Intermediate Processors
This section describes the intermediate processors that are available. For a description of what intermediate processors actually are, seeĀ KLay Layered.
Each intermediate processor is described by its required preconditions, its postconditions, the slot where it should be placed in and dependencies to intermediate processors in the same slot. The descriptions are kept very brief, since layout processors are usually well documented. Programmers using layout processors need not worry about dependencies. However, when adding a new processor, dependencies matter. For more information, see the documentation of IntermediateLayoutProcessor.
The following table provides an overview of all available layout processors and the slots they can be placed in. Note that a processor may appear in more than one slot. Within each slot, processors are ordered by theirs dependencies on each other.
Slot | Processor | Tested |

Before phase 3 | Layer Constraint Processor | |
Before phase 4 | In Layer Constraint Processor | |
