Method Details

useDefaultInitValues

protected abstract boolean useDefaultInitValues()

does the language care about using type-appropriate default values? For Java, the answer is yes (ints should get a default value of 0, null for pointers, etc.). For JavaScript, the answer is no, as any variable can hold the value 'undefined'.

can lexical reads / writes access globals?

topLevelFunctionsInGlobalScope

protected boolean topLevelFunctionsInGlobalScope()

defaultCatchType
