Constructor Detail

CmtFolder

public CmtFolder(CmtModel model)

Method Detail

getShortLabel

public java.lang.String getShortLabel()

Gets a short label for display purpose.

Specified by:

getShortLabel in interface Displayable

Returns:

a short descriptive label. For example; an unqaualified file name.

getLongLabel

public java.lang.String getLongLabel()

Gets a fully qualified label for display purpose.

Specified by:

getLongLabel in interface Displayable

Returns:

a long descriptive label. For example; a fully qualified file name.

getData

public java.lang.Object getData()

Gets the data object that implements this interface.

Specified by:

getData in interface Data

Returns:

object implementing this interface.

getIcon

public javax.swing.Icon getIcon()

Description copied from interface: Displayable

Returns an Icon that can be shown in association with this Displayable. Typically the icon will be used in a tree control or list control. Therefore the icon must fit naturally within the space normally given to items within those controls. Such icons are usually 16x16 in size or, if there is a one-pixel transparent padding around the edge, 18x18 in size. It is strongly recommended that icons returned by this method be either 16x16 or 18x18 in size. If null is returned, the control may show a default icon, or it may show no icon, whichever is appropriate.

Specified by:

getIcon in interface Displayable

Returns:

the Icon for this node instance

getToolTipText

public java.lang.String getToolTipText()

Description copied from interface: Displayable

Returns the tool tip text to show when the mouse pointer pauses over a UI component that represents this Displayable. In many cases it may be appropriate for this method to return the same value as Displayable.getLongLabel().

Specified by:

getToolTipText in interface Displayable

Returns:

the ToolTip for this node instance

mayHaveChildren

public boolean mayHaveChildren()

Description copied from interface: Element

This method is part of the Element interface to provide a convenient way of determining whether an object may have children without having to test the object's type with the instanceof operator or having to downcast to a more specific type.

An implementation of Element that represents a leaf in a tree structure should return false from this method. An implementation of Element that could represent a non-leaf in a tree structure should return true from this method, even if it does not currently contain any children.

Specified by:

mayHaveChildren in interface Element

Returns:

true if this Element may contain children.

getChildren

public java.util.Iterator getChildren()

Description copied from interface: Element

This method is part of the Element interface to provide a convenient way of getting an Iterator over any contained child Elements without having to test the object's type with the instanceof operator or having to downcast to a more specific type.

An implementation of Element that represents a leaf in a tree structure should return null from this method. An implementation of Element that could represent a non-leaf in a tree structure should return either an Iterator over the child Elements or null if there are no children.

Specified by:

getChildren in interface Element

Returns:

an Iterator of any children held by this Element, else null.

getAttributes

public Attributes getAttributes()

Returns oracle.ide.model.DefaultAttributes.EMPTY_ATTRIBUTES;

Specified by:

getAttributes in interface Element

add

public boolean add(Element element)

Add the specified Element to this Folder.

Specified by:

add in interface Folder

add

public void add(int index,
                Element element)

remove

public boolean remove(Element element)

Remove the specified Element from this Folder.

Specified by:

remove in interface Folder

Parameters:

element - Element to be removed from this container.

canRemove

public boolean canRemove(Element element)

Description copied from interface: Folder

Other classes can call this method to determine whether the specified Element can be removed from this Folder.

Specified by:

canRemove in interface Folder

Parameters:

element - the Element being checked for removal from this folder

Returns:

TRUE if the specified element can be removed from this folder in the specified context. Quick responses are appreciated, since this method is used to enable/disable the Delete accelerator key in the Navigator with every context change.

canAdd

public boolean canAdd(Element element)

Description copied from interface: Folder

Other classes can call this method to determine whether the given Element can be added to the Folder.

Specified by:

canAdd in interface Folder

Parameters:

element - the Element that is about to be added to this Folder.

Returns:

true if the specified Element can be added to this Folder; false if the Element cannot be added.

containsChild

public boolean containsChild(Element child)

Description copied from interface: Folder

Returns true if the folder contains the specified child Element; returns false otherwise.

Specified by:

containsChild in interface Folder

size

public int size()

Description copied from interface: Folder

Returns the current number of children in the folder.

Specified by:

size in interface Folder

removeAll

public void removeAll()

Description copied from interface: Folder

Removes all children from the folder.

Specified by:

removeAll in interface Folder

getCmtModel

public CmtModel getCmtModel()

Specified by:

getCmtModel in interface CmtModelNode

setCmtModel

public void setCmtModel(CmtModel model)

Specified by:

setCmtModel in interface CmtModelNode

getSubcomponent

public CmtSubcomponent getSubcomponent()

Specified by:

getSubcomponent in interface CmtModelNode

release

public void release()

Specified by:

release in interface CmtModelNode

getUserObject

public java.lang.Object getUserObject()

getName

public java.lang.String getName()

Specified by:

getName in interface CmtModelNode

getURL

public java.net.URL getURL()

Description copied from interface: Locatable

Returns the URL that identifies this Locatable. Parts of the IDE will use the value of this URL as a hash key for caching UI components for this Locatable. Therefore, URL uniqueness is important.

Specified by:

getURL in interface Locatable

Returns:

The URL identifying this Locatable.

setURL

public void setURL(java.net.URL url)

Description copied from interface: Locatable

Sets the URL associated with this Locatable. It is important that the URL only be changed when the Locatable has just been created or when all caches keyed on the previous URL can also be updated.

Specified by:

setURL in interface Locatable

Parameters:

url - The URL to set.
