Method Summary

Modifier and Type	Method and Description
Node	accept(NodeVisitor<? extends LexicalContext> visitor) Provides a means to navigate the IR.
<R> R	accept(TranslatorNodeVisitor<? extends LexicalContext,R> visitor) Provides a means to navigate the IR.
Block	getBlock() Return the block to be executed
boolean	isSynthetic() Tells if this is a synthetic block statement or not.
boolean	isTerminal() Is this a terminal statement, i.e.
BlockStatement	setBlock(Block block) Reset the block to be executed
void	toString(StringBuilder sb, boolean printType) Print logic that decides whether to show the optimistic type or not - for example it should not be printed after just parse, when it hasn't been computed, or has been set to a trivially provable value
