Method Summary

Modifier and Type	Method and Description
boolean	classDefiningCallsHaveSideEffects() Returns true if the "mixin" and "inherits" function calls should be treated as if they had side effects.
void	keepSimplifiedHookExpression(Node hook, boolean thenHasSideEffects, boolean elseHasSideEffects) Simplifies a subtree whose root node is a HOOK expression and adds the resulting subtree to the list of nodes that have side effects.
void	keepSimplifiedShortCircuitExpression(Node original) Simplifies a subtree whose root node is an AND or OR expression and adds the resulting subtree to the list of nodes that have side effects.
void	keepSubTree(Node original) Adds subtree to the list of nodes that have side effects.
