public abstract class AbstractStrategyBasic
extends AbstractStrategy

Partial implementation of the strategy interface that can be used to implement new basic transformations (like a rewrite rule system). This class has an attribute of type Strategy which corresponds to the default strategy if the transformation system cannot be applied. Note that this abstract class is used to compile the %strategy Tom instruction.
