All Known Implementing Classes:

GatherSideEffectSubexpressionsCallback.GetReplacementSideEffectSubexpressions, NameAnalyzer.FindReferences.NodeAccumulator

Enclosing class:

GatherSideEffectSubexpressionsCallback

static interface GatherSideEffectSubexpressionsCallback.SideEffectAccumulator

Used by GatherSideEffectSubexpressionsCallback to notify client code about side effect expressions that should be kept.

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.

Method Detail

classDefiningCallsHaveSideEffects

boolean classDefiningCallsHaveSideEffects()

Returns true if the "mixin" and "inherits" function calls should be treated as if they had side effects.

keepSubTree

void keepSubTree(Node original)

Adds subtree to the list of nodes that have side effects.

Parameters:

original - - root of the tree.

keepSimplifiedShortCircuitExpression

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.

Parameters:

original - - root of the and/or expression.

keepSimplifiedHookExpression

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.

Parameters:

hook - - root of the hook expression.

thenHasSideEffects - - then branch has side effects

elseHasSideEffects - - else branch has side effects
