Package org.axsl.area Description

Interfaces useful in the creation of an AreaTree that is backed by an FOTree.

The process of laying an FOTree out into an AreaTree, while quite complex, requires only a small subset of the information that is available in the FOTree and AreaTrees. The content, ordering, and properties are already known and recorded in the FOTree. These interfaces therefore provide two main services to the layout systems that use them: 1) The sizes of the various areas (the locations are not really needed by the layout systems), and 2) The ability to create new areas as needed.

The Area-W implementation therefore is responsible to make sure that the areas are properly positioned and for enforcing size constraints.
