Field Detail

WORKSPACES

public static final java.lang.String WORKSPACES
Constant identifying this object. Used by the workspaces navigator as part of its ID.

Constant Field Values
Constructor Detail

Workspaces

public Workspaces()
Default constructor. Required for JavaBean status.


Workspaces

public Workspaces(Workspaces workspaces)
Copy constructor.

Method Detail

copyTo

public java.lang.Object copyTo(java.lang.Object object)
Description copied from interface: Copyable
Copies the internal state of this object to the specified copy. If copy is null, then this method should create a new instance of this class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.

Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this object's state was copied.

There is a standard implementation pattern for the copyTo method that helps avoid problems that arise when a Copyable object is subclassed. The pattern is:

public Object copyTo( Object target )
{
final <this_class> copy =
target != null ? (<this_class>) target : new <this_class>();
copyToImpl( copy );
return copy;
} protected final void copyToImpl( <this_class> copy ) { super.copyToImpl( copy ); // if necessary // put code here for copying the properties of <this_class> }
The parameter passed into the copyToImpl method is the same type of this class. The responsibility of copyToImpl is to copy the state of this class through direct access of the fields. The copyToImpl method should not use getters and setters since these may be overridden, causing the state of this class to be incompletely copied.

Specified by:
copyTo in interface Copyable
Overrides:
copyTo in class ObservableDataFolder

copyToImpl

protected final void copyToImpl(Workspaces copy)
Design pattern for supporting strongly typed copying.


getWorkDirectory

public java.net.URL getWorkDirectory()
Returns:
The full pathname of the default root directory for all new Workspaces.

setWorkDirectory

public void setWorkDirectory(java.net.URL workDirectory)
Sets the default root directory for all new Workspaces.


getActiveWorkspaceURL

public java.net.URL getActiveWorkspaceURL()

setActiveWorkspaceURL

public void setActiveWorkspaceURL(java.net.URL workspaceURL)

getShortLabel

public java.lang.String getShortLabel()
Description copied from interface: Displayable
Returns a short label that can be displayed to the user. Generally, the value of the returned String is considered translatable and should therefore be placed in an appropriate resource file. When possible, the returned label should be reasonably short enough to show in the navigator or explorer windows but long enough to clearly identify and distinguish the Displayable.

Specified by:
getShortLabel in interface Displayable
Overrides:
getShortLabel in class DefaultDisplayable
See Also:
Displayable.getShortLabel()

getIcon

public javax.swing.Icon getIcon()
Description copied from class: DefaultFolder
Part of Element interface. The default implementation returns null, which causes a default folder icon to be used.

Specified by:
getIcon in interface Displayable
Overrides:
getIcon in class DefaultFolder
See Also:
Displayable.getIcon()

canAdd

public boolean canAdd(Element element)
Folder interface method. Returns true if the type of the specified Element exactly matches Workspace. Returns false otherwise.

Specified by:
canAdd in interface Folder
Overrides:
canAdd in class DefaultFolder
Returns:
true if and only if the specified Element is not null.
See Also:
Folder.canAdd(Element), DefaultFolder.canAdd(Element), Workspace

remove

public boolean remove(Element doc)
Description copied from class: DefaultFolder
Part of the Folder interface. The specified Element is removed from the child list. However, if the Element is null, this method does nothing. If the Element occurs more than once in the child list, then only the first instance is removed.

In order for the UI to get updated correctly, an appropriate UpdateMessage will need to be sent to Observers of the DefaultFolder. The policy in the IDE is that the class that changes the state of an object is responsible for firing the UpdateMessages for those changes. UpdateMessages are not fired by the changed object itself.

For a single UpdateMessage corresponding to DefaultFolder.remove(Element), you can fire the UpdateMessage using code like:

UpdateMessage.fireChildRemoved(folder, removedChild);

Specified by:
remove in interface Folder
Overrides:
remove in class DataFolder

setListOfChildren

public void setListOfChildren(java.util.List list)
Description copied from class: DataFolder
Fulfills the public accessor part of the Folder contract. Sets the child list of the DataFolder instance to match the specified List. Only objects in the List that can be cast to Element are added. The implementation uses the DefaultFolder.add(Element) method to add the child to the list, so that subclass implementations can override DefaultFolder.add(Element) without having to also override this method.

Overrides:
setListOfChildren in class DataFolder

isDirty

public boolean isDirty()
Description copied from interface: Dirtyable
True if the data in the object has been modified.

Specified by:
isDirty in interface Dirtyable
Overrides:
isDirty in class DataFolder

markDirty

public void markDirty(boolean dirty)
Description copied from interface: Dirtyable
Marks the data with the specified dirty state. This method is called markDirty(...) instead of setDirty(...) so that the JavaBeans Introspector will not mistakenly identify "dirty" as a JavaBean property.

Specified by:
markDirty in interface Dirtyable
Overrides:
markDirty in class DataFolder

setOwner

public void setOwner(Dirtyable owner)
Description copied from interface: SubDirtyable
This method should be called to set the document in which a SubDirtyable implementation will be persisted.

Specified by:
setOwner in interface SubDirtyable
Parameters:
owner - The Dirtyable object in which this SubDirtyable will be saved.

currentActiveWorkspace

public Workspace currentActiveWorkspace()
Returns the currently active Workspace associated with this Workspaces. If there is no currently active Workspace, null is returned This method is called currentActiveWorkspace instead of getActiveWorkspace in order to avoid having the "_activeWorkspace" property get picked up by the Introspector.


setActiveWorkspace

public void setActiveWorkspace(Workspace workspace)
Sets the currently active Workspace associated with this Workspaces.


getActiveProjectMap

public java.util.Map getActiveProjectMap()
Gets a map containing information about what project for a given workspace. This method should only be called by the persistance mechanism. It builds the map everytime the method is called.


setActiveProjectMap

public void setActiveProjectMap(java.util.Map map)
Sets the active project map. If the workspaces children information has already been initialized, it initializes the active projects on each workspace child, otherwise, this will be done when the children are initialized.
