All Superinterfaces:

ZSerializable

All Known Implementing Classes:

public interface ZLayoutManager

extends ZSerializable

ZLayoutManager represents an object that can layout the children of a node.

Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.
