Method Detail

messageUuid

public static java.lang.String messageUuid()

Returns:

a new unique identifier for change message entities.

nextPatchSetIdFromAllRefsMap

public static PatchSet.Id nextPatchSetIdFromAllRefsMap(java.util.Map<java.lang.String,org.eclipse.jgit.lib.Ref> allRefs,
                                                       PatchSet.Id id)

Get the next patch set ID from a previously-read map of all refs.

Parameters:

allRefs - map of full ref name to ref.

id - previous patch set ID.

Returns:

next unused patch set ID for the same change, skipping any IDs whose corresponding ref names appear in the allRefs map.

nextPatchSetIdFromChangeRefs

public static PatchSet.Id nextPatchSetIdFromChangeRefs(java.util.Collection<java.lang.String> changeRefNames,
                                                       PatchSet.Id id)

Get the next patch set ID from a previously-read map of refs below the change prefix.

Parameters:

changeRefNames - existing full change ref names with the same change ID as id.

id - previous patch set ID.

Returns:

next unused patch set ID for the same change, skipping any IDs whose corresponding ref names appear in the changeRefs map.

nextPatchSetId

public static PatchSet.Id nextPatchSetId(PatchSet.Id id)

Get the next patch set ID just looking at a single previous patch set ID.

This patch set ID may or may not be available in the database; callers that want a previously-unused ID should use nextPatchSetIdFromAllRefsMap(java.util.Map<java.lang.String, org.eclipse.jgit.lib.Ref>, com.google.gerrit.reviewdb.client.PatchSet.Id) or nextPatchSetIdFromChangeRefs(java.util.Collection<java.lang.String>, com.google.gerrit.reviewdb.client.PatchSet.Id).

Parameters:

id - previous patch set ID.

Returns:

next patch set ID for the same change, incrementing by 1.

nextPatchSetId

public static PatchSet.Id nextPatchSetId(org.eclipse.jgit.lib.Repository git,
                                         PatchSet.Id id)
                                  throws java.io.IOException

Get the next patch set ID from scanning refs in the repo.

Parameters:

git - repository to scan for patch set refs.

id - previous patch set ID.

Returns:

next unused patch set ID for the same change, skipping any IDs whose corresponding ref names appear in the repository.

Throws:

java.io.IOException

status

public static java.lang.String status(Change c)
