VCSManager

public VCSManager()

Method Detail

getVCSManager

public static VCSManager getVCSManager()

Gets the VCSManager instance that is active in the IDE.

Returns:

the VCSManager instance.

setVCSManager

public static void setVCSManager(VCSManager vcsManager)

checkOutUsingUI

public abstract java.util.concurrent.Future<java.lang.Boolean> checkOutUsingUI(VCSTask task)

Executes check outs asynchronously, with UI, through the given runnable task. The task can be monitored for progress during execution. This method may display a UI confirmation and must be called from an AWT event thread to prevent risk of deadlock.

Files will be batch-processed if necessary to ensure the best performance of the operation. Note that there are no preconditions for the URLs passed to this method, which may or may not be read-only, checked in, or version controlled. There is a guaranteed post-condition that, when the result of the operation is true, all given URLs are read/write regardless of whether they have been checked out during the operation.

Parameters:

task - the task to execute.

Returns:

the future result of the executed task.

checkOut

public abstract boolean checkOut(java.net.URL[] urls)

Executes check outs synchronously, and silently, on the calling thread.

Files will be batch-processed if necessary to ensure the best performance of the operation. Note that there are no preconditions for the URLs passed to this method, which may or may not be read-only, checked in, or version controlled. There is a guaranteed post-condition that, when the result of the operation is true, all given URLs are read/write regardless of whether they have been checked out during the operation.

Parameters:

urls - the URLs to check out.

Returns:

a verdict on whether files are read/write following the operation.

removeVCSListener

public abstract void removeVCSListener(VCSListener listener)

Removes a VCSListener from the VCSManager.

Parameters:

listener - the VCS listener.

getVersionName

Gets a name representing the current version of the given URL.

Returns:

the version name of the URL.

registerWorkspaceArtifact

public final void registerWorkspaceArtifact(java.lang.String path)

Register a path, relative to workspace directories, that locates other versionable artifacts to track.

Parameters:

path - a relative URL path to a file or directory.

getWorkspaceArtifacts

protected final java.util.Collection<java.lang.String> getWorkspaceArtifacts()

deregisterWorkspaceArtifact

@Deprecated
public final void deregisterWorkspaceArtifact(java.lang.String path)

Deprecated. not replaced. Artifacts must be registered on startup, and can no longer be deregistered.

Deregister a path, relative to workspace directories, that locates other versionable artifacts to track.

Parameters:

path - a relative URL path to a file or directory.

containsConflicts

public abstract boolean containsConflicts(java.net.URL url)

Asks whether the given URL contains diff3-style merge conflicts. When true the file may be handled in a special way by consumer code, in particular by being accessed through openConflictsStreamAsContributor(java.net.URL). This assists the prevention of parser failures and similar instabilities in the product when dealing with files containing conflicts.

Parameters:

url - the URL.

Returns:

a verdict on whether the URL contains conflicts.

openConflictsStreamAsContributor

public abstract java.io.InputStream openConflictsStreamAsContributor(java.net.URL url)
                                                              throws java.io.IOException

Opens an InputStream on the given URL, which contains diff3-style merge conflicts. The resulting stream is a partial reconstruction of the local contributor to the conflicts file, before the merge. It is the same as the contents of the conflicts file with all blocks from the local file selected, and blocks from the conflicting file ignored.

Parameters:

url - the URL to open.

Returns:

an InputStream on the deconstructed conflicts file.

Throws:

java.io.IOException - if an I/O error occurs while creating the input stream.

getContextMenuListeners

public abstract ContextMenuListener[] getContextMenuListeners()

Gets the list of context menu listeners currently registered against the the VCSManager.

Returns:

the registered context menu listeners for version control.

See Also:

oracle.ide.controller.ContextMenuListener}

getContextLocatables

public abstract Locatable[] getContextLocatables(Context context)

Gets the valid locatables from the context node selection. Composite nodes are expanded by this method.

Parameters:

context - the locatable context.

Returns:

the valid locatable context.

executeTaskImpl

protected abstract boolean executeTaskImpl(VCSTask task)

Implementation method.

getTaskProperties

protected final java.util.Map getTaskProperties(VCSTask task)

Implementation method.

deleteRecursively

public final void deleteRecursively(java.net.URL url)
                             throws java.io.IOException,
                                    java.lang.InterruptedException

Deletes the given URL, recursively processing all directories. This method offers a performance gain over a normal recursive invocation of URLFileSystem.delete(java.net.URL), because measures are taken to reduce queries and interactions with the version control system. This method may be slow to complete and must be called from a non-event thread.

Parameters:

url - the url (regular file or directory resource) to delete.

Throws:

java.io.IOException - if an I/O exception occurred while trying to delete the URL. The exception message will contain details on why the deletion failed.

java.lang.InterruptedException

deleteRecursively

public void deleteRecursively(java.net.URL url,
                              URLFilter filter,
                              boolean tolerant)
                       throws java.io.IOException,
                              java.lang.InterruptedException

Deletes the given URL, recursively processing all directories. This method offers a performance gain over a normal recursive invocation of URLFileSystem.delete(java.net.URL), because measures are taken to reduce queries and interactions with the version control system. This method may be slow to complete and must be called from a non-event thread.

Parameters:

url - the url (regular file or directory resource) to delete.

filter - a filter to control deletions, accepting files to delete. This value may be null, in which case all files are assumed to be deletable.

tolerant - a decision on whether to tolerate failed deletions.

Throws:

java.io.IOException - if an I/O exception occurred while trying to delete the URL. The exception message will contain details on why the deletion failed.

java.lang.InterruptedException
