The IlvLabelLayout class is the base class for
all label layout algorithms. This class is an abstract class and
cannot be used directly.
Subclasses of IlvLabelLayout
There are currently two subclasses:
- IlvRandomLabelLayout which randomizes the label positions for demonstration purpose.
- IlvAnnealingLabelLayout which carries out real label arrangement.
You can also create your own subclasses to
implement other label layout algorithms.
The label layout renderer always uses the IlvAnnealingLabelLayout.
You can use IlvRandomLayout or
your own label layout algorithm when you write Java™ code.
It is not possible to use IlvRandomLayout
or your own label layout algorithm in a diagram component based
on CSS styling.
Despite the fact that only subclasses of IlvLabelLayout
are directly used to obtain the layouts, it is still necessary to
learn about this class because it contains methods that are
inherited (or overridden) by its subclasses. And, of course, you
will need to understand it if you subclass it yourself.
