Interface ISVNEditor

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

abortEdit

public void abortEdit()
Aborts the current running editor due to errors occured.

If an exception is thrown from an editor's method, call this method to abort the editor.

Throws: SVNException

absentDir

public void absentDir(String path)
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

public void absentFile(String path)
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

public void addDir(String path, String copyFromPath, long copyFromRevision)
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

addFile

public void addFile(String path, String copyFromPath, long copyFromRevision)
Adds a file.

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

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

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

Throws: SVNException

changeDirProperty

public void changeDirProperty(String name, String value)
Changes the value of a property of the currently "opened"/"added" directory.

Parameters: name the name of a property to be changed value new property value

Throws: SVNException

See Also: ISVNEditor

changeFileProperty

public void changeFileProperty(String path, String name, String value)
Changes the value of a property of an opened file.

Parameters: path a file path relative to the root directory opened by openRoot() name a file property name value a new value for the property

Throws: SVNException

closeDir

public void closeDir()
Closes the currently opened directory fixing all changes of its properties and/or entries. Closing a directory picks up an editor to a parent directory.

Throws: SVNException

closeEdit

public SVNCommitInfo closeEdit()
Closes this editor finalizing the whole operation the editor was used for. In a commit - sends collected data to commit a transaction.

Returns: a committed revision information

Throws: SVNException

closeFile

public void closeFile(String path, String textChecksum)
Closes the opened file fixing all properties and/or contents changes.

Parameters: path a file path relative to the root directory opened by openRoot() textChecksum an MD5 checksum for the modified file

Throws: SVNException if the calculated upon the actual changed contents checksum does not match the expected textChecksum

deleteEntry

public void deleteEntry(String path, long revision)
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

openDir

public void openDir(String path, long revision)
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

openFile

public void openFile(String path, long revision)
Opens a file. After it's opened, apply delta to its contents or change the file properties.

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

Throws: SVNException

openRoot

public void openRoot(long revision)
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

targetRevision

public void targetRevision(long revision)
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
