Method Detail

getId

public Change.Id getId()

getNotes

public ChangeNotes getNotes()

Returns:

notes for the state of this change prior to this update. If this update is part of a series managed by a NoteDbUpdateManager, then this reflects the state prior to the first update in the series. A null return value can only happen when the change is being rebuilt from NoteDb. A change that is in the process of being created will result in a non-null return value from this method, but a null return value from AbstractChangeNotes.getRevision().

getChange

public Change getChange()

getWhen

public java.util.Date getWhen()

getPatchSetId

public PatchSet.Id getPatchSetId()

setPatchSetId

public void setPatchSetId(PatchSet.Id psId)

getAccountId

public Account.Id getAccountId()

getNullableAccountId

public Account.Id getNullableAccountId()

newIdent

protected org.eclipse.jgit.lib.PersonIdent newIdent(Account.Id authorId,
                                                    java.util.Date when)

isEmpty

public abstract boolean isEmpty()

Whether no updates have been done.

isRootOnly

public boolean isRootOnly()

Wether this update can only be a root commit.

getProjectName

protected abstract Project.NameKey getProjectName()

Returns:

the NameKey for the project where the update will be stored, which is not necessarily the same as the change's project.

getRefName

protected abstract java.lang.String getRefName()

setParentCommit

protected void setParentCommit(org.eclipse.jgit.lib.CommitBuilder cb,
                               org.eclipse.jgit.lib.ObjectId parentCommitId)

applyImpl

protected abstract org.eclipse.jgit.lib.CommitBuilder applyImpl(org.eclipse.jgit.revwalk.RevWalk rw,
                                                                org.eclipse.jgit.lib.ObjectInserter ins,
                                                                org.eclipse.jgit.lib.ObjectId curr)
                                                         throws java.io.IOException

Create a commit containing the contents of this update.

Parameters:

ins - inserter to write to; callers should not flush.

Returns:

a new commit builder representing this commit, or null to indicate the meta ref should be deleted as a result of this update. The parent, author, and committer fields in the return value are always overwritten. The tree ID may be unset by this method, which indicates to the caller that it should be copied from the parent commit. To indicate that this update is a no-op (but this could not be determined by isEmpty()), return the sentinel NO_OP_UPDATE.

Throws:

java.io.IOException - if a lower-level error occurred.

allowWriteToNewRef

public boolean allowWriteToNewRef()

verifyComment

protected void verifyComment(Comment c)
