Interface ISVNEditor

All Superinterfaces:
ISVNDeltaConsumer
All Known Implementing Classes:
SVNReplicationEditor

public interface ISVNEditor
extends ISVNDeltaConsumer

The ISVNEditor interface is used by SVNRepository to update versioned files/dirs, check out files/dirs from a repository, commit changes to a repository, take status of files/dirs, get differences between files.

When used for updating (checking out, getting differences or status), an implementor should provide its own appropriate implementation of the ISVNEditor interface along with a reporter baton (ISVNReposrterBaton) to a corresponding
method of an SVNRepository driver. Reporter baton will be used to describe the state of local dirs/files - their current revisions, whether a file/dir is deleted or switched. An editor is invoked after the reporter baton finishes its work.
It is used to "edit" the state of files/dirs, where "edit" may mean anything: applying changes in updating, switching, checking out (what really changes the state), or handling changes in getting status or differences (what is only used to inform about, show,
separately store changes, and so on). The concrete behaviour of the editor is implemented by the provider of that editor.

The other kind of using ISVNEditor is committing changes to a repository. Here an editor is given to a caller, and the caller himself describes the changes of local files/dirs. All that collected info is then committed in a single transaction
when a caller invokes the closeEdit() method of the editor. For more information
on using editors, please, read these on-line articles:

Method Detail

targetRevision

void targetRevision(long revision)
                    throws SVNException
Sets the target revision the operation is running for. For example, the target revision to which an update is running.

Parameters:
revision - a revision number
Throws:
SVNException

openRoot

void openRoot(long revision)
              throws SVNException
Opens the root directory on which the operation was invoked. All property changes as well as entries adding/deletion will be applied to this root directory. When coming back up to this root (after traversing the entire tree) you should close the root
by calling closeDir().

Parameters:
revision - the revision number of the root directory
Throws:
SVNException

deleteEntry

void deleteEntry(java.lang.String path,
                 long revision)
                 throws SVNException
Deletes an entry.

In a commit - deletes an entry from a repository. In an update - deletes an entry locally (since it has been deleted in the repository). In a status - informs that an entry has been deleted.

Parameters:
path - an entry path relative to the root directory opened by openRoot()
revision - the revision number of path
Throws:
SVNException

absentDir

void absentDir(java.lang.String path)
               throws SVNException
Indicates that a path is present as a subdirectory in the edit source, but can not be conveyed to the edit consumer (perhaps because of authorization restrictions).

Parameters:
path - a dir path relative to the root directory opened by openRoot()
Throws:
SVNException

absentFile

void absentFile(java.lang.String path)
                throws SVNException
Indicates that a path is present as a file in the edit source, but can not be conveyed to the edit consumer (perhaps because of authorization restrictions).

Parameters:
path - a file path relative to the root directory opened by openRoot()
Throws:
SVNException

addDir

void addDir(java.lang.String path,
            java.lang.String copyFromPath,
            long copyFromRevision)
            throws SVNException
Adds a directory.

In a commit - adds a new directory to a repository. In an update - locally adds a directory that was added in the repository. In a status - informs about a new directory scheduled for addition.

If copyFromPath is not null then it says that path is copied from copyFromPath located in copyFromRevision.

Parameters:
path - a directory path relative to the root directory opened by openRoot()
copyFromPath - an ancestor of the added directory
copyFromRevision - the revision of the ancestor
Throws:
SVNException

openDir

void openDir(java.lang.String path,
             long revision)
             throws SVNException
Opens a directory. All property changes as well as entries adding/deletion can be applied to this directory.

Parameters:
path - a directory path relative to the root directory opened by openRoot()
revision - the revision of the directory
Throws:
SVNException

changeDirProperty

void changeDirProperty(java.lang.String name,
                       SVNPropertyValue value)
                       throws SVNException
Changes the value of a property of the currently opened/added directory.
