public class RemoteRefUpdate extends Object
Represent request and status of a remote ref update. Specification is provided by client, while status is handled byPushProcess
class, being read-only for client.Client can create instances of this class directly, basing on user specification and advertised refs (

RemoteRefUpdate
public RemoteRefUpdate(Repository localDb, String srcRef, String remoteName, boolean forceUpdate, String localName, ObjectId expectedOldObjectId) throws IOException
Construct remote ref update request by providing an update specification. Object is created with defaultRemoteRefUpdate.Status.NOT_ATTEMPTED
status and no message.- Parameters:
localDb
- local repository to push from.srcRef
- source revision - any string resolvable byRepository.resolve(String)
. This resolves to the new object that the caller want remote ref to be after update. Use null orObjectId.zeroId()
string for delete request.remoteName
- full name of a remote ref to update, e.g. "refs/heads/master" (no wildcard, no short name).forceUpdate
- true when caller want remote ref to be updated regardless whether it is fast-forward update (old object is ancestor of new object).localName
- optional full name of a local stored tracking branch, to update after push, e.g. "refs/remotes/zawir/dirty" (no wildcard, no short name); null if no local tracking branch should be updated.expectedOldObjectId
- optional object id that caller is expecting, requiring to be advertised by remote side before update; update will take place ONLY if remote side advertise exactly this expected id; null if caller doesn't care what object id remote side advertise. UseObjectId.zeroId()
when expecting no remote ref with this name.- Throws:
IOException
- when I/O error occurred during creatingTrackingRefUpdate
for local tracking branch or srcRef can't be resolved to any object.IllegalArgumentException
- if some required parameter was null
-
RemoteRefUpdate
public RemoteRefUpdate(Repository localDb, Ref srcRef, String remoteName, boolean forceUpdate, String localName, ObjectId expectedOldObjectId) throws IOException
Construct remote ref update request by providing an update specification. Object is created with defaultRemoteRefUpdate.Status.NOT_ATTEMPTED
status and no message.- Parameters:
localDb
- local repository to push from.srcRef
- source revision. Use null to delete.remoteName
- full name of a remote ref to update, e.g. "refs/heads/master" (no wildcard, no short name).forceUpdate
- true when caller want remote ref to be updated regardless whether it is fast-forward update (old object is ancestor of new object).localName
- optional full name of a local stored tracking branch, to update after push, e.g. "refs/remotes/zawir/dirty" (no wildcard, no short name); null if no local tracking branch should be updated.expectedOldObjectId
- optional object id that caller is expecting, requiring to be advertised by remote side before update; update will take place ONLY if remote side advertise exactly this expected id; null if caller doesn't care what object id remote side advertise. UseObjectId.zeroId()
when expecting no remote ref with this name.- Throws:
IOException
- when I/O error occurred during creatingTrackingRefUpdate
for local tracking branch or srcRef can't be resolved to any object.IllegalArgumentException
- if some required parameter was null
-
RemoteRefUpdate
public RemoteRefUpdate(Repository localDb, String srcRef, ObjectId srcId, String remoteName, boolean forceUpdate, String localName, ObjectId expectedOldObjectId) throws IOException
Construct remote ref update request by providing an update specification. Object is created with defaultRemoteRefUpdate.Status.NOT_ATTEMPTED
status and no message.- Parameters:
localDb
- local repository to push from.srcRef
- source revision to label srcId with. If null srcId.name() will be used instead.srcId
- The new object that the caller wants remote ref to be after update. Use null orObjectId.zeroId()
for delete request.remoteName
- full name of a remote ref to update, e.g. "refs/heads/master" (no wildcard, no short name).forceUpdate
- true when caller want remote ref to be updated regardless whether it is fast-forward update (old object is ancestor of new object).localName
- optional full name of a local stored tracking branch, to update after push, e.g. "refs/remotes/zawir/dirty" (no wildcard, no short name); null if no local tracking branch should be updated.expectedOldObjectId
- optional object id that caller is expecting, requiring to be advertised by remote side before update; update will take place ONLY if remote side advertise exactly this expected id; null if caller doesn't care what object id remote side advertise. UseObjectId.zeroId()
when expecting no remote ref with this name.- Throws:
IOException
- when I/O error occurred during creatingTrackingRefUpdate
for local tracking branch or srcRef can't be resolved to any object.IllegalArgumentException
- if some required parameter was null
-
RemoteRefUpdate
public RemoteRefUpdate(RemoteRefUpdate base, ObjectId newExpectedOldObjectId) throws IOException
Create a new instance of this object basing on existing instance for configuration. State (likegetMessage()
,getStatus()
) of base object is not shared. Expected old object id is set up from scratch, as this constructor may be used for 2-stage push: first one being dry run, second one being actual push.- Parameters:
base
- configuration base.newExpectedOldObjectId
- new expected object id value.- Throws:
IOException
- when I/O error occurred during creatingTrackingRefUpdate
for local tracking branch or srcRef of base object no longer can be resolved to any object.

Method Detail
-
isMatching
public boolean isMatching()
Tells whether thisRemoteRefUpdate
is a placeholder for a "matching"RefSpec
.- Returns:
true
if this is a placeholder,false
otherwise- Since:
- 6.1
-
getExpectedOldObjectId
public ObjectId getExpectedOldObjectId()
Get expected old object id- Returns:
- expectedOldObjectId required to be advertised by remote side, as set in constructor; may be null.
-
isExpectingOldObjectId
public boolean isExpectingOldObjectId()
Whether some object is required to be advertised by remote side, as set in constructor- Returns:
- true if some object is required to be advertised by remote side, as set in constructor; false otherwise.
-
getNewObjectId
public ObjectId getNewObjectId()
Get new object id- Returns:
- newObjectId for remote ref, as set in constructor.
-
isDelete
public boolean isDelete()
Whether this update is a deleting update- Returns:
- true if this update is deleting update; false otherwise.
-
getRemoteName
public String getRemoteName()
Get name of remote ref to update- Returns:
- name of remote ref to update, as set in constructor.
-
