Method Detail

getImage

public java.awt.Image getImage()

open

public void open()
          throws java.io.IOException

Description copied from interface: Document

Opens the Document and loads any associated data into the appropriate data structures. If the implementation of this method completes successfully, the LazyLoadable.isOpen() method should then return true.

Specified by:

open in interface Document

Overrides:

open in class DefaultDocument

Throws:

java.io.IOException

See Also:

Document.open()

close

public void close()
           throws java.io.IOException

Description copied from interface: Document

Closes the Document and unloads any associated data. When this method returns, the state of the Document object should be equivalent to when the Document object has just been instantiated but not yet opened.

Specified by:

close in interface Document

Overrides:

close in class DefaultDocument

Throws:

java.io.IOException

See Also:

Document.close()

isNew

public boolean isNew()

Description copied from interface: Document

Returns true if the document's data has never been saved.

Specified by:

isNew in interface Document

Overrides:

isNew in class DefaultDocument

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

Overrides:

getIcon in class DefaultDisplayable

See Also:

Displayable.getIcon()

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 DefaultDocument

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 DefaultDocument

setURL

public void setURL(java.net.URL url)

Description copied from class: DefaultNode

Sets the URL associated with this DefaultNode and recaches the DefaultNode in the NodeFactory with the new URL so that subsequent queries for the DefaultNode will return successfully.

Specified by:

setURL in interface Locatable

Overrides:

setURL in class DefaultNode

See Also:

Locatable.setURL(URL), DefaultDocument.setURL(URL)
