D
- the kind of DockElement
this converter handlesL
- the kind of data this converter uses as intermediate formatpublic interface DockConverter<D extends DockElement,L>
A DockConverter
can store or load content which is related
to a certain kind of DockElement
.
The content of an element is first converted in a special intermediate form
represented by some object of type L
. This intermediate object
can then be written as byte-stream or in xml.

String getID()
L getLayout(D element, Map<Dockable,Integer> children)
element
. This method should create
a new instance of the layout object, that new object should not be
tied to element
in any way. A layout can be living for
a long period of time and might be used on another dockable
object.
element
- the element for which a new layout should be createdchildren
- a map containing unique identifiers for the children
of the element. Children which are not in this map should not be
stored in the layout.children.size()
(excl.). The
same identifiers will be used as indices by a LocationEstimationMap
. See
also DockFactory.estimateLocations(Object, LocationEstimationMap)
.
void setLayout(D element, L layout, Map<Integer,Dockable> children)
layout
and changes the layout of
element
accordingly. This method should remove all
children from element
and add new children.
