Does nothing.

Method Detail

setBoundingPoints2DRef

public void setBoundingPoints2DRef(Polygon2D p)

Recursively calls setBoundingPoints2DRef() on all of the contained views.

Chewbacca is a Wookie. Wookies are from Endor. Does this make sense? Or course it doesn't make sense! If it doesn't make sense, you must acquit!

Specified by:

setBoundingPoints2DRef in interface View

Overrides:

setBoundingPoints2DRef in class ViewImpl

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Parameters:

p - is the polygon bounds. Assumes the bounds are already in local coordinates.

setAttachedGraphicalObject

public GraphicalObject setAttachedGraphicalObject(GraphicalObject gob)

Also modify the attached GraphicalObject for every contained View.

Specified by:

setAttachedGraphicalObject in interface View

Overrides:

setAttachedGraphicalObject in class ViewImpl

Parameters:

gob - is the GraphicalObject to attach.

add

public View add(View v)

Description copied from interface: MultiView

Add a view to the MultiView, setting the GraphicalObject the added View is attached to (via View.setAttachedGraphicalObject(GraphicalObject)) to be the same as the one this MultiView is attached to.

Specified by:

add in interface MultiView

Following copied from interface: edu.berkeley.guir.lib.satin.view.MultiView

Parameters:

v - is the view to add.

Returns:

a reference to v.

remove

public View remove(View v)

Description copied from interface: MultiView

Remove a view.

Specified by:

remove in interface MultiView

Following copied from interface: edu.berkeley.guir.lib.satin.view.MultiView

Parameters:

v - is the view to remove.

Returns:

a reference to v.

clear

public void clear()

Description copied from interface: MultiView

Clear all of the views.

Specified by:

clear in interface MultiView

getBoundingPoints2DRef

public Polygon2D getBoundingPoints2DRef()

Returns the bounding box of all of the contained AND visible views.

Specified by:

getBoundingPoints2DRef in interface View

Overrides:

getBoundingPoints2DRef in class ViewImpl

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

the polygon bounds.

iterator

public Iterator iterator()

Get an iterator over the views, sorted by their display values (high to low, descending order).

Specified by:

iterator in interface MultiView

Following copied from interface: edu.berkeley.guir.lib.satin.view.MultiView

Returns:

an Iterator of View objects.

get

public View get(int index)

Description copied from interface: MultiView

Get the view at the specified index.

Specified by:

get in interface MultiView

Following copied from interface: edu.berkeley.guir.lib.satin.view.MultiView

Parameters:

index - is the index in the list to retrieve from.

Returns:

the View at the index, or null if it does not exist.

contains

public boolean contains(View v)

Description copied from interface: MultiView

Check if we contain the specified view.

Specified by:

contains in interface MultiView

size

public int size()

Description copied from interface: MultiView

Get the number of views contained.

Specified by:

size in interface MultiView

getValidViews

protected Iterator getValidViews()

Get an iterator over the valid views (views with display values greater than 0), sorted by their display values (high to low, descending order).

getViewDisplayValue

public float getViewDisplayValue()

Description copied from interface: View

Check whether or not this view is valid, ie can and should be displayed. This can be a combination of any range of parameters. For example, you could say that this view is valid when:

• The GraphicalObject's zoom level is within a certain range.
• The GraphicalObject has debugging information turned on.

Specified by:

getViewDisplayValue in interface View

Returns:

Always returns 1.

isVisible

public boolean isVisible()

Checks if any contained views are visible.

Specified by:

isVisible in interface View

Overrides:

isVisible in class ViewImpl

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

true if the view is visible, false otherwise.

sortViewsByDisplayValue

protected void sortViewsByDisplayValue()

Sort the views by their display values, from high to low values (descending order).

render

public void render(SatinGraphics g)

Description copied from interface: View

Render this view. Use (0,0) as the top-left corner of this view. Any transformations that the attached GraphicalObject has will automatically be applied, so all you have to do is render the view normally.

Specified by:

render in interface View

toString

public String toString()

Print out a list of all of the contained views.

Overrides:

toString in class ViewImpl

clone

public Object clone()

Description copied from interface: View

Implementation of the Sorceror's Apprentice algorithm. Needs to be a DEEP clone.

Specified by:

clone in interface View

Overrides:

clone in class ViewImpl

clone

protected DefaultMultiViewImpl clone(DefaultMultiViewImpl vm)

Clone chain.
