more precise: given any time point t and any variable context v, calling a::foo(A) should yield the same results as calling e::foo(B). Given the above it follows that - calculation of the id should take into account global and plan variables. This means, that calling this method on the same object in different variable context can (possibly must) yield different results. - equal ids need not (and should not) guarantee equal call results over indefinite time. In particular, result of e:foo(A).equals(e::foo(A)) is allowed to be false, since 2 calls to e::foo(A) do not happen at the same time. Example: 2 git repositories with the same url and credentials are considered equal in context of VcsBranchDetector. If they also point to the same branch, they are considered equal in context of VcsChangeDetector

Specified by:

getVcsIdForExecutor in interface IdentifyingExecutor<VcsBranchDetector>

Returns:

the id of repository, can be null if no feasible identification algorithm exists
