Class RemoteRefUpdate

java.lang.Object

org.eclipse.jgit.transport.RemoteRefUpdate

public class RemoteRefUpdate
extends Object

Represent request and status of a remote ref update. Specification is provided by client, while status is handled by PushProcess class, being read-only for client.

Client can create instances of this class directly, basing on user specification and advertised refs (Connection or through Transport helper methods. Apply this specification on remote repository using Transport.push(org.eclipse.jgit.lib.ProgressMonitor, java.util.Collection) method.

Constructor Detail

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 default RemoteRefUpdate.Status.NOT_ATTEMPTED status and no message.

Parameters:

localDb - local repository to push from.

srcRef - source revision - any string resolvable by Repository.resolve(String). This resolves to the new object that the caller want remote ref to be after update. Use null or ObjectId.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. Use ObjectId.zeroId() when expecting no remote ref with this name.

Throws:

IOException - when I/O error occurred during creating TrackingRefUpdate 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 default RemoteRefUpdate.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. Use ObjectId.zeroId() when expecting no remote ref with this name.

Throws:

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

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 or ObjectId.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).

RemoteRefUpdate

public RemoteRefUpdate(RemoteRefUpdate base,
                       ObjectId newExpectedOldObjectId)
                throws IOException

Create a new instance of this object basing on existing instance for configuration. State (like getMessage(), 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 creating TrackingRefUpdate for local tracking branch or srcRef of base object no longer can be resolved to any object.
