          ptolemy.copernicus.java.ConstantLoopUnroller

public class ConstantLoopUnroller
extends soot.BodyTransformer

A Transformer that attempts to determine the bounds of a loop at compile time, and then unroll the loop. In terms of code generation, the primary value of this transformation is that it reduces the control logic of the source code, which can increase the power of other compile-time optimizations.

v

public static ConstantLoopUnroller v()

Return an instance of this transformer that will operate on the given model. The model is assumed to already have been properly initialized so that resolved types and other static properties of the model can be inspected.
