soot.toolkits.scalar.ConstantInitializerToTagTransformer

public class ConstantInitializerToTagTransformer
extends SceneTransformer

This is the reverse operation of the ConstantValueToInitializerTransformer. We scan for methods that initialize a final field with a constant value and create a ConstantValueTag from this value. Afterwards, the assignment in the method is removed. If runs empty, it is deleted as well.
