Method Detail

findOrCreateNodes

public static final Locatable[] findOrCreateNodes(java.net.URL[] urls)

Finds or creates locatables for the given URLs, using the node cache. This method will create default Folder instances for directory path URLs.

Parameters:

urls - the array of URLs for the nodes to find or create.

Returns:

the resulting array of locatables.

convertNodesToURLs

public static final java.net.URL[] convertNodesToURLs(Locatable[] locatables)

Converts the given locatables into their associated URLs.

Parameters:

locatables - the array of locatables to convert.

Returns:

the resulting array of URLs.

convertNodesToURLs

public static final java.net.URL[] convertNodesToURLs(java.util.Collection<? extends Locatable> locatables)

Converts the given locatables into their associated URLs.

Parameters:

locatables - the collection of locatables to convert.

Returns:

the resulting array of URLs.

isElementSaveUpdate

public static final boolean isElementSaveUpdate(java.lang.Object observed,
                                                UpdateMessage change)

Asks whether the given update message indicates that the observed node has been saved. This is determined by checking before and after values of the element's DIRTY attribute.

Parameters:

observed - the observed subject.

change - the update message.

Returns:

a verdict on whether the update message is a save.

getValidLocatables

public static final Locatable[] getValidLocatables(java.lang.Object[] nodes,
                                                   URLFilter filter)

Gets the valid locatables from the given node selection.

Parameters:

nodes - the original node selection.

filter - a filter that accepts valid locatable URLs. (null-capable)

Returns:

the valid locatable array.

getLocatableURL

public static final java.net.URL getLocatableURL(java.lang.Object node)

Gets the given node's URL, if the node is a locatable. This method performs the instance test and cast. It may be used as a shorthand for (node instanceof Locatable ? ((Locatable)node).getURL() : null).

Parameters:

node - the node.

Returns:

the node's URL, if it's a valid locatable.

findCachedNodes

public static final Node[] findCachedNodes(URLFilter filter)

Finds nodes cached in the IDE whose files satisfy the given URL filter.

Parameters:

filter - a filter that accepts URLs for cached nodes. (null-capable)

Returns:

the array of accepted nodes.

getDirtyNodes

public static final Node[] getDirtyNodes(Node[] nodes)

Gets the nodes from the given selection which are dirty.

Parameters:

nodes - an array of nodes.

Returns:

the resulting array of nodes which are dirty.

getCachedDirectoryNodes

public static final Node[] getCachedDirectoryNodes(java.net.URL[] directoryUrls)

Gets all cached nodes with URLs in the given directories.

Parameters:

directoryUrls - the array of directories for returned cached nodes.

Returns:

the array of cached nodes.

getCachedBaseURLNodes

public static final Node[] getCachedBaseURLNodes(java.net.URL[] baseUrls)

Gets all cached nodes with URLs underneath the given base URLs.

Parameters:

baseUrls - the array of base URLs for returned cached nodes.

Returns:

the array of cached nodes.

listBinaryExtensions

@Deprecated
public static final java.lang.String[] listBinaryExtensions()

Deprecated. replaced by VCSFileSystemUtils.listBinaryExtensions().

List all recognized binary file extensions registered with the IDE. Extensions are in the sanitized form, so they will include the leading '.' before the suffix.

Returns:

the array of recognized extensions.

findCachedWorkspaces

public static final Workspace[] findCachedWorkspaces()

Gets all open Workspace type nodes cached in the NodeFactory.

Returns:

the array of cached workspace nodes.

findCachedProjects

public static final Project[] findCachedProjects()

Gets all open Project type nodes cached in the NodeFactory.

Returns:

the array of cached project nodes.

findCachedProjects

@Deprecated
public static final Project[] findCachedProjects(boolean openWorkspaces)

Deprecated. replaced by findCachedProjects(). Workspaces no longer need to be opened in order to discover their children.

Gets all open Project type nodes cached in the NodeFactory.

Parameters:

openWorkspaces - a decision on whether workspaces should be opened. If true and the calling thread is not the AWT event dispatcher, please be aware that there may be risk of deadlock while this method is blocking.

Returns:

the array of cached project nodes.

fireProjectStructuresChanged

@Deprecated
public static final void fireProjectStructuresChanged()

Deprecated. replaced with VCSCommand.fireFileStructureChanged(java.net.URL[]) and VCSFileEventSender.fireFileStructureChanged(java.net.URL[]).

Parameters:

projectContentsUrls - the URLs which have been affected by an operation.

fireVetoableCanRemoveChildren

public static final void fireVetoableCanRemoveChildren(java.lang.Object[] elements)
